Rated 5 out of 5 by from Trimmer I bought this one to be used at the cabin as I already have one at home. It works just as well as the 1st one I purchased.

Rated 5 out of 5 by from Perfect. I just got this yesterday. I was really just looking to pick up a new battery. While I was shopping online, I saw this combo for $30 more than the battery alone. So happy I got this. Works great.

Rated 5 out of 5 by from String Trimmer Great trimmer. Very powerful. Batter life is great. I have used the 40 v lawn mower for just over 3 years it is so quiet and works great. 4o v blower is also excellent.

Rated 5 out of 5 by from So far, so Good Cuts well, even through crab grass/sturdy weeds. Battery lasted through the entire front and back yard, trimming lots of things that hadn't been trimmed in a while. I'm keeping my brush cutter, but the other gas trimmers are finally going away.

Rated 4 out of 5 by from Gas-Like power I bought the String Trimmer 2 weeks ago and i loved the handling, there was less vibrations, the speed trigger was very precise, and the Bump feed head is very useful; but i'm not sure why it's made from plastics though. There was never one time that the battery had died. The trimmer can spin really fast at 10,000 RPM. I find it very easy to trim in tight places. It makes clean cuts around structures.

Rated 5 out of 5 by from Excellent choice.. just buy it! Extremely satisfied with this purchase. My gas trimmer absolutely wrecked my back and wore me out after doing an acre. This thing is a dream being so much lighter and no battery issues.. it does all my lawn plus edging on one charge. Couldn't be happier!
