18V ONE+ HP Brushless String Trimmer/Edger Kit is rated 4.7 out of 5 by 348.
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

Rated 5 out of 5 by from Excellent trimmer This replaced my many-years-old Ryobi string trimmer. This model is lighter weight, more powerful, and more comfortable to hold and use. Easy to rotate for edging - handle well designed to allow for holding trimmer while in edging position.

Rated 1 out of 5 by from It didn't work for me I guess I am the only one who bought a defective tool. I bought my trimmer less than one year ago. It was not even 7 months before the battery became defective and parts came loose on the trimmer/edger. I bought a new battery, but then it comes on and off. I have tried to reach the company without success. It was definitely a waste of money. So disappointed.

Rated 5 out of 5 by from Great for small yards I got this as a house warming/birthday present for my first house and it is absolutely perfect. Lightweight, ergonomic, and battery lasts a long time. Has two settings. I use the faster setting for the tougher weeds and the slower one for general grass and edging so I don't eat away at the alignment too much. My yard isn't very big but I like to keep it clean cut and with all the crabgrass that came with the sod that was planted, this little weedeater is perfect for going out there eventide those weeds poke there ugly little heads.

Rated 5 out of 5 by from Works really good! I absolutely hate weed eating. I mean I still hate it but thus trimmer makes a world of difference. It's perfect for keeping you lawn low and tight!

Rated 4 out of 5 by from Nice tool Has good battery life and works well. I disabled the auto feed as I was afraid it would eat up the trimmer string too fast. Because of this type of auto feed feature the tool lost a star. I would not have bought the trimmer if I had not found a way to disable the auto feed feature.
