# === CONSTRAINTS ===
constraints:
  - "All prices are US Amazon street prices fetched 2026-08-05; every comparison-table row states whether the price is for a KIT (battery + charger included) or TOOL ONLY"
  - "Two picks are TOOL ONLY at the quoted price — the RYOBI RY402110 ($223) and the Husqvarna 525iLST (dealer-set) — so budget for a battery and charger on top before comparing them against kit rows"
  - "Runtime varies significantly with line thickness, vegetation density, and speed setting — quoted runtimes are manufacturer estimates under moderate load with the specific battery named"
  - "Battery platforms are proprietary — choosing a trimmer locks you into that brand's battery ecosystem; attachment-capable models mostly take brand-specific attachments"
  - "Gas-equivalence figures (26cc, 30cc, 31cc, 1.76 HP) are manufacturer marketing claims, not independently measured test results"

# === SKIP CONDITIONS ===

# Best Cordless String Trimmers (2026)

## What are the best cordless string trimmers in 2026?

## TL;DR

**Top pick: Ryobi RY402110 40V HP Whisper ($223, tool only)** — 2026 shootout homeowner winner, 17" swath, 0.105" line; add a 6.0 Ah battery + charger [src1]. **Best value: Greenworks 60V ST60L254 ($155.39 kit, 2.5 Ah + charger)** — 16" swath, 60V, 4-year warranty [src5, src6]. **Best budget: WORX WG163 ($84.99 kit, two 20V batteries + charger)** — 5.5 lb, 2-in-1 trimmer/edger [src5, src6].

## Summary

Cordless string trimmers continue to displace gas in 2026, but the August price check changes which pick makes sense. Pro Tool Reviews' 2026 shootout (published 18 March 2026) placed the **Ryobi RY402110 40V HP Whisper Series** at the top of the homeowner category at 90 points — a 17-inch cutting swath, 0.105" line, brushless motor and carbon fiber Whisper shaft, measured at 5,621 RPM [src1]. It remains the best-tested homeowner trimmer here, but **the Amazon listing at $223 is the TOOL-ONLY SKU**: no battery, no charger. Ryobi's kit is the RY402110VNM, and Pro Tool Reviews lists the pair at $249 bare / $329 kit, so the 6.0 Ah battery and rapid charger are roughly an $80 premium at MSRP and more if bought separately [src1]. Compare that $223 against the kit rows below, not instead of them. More than 90% of battery string trimmers tested by Consumer Reports earn above-average marks for both trimming and edging, giving them a slight performance edge over gas models in those categories [src3]. The **Husqvarna 525iLST** (93 points) took the professional category with the largest cutting swath in the test at 18.1" and 0.105" line capability — also a tool-only product, and one Husqvarna sells through dealers with no online price [src1, src9].

If you want a trimmer that works the day it arrives, the kit rows have moved a long way since June. The **Greenworks 60V ST60L254** has fallen to **$155.39** from a $219.99 list — a 16-inch swath, 0.095" line, 68 dB and a 4-year tool-and-battery warranty, kit-complete with a 2.5 Ah battery and charger — and is now the best value in the table [src5, src6]. The **WORX WG163** at **$84.99** ships with two 20V batteries and a charger at 5.5 lbs [src5, src6]. The **EGO ST1623T** at **$299** (down from a $359 list) is the best kit-complete all-rounder, pairing LINE IQ auto-feed with POWERLOAD winding and up to 60 minutes on its 4.0 Ah battery [src1, src2]. Two picks moved the wrong way: the **Husqvarna 320iL** is back to **$319** now that its spring discount has ended, and the **EGO ST1521S** Amazon buy box has jumped to **$446.99** while EGO's own product page lists the SKU as "Coming Soon" — treat that one as supply-constrained, not as a buy [src10]. Platform owners should stay in their ecosystem: the Milwaukee M18 FUEL 3046 ($318.93 kit) and DeWalt DCST972X1 ($319.99 kit) are the M18 and FlexVolt answers [src1, src2, src4].

## Best for Each Use Case

### Best-Tested Homeowner Tool: Ryobi RY402110 40V HP Whisper ($223, tool only) — [Check price](https://knowledgelib.io/go/ryobi-ry402110)
The 2026 shootout winner in Pro Tool Reviews' homeowner category, scoring 90 points. The 40V HP brushless motor drives a 17-inch cutting swath that handles 0.105" line — usually pro-tier territory — measured at 5,621 RPM and 13.3 lbs as tested. Whisper Series carbon fiber shaft; Ryobi's own marketing claims 72% quieter than gas and more power than a 30cc gas engine (manufacturer claim, not independently measured). EXPAND-IT compatibility extends it to 40+ attachments. **Configuration warning: the $223 Amazon listing is the TOOL-ONLY SKU — no battery, no charger.** The kit is the RY402110VNM with a 6.0 Ah battery and rapid charger; Pro Tool Reviews prices the pair at $249 bare / $329 kit, so budget roughly $80 more at MSRP (more if you buy a 6.0 Ah HP battery and charger separately). RYOBI is a Home Depot house brand, so its own retail channel is homedepot.com and ryobitools.com; Amazon listings are marketplace inventory. [src1, src2]

### Best Kit-Complete All-Rounder: EGO ST1623T Line IQ ($299 kit, 4.0 Ah + charger) — [Check price](https://knowledgelib.io/go/ego-st1623t)
The EGO ST1623T finished a close second at 86 points in Pro Tool Reviews' 2026 shootout and leads on "set-and-forget" convenience: LINE IQ auto-sensing line feed and POWERLOAD automatic line winding eliminate the most frustrating aspects of trimmer maintenance. 16-inch cutting swath, telescopic carbon fiber shaft with lifetime warranty, IPX4 weather resistance, and up to 60 minutes of runtime on the included 4.0 Ah battery under light-to-moderate trimming. Now $299 against a $359 list. Because it ships kit-complete, it is the cheaper real-world buy than the $223 tool-only Ryobi for anyone with no 40V batteries. [src1, src2, src5]

### Best Attachment Value: Ryobi RY40290 ($209.99 kit, 4.0 Ah + charger) — [Check price](https://knowledgelib.io/go/ryobi-ry40290)
The RY40290 still delivers strong bang-for-buck below the HP flagship: 40V brushless motor, lightweight carbon fiber shaft, REEL EASY+ bump-feed head that reloads in under 60 seconds, and a 4.0 Ah battery + 90-minute charger in the box. Adjustable 13-15 inch cutting width trades runtime for productivity, running 0.080" line. EXPAND-IT attachment compatibility (edger, pole saw, blower) — and it also accepts universal gas-style attachments — extends its value further. Lawn Love still ranks it their Best Overall battery-powered trimmer. [src1, src6, src7, src8]

### Best Multi-Head System: Skil PWRCore 40 PLT1500C-10 ($219 kit, 4.0 Ah + charger) — [Check price](https://knowledgelib.io/go/skil-plt1500c-10)
A 40V brushless power head sold as a kit with the 16-inch trimmer attachment, a 4.0 Ah PWR CORE 40 battery and an Auto PWR JUMP charger. The trimmer head cuts at 14" or 16" (reverse the guard's line cutter to drop to 14" for tight work) on 0.080" dual line with a Twist Load head. SKIL states the head is for use with its own Multi-Head System and with universal attachment-compatible power heads — verify fit before buying a non-SKIL attachment rather than assuming it. Sold on its own the trimmer attachment lists at $109.99, so the kit is the sensible entry point. [src5, src6]

### Best for Large Yards and Heavy Brush: DeWalt DCST972X1 ($319.99 kit, 9.0 Ah + charger) — [Check price](https://knowledgelib.io/go/dewalt-dcst972x1)
The DeWalt DCST972X1 pairs a 60V FlexVolt brushless motor with an adjustable 15/17-inch swath — the widest in the homeowner tier — running 0.080" dual line and accepting DeWalt 0.095" line for tougher growth. Variable trigger plus hi/lo speed control lets you trade power for runtime. The 9.0 Ah FlexVolt battery is backward-compatible with DeWalt's 20V MAX tools, making it the obvious pick for anyone already in the DeWalt ecosystem. Universal attachment capability (edger, brush cutter, pole saw, hedge trimmer, blower) adds versatility for larger properties. Pro Tool Reviews prices it at $289 bare / $369 kit, so the $319.99 Amazon kit is a genuine discount. [src1, src2, src4]

### Best for Professionals: Husqvarna 525iLST (tool only, dealer-set price) — [Check price](https://knowledgelib.io/go/husqvarna-525ilst)
The 2026 professional category winner at 93 points. Husqvarna's 40V BLi-X pro battery system, an 18.1-inch cutting swath (largest in the comparison), 0.105" line capability, and a T35X M10 trimmer head included. Husqvarna rates it at up to 7,200 RPM; Pro Tool Reviews measured 5,490 RPM under load and 13.1 lbs as tested, against a bare-tool weight of 8.82 lbs. Compatible with the BLi200, BLi300 and BLi950X batteries — the BLi950X backpack battery is what enables a full crew day of cutting. **Battery, charger, harness and blades are not included, and Husqvarna publishes no price on its own product page: this is a dealer-channel product, so you buy it from a Husqvarna dealer rather than online.** Pro Tool Reviews lists a $429.99 street price for the bare tool; a BLi-X battery and charger add several hundred dollars more on top. Budget for the dealer visit as a real friction cost. [src1, src9]

### Pro Alternative: Milwaukee M18 FUEL 3046 ($318.93 kit) — [Check price](https://knowledgelib.io/go/milwaukee-3046-21hd)
For tradespeople already on the M18 platform, Milwaukee's POWERSTATE brushless motor is rated at 1.76 HP — Milwaukee's own comparison is to a 31cc gas engine, a marketing claim rather than a measured test — with a variable speed trigger offering three speed settings up to 6,200 RPM. Adjustable 14-16 inch cutting swath, Easy Load trimmer head (reloads 20 feet of 0.095" line in under 30 seconds), and the QUIK-LOK attachment system. At 9.9 lbs bare it is surprisingly manageable, though that is the bare-tool figure — an M18 HIGH OUTPUT 8.0-12.0 Ah pack adds meaningful weight. This ASIN is the Quik-Lok KIT. The M18 platform's 200+ tools is the main draw; buy the bare 3046-20 instead if you already own M18 packs. [src1, src2]

### Best Dual-Direction Cut: Husqvarna 320iL ($319 kit, 4.0 Ah + charger) — [Check price](https://knowledgelib.io/go/husqvarna-320il)
A standout residential option from a heritage brand, though its spring discount has ended and it is back to $319 — up from the ~$200 it was running in June. 16-inch cutting swath on 0.095" line, straight shaft, brushless motor with active cooling, and a dual-direction line rotation that switches which way clippings throw — useful for keeping debris off paths or your shoes. 10.1 lbs with the 4.0 Ah battery fitted, plus a "boost" button for 20% more power in thick weeds. Husqvarna recommends it for 1/2-1 acre yards. The Rapid Replace head simplifies line changes. Unlike the pro 525iLST, this one is sold on Amazon. [src2]

### Best Value: Greenworks 60V ST60L254 ($155.39 kit, 2.5 Ah + charger) — [Check price](https://knowledgelib.io/go/greenworks-60v-st60l254)
Down from a $219.99 list to $155.39, this is the cheapest way into a full 16-inch, 60V, kit-complete trimmer. Greenworks claims power equivalent to a 26cc gas trimmer (a manufacturer claim) and about 53 minutes of runtime — measured on the included 2.5 Ah battery under moderate trimming, so expect materially less in heavy growth. A Spin-to-Load head reloads 0.095" line without manual winding, it runs at 68 dB, and the 2.5 Ah pack recharges in 45 minutes. The 4-year warranty covering both tool and battery is unusually long at this price, and the 60V pack powers 75+ other Greenworks tools. 11.2 lbs with the battery fitted. [src5, src6]

### Best Budget and Lightest: WORX WG163 ($84.99 kit, two 20V batteries + charger) — [Check price](https://knowledgelib.io/go/worx-wg163)
At 5.5 pounds the WORX WG163 is the lightest full-featured cordless trimmer here, and at $84.99 (from a $119.99 list) the cheapest. Its 20V PowerShare battery system is compatible with WORX 20V and 40V tools, and the head tilts 90 degrees to convert from trimmer to edger, with rubberised wheels to guide the edge. Two 20V batteries and a charger are in the box. Specs are modest and honestly so: a 12-inch cutting diameter on thin 0.065" line at 7,600 RPM no-load. That is a small-yard, light-growth tool — it will bind in thick weeds. [src5, src6]

### Skip at This Price: EGO ST1521S ($446.99 kit) — [Check price](https://knowledgelib.io/go/ego-st1521s)
The ST1521S is a good trimmer — POWERLOAD winds the line at a button press, the carbon fiber split shaft folds for storage and carries a lifetime warranty when registered within 90 days, the tool has a 5-year warranty, and it cuts 15 inches on 0.095" line at 9.9 lbs. But the Amazon buy box is currently **$446.99**, roughly 80% above the ~$249 this SKU normally sells for, and EGO's own product page lists the ST1521S as "Coming Soon" and unavailable, alongside sibling configurations (ST1520S bare tool, ST1523S with a 4.0 Ah pack, ST1524 with 5.0 Ah). That combination reads as a SKU in transition with constrained marketplace supply. At today's price the ST1623T is more trimmer for $148 less — buy that instead, or wait for the ST1521S to return to normal pricing. [src2, src5, src10]

## Head-to-Head Comparisons

### Ryobi RY402110 vs EGO ST1623T
The like-for-like comparison people get wrong. Pro Tool Reviews' 2026 homeowner shootout scored Ryobi 90 to EGO's 86: the RY402110 has a wider cut (17" vs 16"), takes heavier 0.105" line, and the carbon-fiber Whisper shaft is quieter. But the $223 Ryobi listing is TOOL ONLY and the $299 EGO is a full kit with a 4.0 Ah battery and charger, so the EGO is the cheaper working trimmer today. EGO also wins on convenience: LINE IQ auto-feeds line as it wears, POWERLOAD winds line at a button press, and the lifetime-warranty shaft beats Ryobi's 5-year tool warranty. [src1, src2]
**Pick the Ryobi if:** you already own Ryobi 40V batteries and have ≥1/2 acre or thick weeds — 0.105" line on a 17" swath cuts faster. **Pick the EGO if:** you own no batteries yet, or you hate dealing with line.

### Ryobi RY402110 vs DeWalt DCST972X1
Both reach a 17" cutting swath. On sticker the Ryobi looks $97 cheaper, but that compares a bare tool against a kit with a 9.0 Ah FlexVolt battery and charger — add a Ryobi 6.0 Ah pack and charger and the DeWalt is the better-equipped buy. RY402110 is lighter as tested (13.3 vs 13.5 lbs) and takes heavier 0.105" line; DCST972X1 runs 0.080" dual line (or DeWalt 0.095"), has hi/lo speed control, and its FlexVolt pack also runs DeWalt's 20V MAX tools. [src1, src2]
**Pick the Ryobi if:** you are already on Ryobi 40V and want the heavier line. **Pick the DeWalt if:** you own DeWalt batteries, need brush-cutting heft, or want a kit rather than a bare tool.

### Greenworks ST60L254 vs Skil PLT1500C-10
The two value kits, $63.61 apart. Greenworks gives you more trimmer for less money: 60V, a full 16" swath on 0.095" line, 68 dB, and a 4-year warranty on tool and battery, kit-complete at $155.39 — but only a 2.5 Ah pack, and it is a single-purpose trimmer. Skil at $219 is a 40V multi-head power head that also takes other attachments, ships a larger 4.0 Ah battery and an Auto PWR JUMP charger, but cuts 14-16" on thinner 0.080" line. [src5, src6]
**Pick the Greenworks if:** you want the most cutting power per dollar and only need a trimmer. **Pick the Skil if:** you want one battery and one power head to also drive an edger, pole saw or blower later.

### Skil PLT1500C-10 vs Ryobi RY40290
Both are sub-$225 attachment-capable 40V kits with a 4.0 Ah battery and charger. Ryobi is $9 cheaper, plugs into the larger first-party EXPAND-IT catalog (40+ attachments) and also accepts universal gas-style attachments, with a carbon fiber shaft and a REEL EASY+ bump head; its 13-15" swath is the narrower of the two. Skil cuts 14-16" and its power head is designed for SKIL's Multi-Head System plus universal attachment-compatible heads — check fit per attachment rather than assuming cross-brand compatibility. [src5, src6, src7]
**Pick the Skil if:** you want the wider swath and are buying SKIL attachments. **Pick the Ryobi if:** you want the biggest first-party attachment catalog or already own Ryobi 40V packs.

### Husqvarna 525iLST vs Greenworks Commercial ST161
Both are professional TOOL-ONLY picks targeting daily crew use, and neither price includes a battery. The 525iLST won the 2026 shootout pro category at 93 points with an 18.1" swath, 0.105" line and 5,490 measured RPM, plus the BLi950X backpack-battery option for full-day runtime; Pro Tool Reviews lists it at $429.99 bare. The Greenworks Commercial ST161 scored 87 with a 17" swath on 0.095" line, weighs 16.2 lbs, and is listed at $599.99 bare / $649.99 kit — so it is actually the more expensive entry, not the cheaper one. [src1]
**Pick the Husqvarna if:** you need the widest swath, the heaviest line and backpack-battery runtime, and you are willing to buy through a dealer. **Pick the Greenworks Commercial if:** you want a kit price published online and a supplier who will sell you one without a dealer visit.

## Decision Logic

<!-- Structured if-then rules for agent decision-making. Data-backed, specific to this category. -->

### If you own no batteries yet
--> Buy a KIT, not a bare tool, and compare kit prices only. The kit rows here are the WORX WG163 ($84.99), Greenworks ST60L254 ($155.39), Ryobi RY40290 ($209.99), Skil PLT1500C-10 ($219), EGO ST1623T ($299), Milwaukee 3046 ($318.93), Husqvarna 320iL ($319) and DeWalt DCST972X1 ($319.99). The RY402110 ($223) and Husqvarna 525iLST are tool-only and cost more than their sticker suggests. [src1, src5, src6]

### If budget < $100
--> Get the WORX WG163 ($84.99 kit with two 20V batteries and a charger). It is the only sub-$100 pick here and adds 2-in-1 trimmer/edger functionality, but accept its limits: 12" swath on 0.065" line and 5.5 lbs, which suits small yards and light growth, not thick weeds. [src5, src6]

### If budget is $150-$225 and value is the priority
--> The Greenworks 60V ST60L254 ($155.39 kit) is the most cutting power per dollar: 60V, 16" swath, 0.095" line, 68 dB, 4-year tool-and-battery warranty. Step up to the Ryobi RY40290 ($209.99 kit) or Skil PLT1500C-10 ($219 kit) only if you want an attachment-capable power head rather than a trimmer alone. [src5, src6, src7]

### If user already owns batteries from a specific brand
--> Stay in the ecosystem and buy the bare tool. Ryobi 40V: the RY402110 Amazon listing at $223 IS the bare tool, which is exactly what you want here. Others: DeWalt FlexVolt DCST972B, Milwaukee M18 3046-20, EGO 56V ST1620T/ST1521S bare, Husqvarna BLi-X 525iLST (dealer). Pro Tool Reviews' bare-vs-kit spreads run roughly $80 on the Ryobi ($249 vs $329) and $80 on the DeWalt ($289 vs $369), so the saving is real but smaller than the "battery costs $150" rule of thumb suggests. [src1, src2]

### If yard is over 1/2 acre
--> Take the widest swath you can afford, kit-complete: EGO ST1623T ($299, 16", up to 60 min on 4.0 Ah) or DeWalt DCST972X1 ($319.99, 15/17", 9.0 Ah). If you are already on Ryobi 40V, the bare RY402110 ($223, 17", 0.105" line) is the best-tested option. Avoid 20V systems at this yard size. [src1, src2, src7]

### If primary use is edging driveways and walkways
--> The WORX WG163 converts to a wheeled edger by tilting the head 90 degrees and is the purpose-built answer. The Ryobi RY40290 and RY402110 accept an EXPAND-IT edger attachment, as does the Skil PLT1500 power head. The Husqvarna 320iL's dual-direction switch throws clippings away from the paved surface you are edging. [src2, src5, src6]

### If user needs to clear heavy overgrowth or brush
--> Choose on line diameter, not on horsepower marketing: Ryobi RY402110 and Husqvarna 525iLST take 0.105" line, DeWalt DCST972X1 and Milwaukee 3046 run 0.095". All accept brush-cutter attachments for woody stems. Avoid the WORX WG163 (0.065") and anything on 20V — they bind on thick vegetation. Expect heavy line to cut runtime by 20-30%. [src1, src4]

### If use is professional / daily commercial
--> The Husqvarna 525iLST (2026 shootout pro winner, 18.1", 0.105" line, ~$429.99 bare) paired with a BLi950X backpack battery, or the ECHO DSRM-2600 ($499.99 bare / $619.99 kit) or Greenworks Commercial ST161 ($599.99 bare / $649.99 kit). Factor the channel in: the Husqvarna is dealer-only with no published online price, while the Greenworks and ECHO kit prices are public. [src1, src9]

### If the recommendation must survive a price check
--> Do not recommend the EGO ST1521S right now. Its Amazon buy box is $446.99 against a normal ~$249, and EGO's own site lists the SKU as "Coming Soon" and unavailable. The ST1623T at $299 is a better trimmer for less. [src10]

### Default recommendation
--> For an unknown homeowner with no existing battery platform, the EGO ST1623T ($299 kit) is the safest pick: it ships complete with a 4.0 Ah battery and charger, LINE IQ and POWERLOAD remove the most-hated part of trimmer ownership, and it scored 86 in the 2026 shootout — second only to a tool-only Ryobi. If budget is the binding constraint, the Greenworks ST60L254 at $155.39 is the value answer; if the user already owns Ryobi 40V packs, the bare RY402110 at $223 is the best-tested tool in the comparison. [src1, src2, src5]

## Key Market Trends (2026)

- **The kit-vs-bare-tool split is now the biggest pricing trap in the category**: the same model can appear at a 40-50% price gap depending on which SKU a retailer lists, and Amazon titles frequently omit the distinction. Pro Tool Reviews' own spreads — Ryobi RY402110 $249 bare / $329 kit, DeWalt DCST972 $289 bare / $369 kit, ECHO DSRM-2600 $499.99 / $619.99, Greenworks ST161 $599.99 / $649.99 — show the pattern across the whole tier. Always confirm the configuration before comparing two prices. [src1]
- **17-inch swath at the homeowner price point**: Pro-tier 17-inch cutting widths (previously $400+ commercial-only) now appear on sub-$330 homeowner flagships — Ryobi RY402110, DeWalt DCST972, and Milwaukee 3046 all reach 16-17". The 12-15" mid-tier is being squeezed. [src1, src2, src7]
- **0.105" line moves down-market**: Heavy 0.105" trimmer line — once exclusive to commercial trimmers — now runs on the Ryobi RY402110 and Husqvarna 525iLST. Heavier line clears brush and woody stems faster but reduces runtime by 20-30%. [src1]
- **"Quiet" branding becomes a tier**: Ryobi's Whisper Series and Husqvarna's brushless designs now market noise reductions (Ryobi claims 72% quieter than gas for the Whisper line). Greenworks 60V publishes 68 dB. These are the few published figures in a category that mostly does not quote decibels — Pro Tool Reviews' 2026 shootout published no dB measurements at all. [src1, src5]
- **Battery parity with gas**: More than 90% of battery trimmers now score above-average in both trimming and edging tests, matching or beating gas models in daily performance while eliminating fuel mixing, pull-start failures, and engine maintenance. [src3]
- **Auto-feed line technology maturing**: EGO's LINE IQ (auto-sensing line feed) and POWERLOAD (automatic winding) represent the next generation of trimmer heads. Milwaukee's Easy Load head, Ryobi's REEL EASY+, and Husqvarna's Rapid Replace are competing approaches. The "automatic" battle has become a primary purchase driver. [src1, src2]
- **Carbon fiber shafts becoming standard**: Previously a premium feature, carbon fiber shafts now appear on mid-range models like the Ryobi RY40290 and Whisper Series. They reduce weight by 15-25% versus aluminum while increasing durability and reducing vibration. [src1, src6]
- **Platform lock-in intensifying**: Every major brand now offers 50-200+ tools on a shared battery platform. Battery investment increasingly drives trimmer choice, making first-tool purchases strategically important. [src2, src7]
- **Backpack batteries unlock pro adoption**: Husqvarna's BLi950X and ECHO's 56V backpack systems now enable a full crew day of trimming on battery — the last barrier to commercial cordless adoption. [src1]

## Important Caveats

- **Kit vs tool only**: the RYOBI RY402110 ($223) and Husqvarna 525iLST are TOOL-ONLY at their quoted prices — no battery, no charger. Every other row is a kit. Do not compare a tool-only price against a kit price
- **The EGO ST1521S row is a live price, not a recommendation**: $446.99 is roughly 80% above what this SKU normally sells for, and EGO's own site currently lists it as "Coming Soon" and unavailable. It is in the table because the buy_link resolves to it, and it is flagged rather than removed
- Prices are US Amazon prices fetched on 2026-08-05 and fluctuate seasonally; late-summer clearance (Greenworks −29%, WORX −29%, EGO ST1623T −17% off list) is why several kits are cheaper now than in June
- Manufacturer-quoted runtimes assume moderate load with the specific battery named; heavy weeds with 0.095" or 0.105" line can reduce runtime by 30-50%, and the 2.5 Ah kits (Greenworks, EGO ST1521S) run roughly half as long as their 5.0 Ah siblings
- Gas-equivalence claims (Greenworks "26cc", Ryobi "30cc", Milwaukee "1.76 HP / 31cc") come from the manufacturers' own marketing and were not independently measured by any source cited here
- Weight is listed with the battery installed except where noted (Milwaukee 9.9 lbs and Husqvarna 8.82 lbs are bare-tool figures); bare-tool weights typically run 2-4 lbs lighter
- Husqvarna sells the 525iLST through dealers and publishes no price on its own product page — the ~$429.99 figure is Pro Tool Reviews' street price for the bare tool, and your dealer's may differ
- RYOBI is a Home Depot house brand; its own retail channel is homedepot.com and ryobitools.com, and Amazon listings are marketplace inventory whose price and configuration can drift from the brand's
- Consumer Reports model scores are behind a paywall — specific scores could not be independently verified beyond their published recommendations
- Attachment compatibility varies: Ryobi EXPAND-IT and SKIL Multi-Head both claim compatibility with universal attachment-capable heads, but verify fit per attachment rather than assuming cross-brand interchange
- The Pro Tool Reviews 2026 shootout (published 18 March 2026) used a single test session per model and did not test the Skil, WORX, Greenworks ST60L254 or Husqvarna 320iL; long-term durability rankings can differ, and Reviewed's guide (src4) has not been updated since March 2025
