What Customers Are Saying

The cordless string trimmer and edger is generally well-received by customers. It is praised for its power, battery life, and ease of use compared to gas-powered or corded models. The variable speed control and automatic line feed are noted as helpful features. Users appreciate the lightweight and cordless design, finding it comfortable and convenient to use. However, some customers have experienced issues with the trimmer head dispensing too much line or the motor seizing up after limited use. Battery life may also be a concern for larger properties. Overall, the product appears to deliver good performance for most homeowners, though a small number have reported reliability problems.

Strong motor, cheap plastic string delivery design

Powerful motor but the string trimmer spool housing only lasted less than a year. To make it worse a universal (read better designed) trimmer spool housing in not available for this model. It blooks like the only way I can use this trimmer is to buy a B&D string spool housing and wait for it to wear out, again. I'm not just talking about the spools which get eaten up underneath, but the all three parts, the outer housing, the orange cap and the spools don't last under normal use.

Hard working tool for the DYI Lady Home Gardner

Would Recommend

I've used this trimmer for a number of years. Great for both edging and trimming those tight areas around light posts that the mower can't reach as well as edging my 100ft driveway. It's easy to switch between trim, easy to change the string spool, and easy to be cleaned up. I am a female, 70+ years old who does her own1/2 acre yard. I have used other peoples trimmer brands and they were just too heavy! I use a rapid charger so I can take a break between front & back yards (Don't want heat s...

Trimmer head fell partway out of housing, ruined

I bought this string trimmer in April 2024. 2 days ago (August 2, 2025), the trimmer head fell part way out of its housing, as if a bearing or retainer had given way. It is now inoperable. I do not recommend this product.

Works well but I wish was more durable.

I enjoy landscaping areas of my 200 acre property but I am 65 and have musculoskeletal problems so a lighter cordless electric is mandatory for me. Given that, this appears to be the best on the market. I have three batteries which I charge each day and that gives me 45-60 minutes of work time which is about what I can do anyway. No problems with the string advancement. The major issue is just that it isn't heavy duty enough for my work. Current unit just died and I'm ordering my fourth. I...

Works Great!

Would Recommend

I had the older version of this trimmer for years. After it gave out, I decided to get a gas one, which worked well, but I also missed the cordless one so I ordered this newer one. I read mixed reviews with some saying the newer model wasn’t as good. I took a chance because I liked my other one and wanted to be able to use the batteries I had for it. I’m not sure what the complaints were about because this one works just as well as the older version. The auto-feed works great, and the line cuts ...

Excited about doing yard work ~ this is the Item!

Would Recommend

This is my second purchase of a Black and Decker trimmer. I had one for over 10 years and I just had to replace it with this model. I first tried a cheaper brand and quit it after 2 times . I visited my trusted brand Black and Deckers website and purchased this model. I have used it 4 times already and it is effortless. I love all the functions this trimmer has. Never go wrong buying a Black and Decker product.

Backsaver Plus!

Would Recommend

This weedwacker is a backsaver, with plenty of power and yet not so explosive in power that you fear what it could do to the surrounding plants and creatures that live in the yard, it doesn't get away from you. I have loved and used this for years and it's still going strong, highly recommend it!

Should have stuck with B&D

Would Recommend

Have an old coded model forever. Just wanted to ditch the cord. I love the easy reload spools. Have a Kobalt with double line, hard to load so I bought this one

Weak wiring

Would Not Recommend

I've always liked B&D products so this seemed like a no brainer. Purchased it back in summer of 2020 and generally used it every couple of weeks that year and 2021. It worked fine until this spring when sometimes it would start and then immediately stop. Sometimes if I would shake it or smack the side, it would start for a while then just randomly stop. I finally figured out it was something to do in the switch area. I actually opened it up and found that one of the wires in the handle was disco...

Adjustable for a short person

Would Recommend

Like the fact that I can adjust the length. One of the few that has that option of the Cordless with a 40-volt battery that are reasonable priced. I am short so that is very important to me.
