I wished I had gotten a charger and batteries with the trimmer. I used the batteries that I already have. It works okay as far as the batteries I already have as far as battery charge. What I don’t like is the weight. It’s heavy considering it’s 7.5lbs. Performance wise it’s good. Does what it’s supposed to do. Line feeds good. It’s just the weight. It folds so it stores well.

Tool works great and cuts through grass well on the LO speed setting. I've covered about 1,000 square feet of grass on the first day and it works great! I've only had to use the HI speed on tough grass. This trimmer also eats through batteries like no ones business, and I definitely recommend buying the tool and battery combo, with the proper XR battery. I drained two four amp hour and one two amp hour normal 20 volt Max batteries before I ran out of the 20 feet of trimmer line, so I definitely recommend the XR battery or the new Powerpack for this trimmer for long hard jobs! Overall, amazing tool, and lighter then my old gasoline trimmer, I can use this all day... apart from battery swaps.

I love this weed eater. I’m coming from a craftsman 60 volt that i also loved but the battery took a crap and they are no longer made. Before purchasing the dewalt i bought a Greenworks 17” 40 volt that came with an 8ah battery. I bought the Greenworks specifically because it was the only cordless electric steering trimmer i could find that used 0.105” line. 0.080” and 0.095” line just don’t cut it in my yard, pun intended. I have a little over a half acre and it gets overran with mustard plant in the spring. I liked the Greenworks however the one i received had a terrible vibration to it and the fact it was $320 was enough for me to turn it. I was going to buy the dewalt 60 volt string trimmer that was attachment capable for the same price as the Greenworks until i saw a review for this 20 volt that confirmed for me that the head would in fact accept 0.105” and this one is half the price and i already have a ton of 20 volt and flex volt dewalt batteries. So this one was delivered today, one day earlier than expected and i opened it up the second i got home from work. Right off the bat i could tell this dewalt string trimmer is build better than the green works. The plastics are off a higher quality and the handle has a nice rubberized grip. My only gripe with this weed eater is the guard is pretty small. It didn’t seem like i was getting hit with too much more than the others but it was more. Now for the fun part. This weed eater is advertised as a 14”. That doesn’t really work for me so i remade the cutter for the string with an additional 1” offset out of some stainless steel sheet metal i had laying around. Now the cutting swath is a little over 16” and with 0.105” line the trimmer has no problem keeping up with my 60 volt craftsman or the 40 volt Greenworks. I’ve also used a friends 80 volt greenworks and i would choose this dewalt over it as well. Half the price and every bit as good performance. I’m stoked to say the least. And with a 9ah/3ah flex volt battery i trimmed my front yard and the battery still shows full bars. None of the other trimmers I’ve mentioned could do that. With or without a little customization this 20 volt Max string trimmer really is a gem. I’m so glad i gave it a shot.

This is very powerful trimmer. When running at full speed the only sound is the singing of the trimmer cord and it doesn't grunt in thick grass and small woodies. It is louder than I expected but nowhere near as loud as a gas powered trimmer. I can still operate it early on a Sunday morning with no worries about waking up the neighborhood. I bought a version that does not come with a battery because I have several DeWalt tools that came with the battery this requires. The interchangeability concept is brilliant - a deal maker when I saw this on Amazon. I already had two of the batteries that came with other DeWalt tools. I've read about the balance of this trimmer on other reviews and I agree that the ergonomics aren't great. This does not need a folding hinge right where the handle should be and the balance is off because the motor is in the trimming head as opposed to on the handle where the battery goes. The motor is heavier than the battery and being at the end of a long shaft it can tire your forearm when holding it up for an extended period of time. For comparison it is heavier than my Stihl FS072 gas trimmer which is also well balanced. The interchangeable batteries, trimming power, and low noise level are selling points. The poor ergonomics and balance are acceptable for the amount of trimming I have to do but could be a deal breaker for someone with more than 30-40 minutes of trimming. If DeWalt could address those cons I would give this 5 stars.

Great battery powered weed trimmer. Bought this unit as I already own the DeWalt Batteries. It arrived well packaged. Very light assembly to use it, just attatch the handle and the guard with a few screws. Only used it once and pretty light stuff but it ran well and seems like it would still cut through heavier weeds as well. Folds up for easier storage but still has a long reach when using it. Built solid. One minor thing it is a little hard to open and close, hoping it gets easier with a little more use.

The DEWALT 20V MAX XR trimmer is a beast. Being cordless makes it super convenient—you’re not tied to an outlet, and it’s easy to maneuver around the yard. It’s powerful, durable, and works great for heavy brush and thick weeds. The double-string design and thick line cut through vegetation quickly, and I like that it folds down for easy storage. The 20V battery is fine for smaller yards, but if you’re tackling a larger piece of land, it will drain faster. A higher-capacity battery makes a big difference for extended projects. This trimmer has serious cutting power, which is great for efficiency, but it does mean you should be mindful around loose stones or gravel since it can fling them. As long as you use it in open areas, it’s safe and reliable. I found this out the hard way when it flung a rock like a bullet into one of my windows from about 30 feet away and broke it. Overall, this is the best cordless trimmer I’ve found for heavy trimming. It combines power, durability, and convenience in a way that makes yard work much easier.

Don't waste your time. Spend the money and get a decent gasoline powered one. I have always had gasoline powered two strokes and my finally crapped out on me after almost a decade. I decided to try this since I already used 20V DeWalt power tools and had several batteries. This thing is for small yard that take 30 minutes or less to trim. With my two stroke, it took me an hour to trim around my fence, trees, other obstacles, and alongside my house. I have to plan it out now that I have this piece of junk. One 6 maH battery gets me 15 minutes...then I have to charge it while using the other battery which gets me another 15 minutes. But then the other battery isn't charged yet so I have to go do something else while I wait. Not only that, but 5 minutes into a battery, the weed eater slows itself down whether it's getting hot or the battery or whatever but then it struggles to cut. Just an all around pain in the ass for anything bigger than a 0.1 acre yard. Also, the angle you have to hold it is very uncomfortable and my wrist is always screaming at me by the time I'm done. There was just not much thought put into this plastic crap...I wish I could send it back and get my money back but it looks like I'll just have to eat the cost. Life is hard enough, save yourself some energy and buy a gasoline powered and capable trimmer. This thing is neither of those. The only good thing about it is you don't have to deal with chokes and a pull cord...that's it.

Holy Crud! I had an earlier Dewalt 20v trimmer that I loved but after 10 years was done. This thing is a animal! So much more power even on low. Very comparable to a larger gas trimmer, but no smell, gas and starts every time!
