Best trimmer ever
Bought it 1 1/2 years ago. This trimmer works great. The best trimmer that I have owned, 5 different models of previous trimmers all had different issues.
This one combines all the good things.
First time I used it on 70 feet of over grown bushes, a lot of the branches where 3/4 inch .
This trimmer cut through them with ease, was easy to handle and produce straight even cuts with very little battery drain, still had 3 bars on battery when done.

Truly amazing
I bought this trimmer as a bare tool because I already had some 20V tools (which I love. I needed it to help tame the blackberries at my new house. I have been blown away by how effective this is at cutting both green and dead vines all the way up to the advertised 3/4” capacity. I usually top off my batteries when I’m done, so I haven’t run them down yet, but I’ve run the trimmer for over an hour, and the fuel gauge has never been lower than 2 lights. I think my hands would fall off before I could drain one of my 5Ah batteries. It’s also very well balanced.

Quite working on first use!
Having bought many Dewalts battery operated tools for both home and my business, I have been mostly satisfied with the performance of the tools. Except the longevity of the tools and the lousy high priced battery life. This trimmer didn't even last thru the first battery charge. Quit working all at once as if it had a dead battery check the battery wasn't dead tried after recharging the battery to no avail. Completely dead. Sorry I couldn't give it less than one star.

Much Better than I thought it would be
I got tired of cutting the extension cords of the corded hedge trimmers. I read numerous reviews and ratings of the Dewalt 20V MAX 22" Hedge Trimmer on a few websites, so I thought I would give it a try.
Very impressed with the performance, the light weight and run time with a 5 amp battery. Blades are very sharp and cuts through over 3/4" shrub branches. Makes trimming a lot easier.
I highly recommend the trimmer, Dewalt has a 90 day return guarantee if you do not like the product.
I also recommend creating an online account and registering all of your Dewalt products.

Loves this tool! Easy to use and does a great job. No fear of slicing through an extension cord. Really love the whole FLEXVOLT system of battery operated Dewalt tools.

Great Tool!
I'm very happy with this purchase, I've used it where I never had used a hedge trimmer before due to extension cord restraints, so no cut up arms due to pricker snags while mowing, it cuts through 1/2 inch diameter branches like butter and I'm using the same batteries that came with the Dewalt brushless drill that I purchased. I should have went cordless much sooner.

Hedge Trimmer 20v Sturdy
So far, like the 20v hedge trimmer. Have had other brands, but the DeWalt blade is much more well built. Time will tell.

Have about 100’ of small leaf hedges that I cut about once a month. Been using it for about 2 years now and no problems at all. Easy to maneuver and light enough to do the 100’ farely easy. Cuts branches up to 1/4” pretty easily. Already had a couple neighbors ask where I got it from.

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 120 days.
