Rated 3 out of 5 by from Takes getting used to I bought this trimmer and it worked great. When it came time to let the tap cord release I had a problem which took a considerable amount of time to resolve. The continuous cording was all tangled up and wouldn't release. It was tough to take apart and put together the first time . By the second time it was easier. Ryobi promised me a free rapid battery charger and we've been waiting many many months for it to arrive.

Rated 5 out of 5 by from Very easy to use!!! This is my second expand-it, I decided to upgrade to a 40v and it came with the timmer attachment. Very easy to use and maneuver. Re-stringing is very simple and no need to take apart.

Rated 5 out of 5 by from extremely versatile I purchased a gasoline trimmer about a year ago with expandable options. it worked fine for awhile then trying to start it was worse than using it. So I purchased a ryobi 40V expand it trimmer and I love it. no more pulling to start, battery last along time for me to complete my yard work, and know smells of gas and oil. also not staining a good shirt while using it. I was concerned about the power that's why I purchased the 40V. Good product, good price love it.
