18V ONE+ Brushless Attachment Capable String Trimmer Kit is rated 4.6 out of 5 by 206.
Rated 4 out of 5 by from Powerful tool The tool is powerful and can cut grass nicely, but the guard that it comes with is not useful as it doesn't protect you from debris.

Rated 5 out of 5 by from Battery powered Weed Eater I received this Ryobi weed eater for Christmas. It is going to replace the Ryobi weed eater I got for Christmas about 8 years ago. I am still using my old one, but it is getting real load, and sounds like it is going to die anytime now. If the new one holds up like my old one, I certainly can't complain. I trimmed weeds around our ditch and lake, getting it wet many times, and it is still keeps on ticking. I am sure I waill get the same service out of the new one.

Rated 5 out of 5 by from Best trimmer Great trimmer. Love the power. Wish it was available in my store in Hawaii. Couldn’t order it either. Had to have my daughter pick one up in CA and mail to me. Home Depot you need to do better.

Rated 5 out of 5 by from Seems like a good grass trimmer I've had this for just over a week and it seems to do a really nice job on grass and lite weeds. It could use a heavier line for use on bigger weeds, although I purchased the brush/weed cutter attachment to handle the heavier stuff.
