    • Excellent Quality
This is the second time I have purchased this exact trimmer. The first time I bought it was around 2011 and it lasted until 2025. The trouble is the battery wouldn't take a charge anymore. I shopped around but I couldn't find one that was better priced for the function and so here I am. Very pleased. ... show more

    • 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!! ... show more

    • 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.

    • 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. ... show more

    • 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! ... show more
