Well designed

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.

Black and Decker 40 Volt Trimmer

This trimmer replaced a 20 volt that lasted for more than 10 years. The 40 volt definitely produces more torque and cuts the time to trim our yard almost in half. I love it and am considering getting another for backup🙂.
