Excellent product! I couldn’t be any more satisfied.

Why did you pick this product vs others?:After buying several off-brand edger/weedeater that never worked worth a darn, I decided to buy a brand name product. This did not disappoint! It’s lightweight, easy to maneuver, and I was able to complete my entire yard without having to fix the line one single time. I was almost giddy, I was so happy with this product!!

Don't buy used/return

Rarely have a problem with returns from Amazon but the 2 batteries that came with this trimmer won't charge with the included charger or any of the 3 I had from the other 20v black and Decker tools, otherwise the trimmer works better than my older B&D battery trimmer.

Get Those Weeds Under Control

Quick delivery and easy assembly. Has adequate power for the average person and reasonable price. Lasts maybe 5 years before it wears out. Lightweight and gives those weeds a good beating.

This is a surprising value!

This is just right for someone small , as it is very light, while being full size. The battery lasts just more than 30 minutes.I have one acre and I can get at least half of it done on one charge. I am so happy with this product, It’s fast, is easy to use, it’s light, it’s very reasonably priced, and it gets the job done!

Great machine awful battery

Only been using black and decker brands. They have great equipment; wish I could say the same about their batteries. Only used the machine once and did a fabulous job. As for the battery, worked for 5 minutes with a full charge. Luckily for me I have other black and decker batteries that works well. I have purchased or received 8 batteries and only 5 been great. Two batteries would only last around 5, maybe 6 minutes. One battery would not work at all, complete junk. Enjoy black and decker equipment, flip a coin on the batteries.

Still strong after 6 years.

Brought 6 years ago. Still going strong. I use it twice a week for about an hour each time spring thru fall. Mostly on yard edging.Even with a broken wrist it is light enough to use a strap around my neck and kept going. I bought a larger battery other then that, just awesome for the price.
