Rated 4 out of 5 by from BTW Good but have a spare battery handy My husband bought me this last year. I like it however, where do I purchase additional string??? I see Amazon has comparable string but not sure if it will fit my trimmer. HomeDepot does not have additional string. Can someone help me with the dimensions or where they purchased this hard to find trimmer string replacement???

Rated 1 out of 5 by from Worst Purchase I have made String cutter broke out of the first gate. Everything is plastic and breaks with the slightest impact. Brush head is plastic and also shatters. Buyers beware. No more Ryobi for me. I have some other tools by Ryobi now for sale.

Rated 2 out of 5 by from 1 year anniversary and trimmer is DEAD Purchased this July 1, 2021 Went to use it and won't turn on. Tried the battery in the leaf blower, so it isn't the battery. Sadly, the repair can take 6-8 weeks. Happy it has a warranty, but disappointed I don't have it when I really NEED it.

Rated 5 out of 5 by from Super light weight and easy to use! We bought this today and are so happy we did. It is exactly what I needed--light yet powerful enough to do a beautiful job on our small yard on a single charge. Best of all is that we can use batteries from other great Ryobi tools.

Rated 5 out of 5 by from Great features We bought this at the end of may as we were tired of breaking our backs trying to trim grass in areas the mower cannot reach. I only wish we'd bought one sooner!

Rated 5 out of 5 by from The Green Machine I own two gas weed eaters. But the weight of the machine had become a problem. This simple to use, light weight, battery powered machine is exactly what I wanted. It performs well and I can now get between my plants without damaging any of them. My right shoulder is very happy.

Rated 4 out of 5 by from This trimmer is great!!! For a smaller person it is a great tool, very light. It also has a 3 year warranty which is good. Shows that Ryobi believes in their quality.

Rated 5 out of 5 by from Finally! it works! I've always had an issue with with trimmers' line not working..bumping and all. Big fan of rest of Ryobi products, so I tried it. The battery part is just a bonus with a long charge to do what you have to do, but the string seems to come out magically. You don't have to worry about it, it's there.
