Awesome Cordless trimmer!
I sold my Craftsman 4 stroke trimmer because this cordless has the same power but way less weight. Now I use it 10 times more than the gas ones because I don't have to check the fuel, (mix gas and oil if low), prime it, choke it, start it, let it warm up then use it. With the cordless DeWalt you just pull the trigger! So it gets used way more often. Im very happy with the unit, the other thing is the gas trimmer would make my hand go numb because of the vibration of the gas engine and it could also burn your leg if you weren't careful. My wife uses this too and I don't have to worry about someone using the wrong gas or not getting it started! Use safety glasses because this thing is a beast and on the high setting it really goes. The battery lasts longer than I do and charges fast. The best idea on batteries is also the built in power gauge.

"Tired of mixing fuel"
I fully charged it , trimmed all around house, 2 sheds, went up my road, went around trees in the yard and still showed 2 bars of charge. I'd still probably be pulling the cord to start my other one. Slip the battery in and you are off and running. Best investment! After I got trimmer went and ordered the blower too. No more pull cords !!!

Awesome!
I'm a homeowner and have been waiting on DeWalt to come out with this piece of equipment. With the rebate offer of a free extra battery, I went to Lowe's and picked it up and am extremely satisfied!

Never have had a bad Dewalt. This is a replacement for a Core trimmer 2 years old, my nabor & I each had a Core and both failed after 2 years. Core said they would fix his for $150, Ye both boujght new trimmers. I had the blower h hedge trimmer and love them both. The line trimmer came with a u amp hour battery, so I mow have 3 batterys.

Great Quality Trimmer
I wanted to replace a Black and Decker that had battery issues. I am a fan of Dewalt and this trimmer works great. I highly recommend for large jobs. I would their smaller trimmer for lighter duty however.

This is the best product Dewalt has made yet. As an operation manager for a large landscape company, my crews love this new equipment. By keeping my crews away from the gas station to fill up there equipment has saved my company a lot of money.

Great trimmer
This trimmer is very easy to use and the battery life is much more than I expected. It is a little heavier than I thought it would be but I will still recommend one to anyone

Is it any good at edging lawns?
Babs on Jun 23, 2016
BEST ANSWER: Absolutely! This trimmer is fabulous! I edge all my lawn along the my paver front walk, the concrete driveway, the road edge and all my planting beds.
This unit has all the power of a gas model but none of the hassle. Battery lasts a long time and recharges relatively quickly. I also have the hand held blower which is another great DeWalt product.
Can the battery in this trimmer be used in any of the De Walt chain saws or leaf blowers?

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
