- Reviewed in Canada on August 2, 2023Verified PurchaseI am very happy with this weed whacker :-)
For years I've made do with cheapo plug-in weed whackers picked up at yard sales and hey, they've done the job ok. Now I needed one i could take further than a cable would reach so bought one of these and now am wishing I'd got one years ago !
This thing is a "weed terminator", it goes through just about everything. It has munched through brambles, even small maple branches. Super easy to use. I've been using a pair of 5Ah batteries with it, I'm generally having to swap the first one out if it is more than a quick job, but haven't gone through both of them yet.
Downsides - It is a little on the heavy side, but it is pretty solid. I switch holding it from one side to the other intermittently. It isn't so heavy that I'm forced to take a break though. I will probably try and rig up a shoulder sling to take some of the weight. With brambles and vines, it will sometimes get them wrapped around just above the cutting head which makes it halt. It is easy though to turn it upside down and pull them off.
Tip - it comes pre-loaded with cord, but not much of it. If you like it on the first use I'd suggest buying/ordering more cord straight away.
Overall, I am very happy with this tool and very impressed with what it can do. I would recommend this.

- Reviewed in Canada on June 27, 2025Verified PurchaseI replaced my gas weed eater with this one. Hard to give up the gas one because you can cut down a small tree with it. The DEWALT one lived up to its name! It’s relatively quiet and will cut through the thick stuff with ease! I haven’t had to mess with the string yet either. That was a constant thing with my other one.
- Reviewed in Canada on July 19, 2025Verified PurchaseNot quite sure about the trimmer head noise...sounds like a bearing starting to fail at low rpm especially when winding down. Not sure if this is normal or a problem waiting to happen.
Unit functions well and has more than enough power.

5.0 out of 5 stars some care and usage tips after 1.5y solid runtime
Verified Purchasebefore I start, it's 5 stars from me - love this unit and I'm returning right now to buy a replacement. More on that below. Included some photos so you can see how the gunk will build inside the unit - gunk can build up exactly where the motor tries to breath! So I did my very best addressing this with some tips below.
some care and usage tips after 1.5y solid runtime:
- regularly CLEAN THE VENT HOLES for the motor at the head of the unit - it needs to breath. Use Qtips, for example, and perform these maintenances before or after EVERY RUN to keep the gunk from getting "pushed" in further by more gunk.
- Edit: Turns out a WIRE BRUSH is enough 99% of the time. QTips not needed. I've been doing it *before* runs when the gunk buildup is dry. When I look into the vent holes, I can see this is doing a good job. Convenient, fast, and easy to do.
- Mind that these small vent holes (at the top of the motorhead) are AIR INTAKES - so they attract material into the holes via negative air pressure (ie. slight vacuum). The larger holes below are exhausts - don't need to worry about those, they don't collect gunk buildup because they blow air out.
- the vacuum effect is not too big of a problem, by the way - the intake vent hole vacuum isn't that strong. You could go 3 heavy runs without the vents getting too clogged - just depends on the nature of the runs. Just have to keep an eye on it, and have to consider running a wirebrush over it before every run - that's a good and easy maintenance.
- the motor on this unit is down at the end of the pole, for that reason you might want to STICK TO DRY CONDITIONS with this unit
- DO NOT WASH the head of the unit with water - use a wire brush
- avoid sweeping the tool deep in bunches or piles of cuttings or other material (such as grass you just cut, where you want to make a 2nd, lower sweep to cut farther down) - that is a source of the "gunk" that can get in the vent holes.
- combining the logic of some advice above: EVENING HOURS when its both dry and cooler are the best times to make runs.
- as you would expect, this brushless motor can BURN OUT if you really push it.
--- take some breaks especially during the hottest days
--- don't just swap 5AH batteries in back-to-back without letting that motor cool off some
--- sometimes the batteries get hot, and will prevent the unit from running - THATS GOOD (if annoying sometimes) - now listen: we can prevent the battery from making this decision by simply holding the trigger for a long time. THATS BAD, DONT DO THAT. LET THE UNIT REST. If the battery does this, and you feel like the motor shouldn't be running too hot (ie. you've been keeping gunk from the vent holes, ambient temp is avg or low, etc), then *maybe* it's an OK time to swap batteries just for a bit so you can keep working - the batteries do heat up faster than the motor.
EDIT: I read that the motor also has heat sensors which will prevent the unit from running. In that case, it seems the point stands:
- *Do* regularly let off the trigger to see if the unit wants to take a break.
- just saying it one last time... It seems very important that the vent holes remain unobstructed by gunk, to help the motor stay cool.
- It also seems that operators in more humid climates should take extra care, because very dry material, or conditions, won't lead to "gunking up" in the vent holes as deleteriously - although, plants generally are wet when cut. Apply discretion.
- Dewalt probably wouldn't recommend this, but after maybe 1y of solid use, you might open it up to get Qtips farther in and keep the passageways unobstructed. Note: start unscrewing from the head back - the neck doesn't need unscrewed.
- dont forget the high/low setting. Low will generate less heat, and low does great work when set against "easier targets". On the same token, if you use low against heavier targets, you'll end up running longer trying to wear the targets down, and it'll make more of a mess which means more gunk to obstruct the vent holes, and negate the efficiency of using low - so HIGH is better against those targets. EDIT: I've been just running on "low" lately with the new unit, and using dewalt's own .08 string .. why did I ever do anything different? Just run on low with their .08 string, it works great. The string is small and "cuts".
- going to recommend sticking with dewalt's advice to only run their .08 line - that is what it is designed for and the longevity of the motor should take priority over the reasoning for using different string
- not 100% sure on this, but I imagine (and from experience it does seem like) allowing the string out more often toward the 14" radius will help with many of the points above. The string travels at a higher MPH out farther from the head, cuts better, and the cuts are creating gunk at more of a distance from the motor. So that sounds like win-win right? I suppose so. EDIT: the string length does make the motor work a lil harder. Apply your own discretion.
My situation:
I let the head's vent holes get a bit cloggy and now I'm back to buy a 2nd unit (because I like this product so much). Basically I burned the motor out by running on high setting for 2 entire 5AH charges back-to-back (yes, I violated all my tips above) and it just died and wont start now. Dewalt does offer a "fixed in $79" guarantee via their website, but I figure after taxes and buying packing and everything I'd be out $110. So why not pay the extra $50 and get a brand new one. Won't be making the same mistake again. Might also be more careful about banging it to draw the string out ... don't want to bang it too hard - that trimmer head has electrical board & wiring in it! Not that I ever abused the unit too much ... or so I thought. Anyway, $160 for 1.5y of using this unit, for how light and convenient it is, and how quiet it is, and considering how much I used it, and the heavy jobs I set it on ... I'm too enamored to go without it, and getting a replacement.

5.0 out of 5 stars Surprised, in a good way
Verified PurchaseNot a professional, but this thing is a beast compared to my B&D 20v. I certainly don't have much to compare, but if there are more powerful options out there I'd be shocked. I can't imagine needing to up it to fast speed. Trimming, edging, just cuts it all down.
I was a little worried about the .80 string, but it works well for me.
I used a 4 AH battery, trimmed and edge around my house, still showing 3 all the bars. So, it must not use a lot of juice.
Definitely surprised (in a good way) with my purchase.
Just one negative. The shield doesn't guard from debris very well. I got hit with a lot of stuff. Long pants are probably a requirement (didn't have that with my old string trimmer).
