18V ONE+ HP Brushless String Trimmer/Edger with 4Ah Battery and Charger
18V ONE+ HP Brushless String Trimmer/Edger Kit is rated 4.7 out of 5 by 355.
Rated 5 out of 5 by from lightweight but powerful Only used it once so far. Seems to have much more power than the previous Ryobi 18v. Hope this one lasts as long as my first one. The battery finally gave out after 6-7 years.

Rated 5 out of 5 by from Great trimmer This is a great trimmer that will make your trimming the grass so easy you will love it. The trimmer is supper light, and you will have no strain on your back. It is also super easy to put together and operate. The auto feed line is the coolest feature, love it. Iam totally satisfied.

Rated 5 out of 5 by from Great Tool! Purchased the trimmer 10 days ago, easy to assemble, 1 hour for full initial charge. Easy to use, lightweight, plenty of power on the "low" setting to do my normal trimming and edging, able to do my complete yard in 50 minutes on a single charge
