Great Trimmer
After going through several gas trimmers due to the ethanol in fuel I decided to try a battery powered trimmer. I purchased this several years ago. I love it. I own an acre and it takes two charges to do my whole yard but it does the job and has been for a while. It has plenty of power for regular weeds and grass. It really is a great product. If it broke tomorrow I would buy another in the blink of an eye.

Very hapy with this product. went with the B & D cordless mower last year with the same 40v battery and have been extremely happy, so it was a no-brainer to go with the matching trimmer. had an early Craftsman incarnation of the cordless and a couldn't make it through the entire yard where this one makes it on 1/3 of the battery - nice! plus, unlike the gas powered one I had after (loud, hard to start, and one side of my body shook for hours after using it), the B & D is so light and easy to use.

EXCELLENT choice to replace my gas/oil trimmer. Relative showed me his. Lightweight, compact, and quiet!!! Have a bad back. This is so light, it’s just great. Replacement spools are very affordable and easy to replace. Should have done this long ago.

Less quality
It’s lighter weight makes seems less well made than previous model. Also battery life is shorter than 2.0 & 2.4. The method to go from edger to trimmer isn’t nearly as good as other models.
