40V HP Brushless Carbon Fiber Attachment Capable String Trimmer with 4.0 Ah Battery & Charger
40V HP Brushless Carbon Fiber Attachment Capable String Trimmer with 4.0 Ah Battery & Charger is rated 4.9 out of 5 by 15.
Rated 5 out of 5 by from Excellent replacement for corded electric unit I previously had a corded electric trimmer with additional Ryobi attachments. The 40V HP Brushless model appeared to have equivalent power and plenty of battery lifetime to use my existing edger and blower attachments. The power available was fine - plenty of power even for the edger and no problem with battery life. The quarter-turn attachment lock works better than the previous multi-turn lock screw. Older attachments have the lock button to the right which is occasionally obscured by the position of the lock screw. Because it's a new product, some of the manual details hadn't been updated: such as that it supports 0.95" line now instead of 0.80.

Rated 4 out of 5 by from Love the portability I have this trimmer for about 4 years now and still love it. No cord to drag around, no gas or oil to worry about. Has plenty of power to cut the tall grass.

Rated 5 out of 5 by from Upgraded Bought this after using a gas powered. This one is lighter and I don’t have to go out and buy gas

Rated 5 out of 5 by from Excellent trimmer! Bought this trimmer months ago. It’s works really great! Will never go back to a gas powered trimmer again. My only complaint is the line feed doesn’t automatically extend when pushed to the ground while using. Have been extending the line manually. I’ve found that I haven’t used very much line so far, and that’s a good thing.

This product is super sturdy and light weight. Love the style and color of this. Good product, super easy to use. Easy to put together. Great product for adults and elderly people:)

Rated 4 out of 5 by from MYSTERY MANUAL Just purchased it. Thank heavens for You-Tube video posts because the manuals were hands down the worst I have encountered. Assembly instructions and cord loading instructions useless. However there are lots and lots and lots of safety warnings.

Rated 5 out of 5 by from Remarkable! This unit was so easy to use, both left and right handed, and did what my gas trimmer did, with half the effort and time! We also own the RYOBI Blower, so we can easily interchange the batteries for longer jobs! I used it to trime all the edging around our house and property which is on an acre of land!
