Perfect for my needs

Mark July 20, 2026

I really like this trimmer. It is the first battery powered trimmer I have ever owned, and it has not disappointed. It is light weight but has plenty of power to get everything I need done. I had issues with getting the line fed correctly on previous trimmers but this self-feeding works great. The only thing I don't care for as much is the safety button that needs to be pressed in to press the trigger. It's a little awkward to use but the safety is important. Overall I highly recommend.

20V is a marketing lie, it is the same 18V batteries of yonder save with a new connector so you can't use your old 10V batteries, in the EU they forced B%26D to market this as 18V but the connector is different anyway.

trims well, battery life not great.

arstymumsy July 29, 2014

It trims well but the battery life isn't very good. A second backup battery costs more than half the price of the entire trimmer itself. Not impressed. But wanted a trimmer that wasn't gas powered and trimmers with cords are cumbersome. I wish they'd improve battery life or price backup batteries more reasonably.

Pleased with this purchase

KYcanoe September 22, 2016

I love this weed eater. I have never been able to effectively handle a gas powered weed eater because of the weight. This weed eater is light but does an excellent job trimming. I trimmed at our lake cabin and then at our main house and the battery is still strong. I am 70 years old but very active and do not mind yard work. This tool is great!

A great little weed-eater!

Shinyhalo June 17, 2016

Actually, I returned this because I had bought one of these last year and couldn't seem to get it working this year, so I ordered another one. After I placed my order, I got my old one to working (I hadn't put the battery in properly). So that is the reason I returned it. I love it! I am a 67 year female who cuts the weeds around my house by myself and this little weed eater is just about the right size and weight for me. I usually get about 15 minutes of use out of it before I have to recharge the battery, but hey, that is about all I can do before I have to rest. So, yeah, I really like it and would highly recommend it.

Great Buy on Weedeater

dja1905 March 17, 2017

Being an elderly woman, this weedeater worked wonderfully for me! It's very lightweight and helps me keep the outer part of my property well-trimmed. It's quiet operation is nice. It works very well in chopping down tall grass around trees. Although I wouldn't recommend it for heavy weeded areas, it works fine for what I ordered it for. It came in original box with a battery, string, and battery charger. A great deal altogether from Black and Decker.

Very nice for a small yard.

DedasKitchen April 12, 2014

Works great for light trimming. I was sick and tired of running through gas powered motors every couple of years so I decided to try this one because the battery is interchangeable with a Black & Decker drill I already had. Pros light weight, about 45 minutes run time on one battery, super quiet Cons takes about 5 hours to recharge, only has a one string feed so it won't cut through very tough grass quickly In my case, I keep all fence lines, bushes, tress, etc., sprayed out so I only need light trimming. This is perfect for me. But if you have tall, thick grass or a lot of trimming, go with the power of a gas trimmer.

Weed wackier works well

Randall March 24, 2026

I bought Black and Decker because I use the 20v battery for several shop and yard tools. The trimmer is easy to use with some minor annoying flaws such as the lower handle not locking in well. Walmart had a better price than Home Depot , Ace, and Lowe's.

Good value for the money

BrodheadWI June 5, 2016

I actually paid less than $70 for this item on sale. It's fully charged in less than an hour and the battery easily last long enough to trim around my entire 1/2 acre lot. It's much lighter than my old electric trimmer and getting the trimming done takes a lot less time now that I don't have to drag the electric cord around behind me. The only downside is when trimming thick, tall grass, the grass tends to wrap around the head of the trimmer rather than getting cut by it. But, for regular grass and weeds, it's got plenty of power to get the job done.

Very light weight and easy to use.

AMM121212 October 30, 2014

Assembly was real easy and consisted of pushing the plastic guard into a slot (1 screw) and attaching the D shaped handle (1 bolt). Just the ticket for what I needed. Very happy with it. Light enough in weight to be comfortable. This trimmer does what it's supposed to do, decent price too. Great product. I love doing the edging with it, you can never do it wrong.
