Avid Do-it-Yourselfer
5 STAR 40V B&D String Trimmer!
First one in 2012, used it a lot. After bumping the head for string to advance, 4 yrs. later, (Don't do- yes it's in the instructions not to), it started making a noise. VERY Pleased with it I bought another in 2016. Wish battery lasted longer, but runs strong till its out. Lasts about an hour of straight use in tough conditions (longer if not). I have two batteries, always have spare charged, BUY THIS! IT'S THE BEST!

Great tool!
No more gas/oil mixing with the fumes and the mess! In our typical subdivision yard size I can edge all the sidewalks and driveways and trim the rest of the landscape on one charge. I love it!
