5.0 out of 5 stars Great lightweight trimmer
Reviewed in the United States on November 1, 2023
This is our second black and decker battery powered trimmer. After about 8 years, the string release mechanism gave out on our first one so we gave it to a handy friend who planned to repair it as the motor still worked perfectly. I love that this is lightweight, yet strong enough to accomplish the needs of out yard: edging, some natural area weed whacking, and cutting back grass in areas that are not accessible by the mower. I wish the battery lasted a little longer, but I believe that there are more expensive models with longer battery life.

Easy to put together, lightweight. My old one stopped working and I liked it, so I know this one will be even better and easy to use. Haven’t used it yet but I assembled it already.

Tool works as it should for what it is, don't expect it to rip through heavy or dense grass or weeds because it's power is limited since it's a battery operated gadget. Someone said it massages the grass well that's kind of true but only because when the battery starts to deplete it spins slower and you have to hold the tool at the right angle to get the expected results. For moderate trimming and edging it works well and as the case with everything it may be a lemon but mine fed out the line and worked just as expected. Just bare in mind that if you want power this isn't the unit you need, instead a gas powered weed Wacker will probably be your best bet. So far so good and believe me I worked the unit hard on a yard that hadn't been trimmed in years and it worked to my satisfaction. Decent battery life on high setting, fed the trimer line out as expected and edged moderately well. (this was my experience)

It is a good weedeater that can fit into the base of the 3-in-1 mowers B&D sells as well making it able to mow small areas too. I use it for trimming, edging, and mowing the sloped areas that I cannot use the gas-powered mowers on. Depending on the size of area to do, you may need more than one battery. The amount I do for just my yard, I typically go through 5 to 6 fully charged batteries. As I have multiple B&D tools that use the 20v batteries, I have plenty to use for lawn care. And the interchangeable battery works with weed trimmers, blowers, hedge trimmers, and even my new vacuum.

I bought this thinking it'd be a great entry-level trimmer. Light weight, no clumsy starter mechanism, no messy refueling, no complicated engine requiring regular maintenance, even converts to an edger; what's not to like, right?

Unfortunately, in order to do anything useful, this has to be turned up to the "high" setting, and on that setting, the battery lasts about 10 minutes. Maybe 15 minutes - point being, the job was not even 1/4 done when it gave out. And the battery/charger is NOT a "fast charge" combo, it takes several hours to get a full charge. I went out the very next day to get a gas-powered trimmer and have never looked back.

I guess this might be OK for the typical suburban 1/4 acre lot that's usually maintained with a push mower and manual weed-pulling. If you're dealing with a much larger space and using a trimmer to handle areas that a riding mower can't navigate around - trees, ditches, trenches, hardscaping, and so on - then just forget about trying to do that with an inexpensive battery-powered device.

There were some other minor things I wasn't crazy about - it's kind of short, even at full extension, which means I kept "trimming" the top of my shoe. Fortunately, this thing's nowhere near powerful enough to cause injury or damage, but it was still a nuisance. The main issue, though, was the battery life. It's pitiful, and unlike a gas trimmer, you can't just fill it back up when empty.

If you're simply looking for an upgrade to hand-pulling, maybe this will be fine for you, but if you're out in the country or have an acre or more... hard pass, just suck it up and get a Stihl or Husqvarna.
