works good
I got this for my wife because she had trouble starting my gas trimmer. This is easy to run and has more power than I expected.

not for landscaping no interchangeable attachments
I have several 60v tools so I thought I’d give this one a try. When I opened the box I was very disappointed and should have returned it right then. It’s obvious it was only designed to fit in that shipping box and not designed for yard work. Let’s start with the folded shaft. I thought I would have future tools adaptable to the trimmer like every other trimmer that comes with a two piece shaft . Wrong. It’s equipped with a weak spot that’s all, the shaft is not really two pieces, there is a solid wire running thru the shaft that can not be disconnected to separate the two parts making it more difficult to transport when separated. Next the shield might just as well not even be there. I’m used to trimming in shorts and a t-shirt. With the dewalt no matter how you use it your getting covered in debris, my legs were bleeding the first time I used it and thankfully I wear glasses! I’m sure that tiny shield was designed just to fit in the shipping box as well. The trimmer head sucks! Replacing string should not be so complicated! Why dewalt did not use the industry standard (M10x1.25 LH) trimmer head is truly baffling. I was not impressed with run time like other reviewers claim. A tank of gas lasts easily more than twice as long as a fully charged 60v battery. This tool would not be a good fit for a professional landscaper. I will say the trimmer had plenty of power when the battery was fully charged.
Don’t waste your money on this tool. I’m used to running quality trimmers like stihl and husqvarna, I purchased the dewalt to try and get away from the vibration of the gas motor, but the dewalt has plenty of vibration of its own and the lack of a proper shield and the difficulty of reloading the string make this tool miserable to use. The battery is also not easy to remove from the trimmer. It’s obvious the engineers who designed this tool do not cut their own lawn! Last but not least Dewalt says you can not use this trimmer to define the edge of anything, the manual states; "Keep the rotating string roughly parallel with the ground (tilted no more than 30 degrees)." WHO uses their string trimmer and does not define the edges they worked so hard to put in the landscape or to quickly touch up the edge of a sidewalk or driveway?

Avid Do-it-Yourselfer
Good, but needs work out of the box!
Power: It's got plenty! I'm cutting a 1-acre yard and a 9 acre business lot with a lot of pasture land, and this thing will chew through everything I throw at it with no problem, so that's a plus! It has two speeds, but I've not yet found anything I needed hi-speed for. The low-speed is 5000 RPM and the high is 6000 RPM. Low will do probably 99% what you need from it.

Comfort: I personally find it very well balanced, but if you need to adjust the forward grip for your height or arms, you certainly can. It's not hard to do at all. It's quiet compared to my gas trimmers so I love that! No more fuel-oil mixes to worry with! No more carbs being replaced in my Stihl. I'm done with that!

Battery: I might edit this later, but so far I've found the battery to be fine. In case you're confused, this is a flexvolt 60V battery, so if you're using it in your Dewalt weed trimmer, it's running at 60V so it's a 3AH battery. If you're running it in your 20V tools (like handheld drills, fans, saws, etc) then it's a 9AH battery, which means it would run deck screws all day long on one charge. It should holdup fine for most anyone I'd imagine.

Charger: It comes with the generic 20v charger every Dewalt tool comes with. If you need to fully-charge it, it's going to take a couple hours... somewhere between 3-5. If you really need the fast-charging, you can get the fast charger and folks say it can full-charge in about an hour. I just bought another battery, so I'm fine with the normal charger. Yes, you can use any of the other 20v lithium chargers from any of your other Dewalt tools to charge it - just in case you're curious.

Trimmer Guard:
So this was the first negative thing I noticed. This trimmer is going to throw mess ALL OVER YOU the moment you fire it up. You're going to be covered in debris from head to foot! This guard sucks. The funny thing is, Dewalt sells a much wider guard for about $6.20 on their website. The part number is: N512929 and you can find it here:
(Shipping will run you $12, but it's still worth it).

This trimmer comes with 25' of the 0.08" Dewalt string on it. I burned through that like a hot knife through butter. I replaced it with the standard 0.095" thicker string I usually use and it's worked like my gas one does - much better. So my advice, if you have a lot of concrete to edge or fence posts, run a larger string on it. If you're not edging, then you won't care but if you're not edging something then you likely wouldn't need a weed wacker anyway, right?

Trimmer Head:
So I tried to give this thing the benefit of the doubt and just assumed I was an idiot, until I started reading other reviews. So listen to everyone else on here and believe me when I tell you this trimmer head is total bunk! You can get a replacement Husqvarna T35 for about $13 on Amazon, which is what I did. If you need to figure out how to attach it, simply read the manual. You just pop a small screwdriver in the slot on the side, turn it until it slides in all the way, then turn the head CLOCKWISE to take it off (it's reverse threaded), and screw the new one on.

The issue with the head is that Dewalt really dropped the ball on the assembly of the string head. It's a pain to feed new string through the holes in the head and still be sure you don't get it coming off the spool. When it does come off the spool, it ties up around the spindle and then won't feed when you bump it. When it happened to me once, I figured I was the idiot. When it happened twice in 4 hours, and then again 5 minutes later, I ordered the new head. I'm not dealing with that mess all summer and neither should you.

All said and done, I still think the unit is amazing. It's got two problems and both of them are around $10 to replace with better parts. I wish they would make the larger guard standard and fix the head, but I'd still buy it again if I had to do it again. Totally worth the slight effort it takes to take it from "pretty good " to "great".

I have had this for a month now and couldn't be happier. I trim around my house and garage Then I do my parents property that has a lot of trimming. I love this thing, it starts every time. I am also a contractor that has a Dewalt cordless tools. When I checked the price of the trimmer and seen the battery that was included, I realized I was buying a battery and a charger with a free tool. I figured that if the trimmer doesn't hold up at least i got a good battery for my saw. The trimmer seems like it should last, I just wish the guard was a little wider and it came with a strap

Runs much longer than anticipated
I bought this bad mamma-jamma last year and so far I get about 3 trimmings per battery charge which I find to be mighty impressive. Coolest part about weed-wacking for the first time this spring might you ask? Literally pick it up and go trim. No fueling issues or pulling a starter cord. Also this sucker is quiet, you can still wear your headphones to rock out but you can also hear things/vehicles sneaking up on you - one may say it could be a safety component.

Gas like power!
I bought this trimmer to get into the flexvolt line and I must say this trimmer has so much power. It comes with a standard .080 line, it does a good job with that line but I swapped it out for a .090 and noticed a huge difference in performance and durability. It eats through the weeds like a hot knife through butter. Well-balanced, just 15 pounds, battery life is great and that’s why I got into this platform because I can use the Flexvolt battery with my current DeWalt tools including my Flexvolt blower and 2x20 lawnmower which both items are great. Don’t care what people think about the lawn mower, it makes my job so much easier compared to the gas mower I had a year ago. Thank you Dewalt.

Good weight. Good power. Balanced well. The only negative is the ridiculously small guard that comes with it. Not sure what they were thinking but there is so much stuff that shoots back at you while trimming.

CAN I say I wish it had less power? It’s a hoss. I wish it held unlimited line. Only complaints I have! DeWalt hit the nail on the head with this one! Great tool!

Was skeptical to try a battery operated weed eater instead of purchasing a gas model, but after reading reviews on the DeWalt decided to try this model. Plenty of power to last trimming 2/3 acre residential property still had a full charge on the battery. Had no problem with string getting tangled or breaking off in the head, with the best approach is to go slowly in order to get a good feel for the performance and adjustment from gas to electric.
