18V ONE+ HP Brushless String Trimmer/Edger with 4Ah Battery and Charger
18V ONE+ HP Brushless String Trimmer/Edger with 4Ah Battery and Charger is rated 4.7 out of 5 by 61.
Rated 5 out of 5 by from Nice & Light! Just picked it up from Home Depot, went together easily, and I love the light weight. Popped the 1.5ah battery out of my Ryobi One Brushless drill to test it out while the 4ah battery that came with it charged and quickly trimmed around the house. Will give the larger battery it's test tomorrow when I take it to my store for the 1st cut/trim of the spring.

Rated 5 out of 5 by from Powerful It is light but powerful. My 10yr old son was able to trim the edges around the walls and sidewalk with the trimmer. He did not complain about it being heavy at all. This is compared to my 2 cycle craftsman trimmer that he would complain about using. Also it does not jerk at the pull of the trigger witch to me is great! I was able to use the same battery on the blower too after the trimming was done. I could probably do the edging with the same battery, once I buy the edger attachment. This is just our first time trying it.

Rated 5 out of 5 by from the edging made it worth it alone Being able to swap over and edge is awesome. Ive used gas trimmers all my life and always just turned it sideways after to trim up the driveway/sidewalk. But i always ended up having it catch and pull into the grass, leaving a burnt spot instead of a straight line. Made it a delicate balace and i took 3x as long to do it. This thing didnt even try to pull, and it didnt feel like it was because it was underpowered because it cut just fine. The wheel makes it easy to keep the lines straight too. Definitely worth it imo

Rated 5 out of 5 by from Light weight with excellent features I bought this yesterday at Home Depot mainly because it was light weight. I am 70 years old so I didn't need a heavy trimmer. Anyway I unpacked it and had it assembled in 5 minutes and put the battery in the charger which were included. Features are great. The foot operated control which changes it from a trimmer to an edger is shear genius and the automatic line feed is another great feature. This morning I plugged in the battery and went to work. Performed as advertised. You won't find a better deal anywhere!

Rated 5 out of 5 by from Great quality at good price I bought this as a gift for my retired mother because I also own this same product. She loves the colors and ease of use. These things are great! The trimmer took only a moment to assemble (Four small screws to attach the guard). Once the battery was charged up. it ran like a top, doing everything I asked of it. The blower amazed the bejesus out of me, Deceptively light, it is amazingly powerful and whisper quiet. No smelly gasoline or irritating cords. The future has arrived!

Rated 4 out of 5 by from Awesome for electric trimmer This was my very first time using an electric trimmer. I’ve used various gas powered ones in the past. It’d be a disservice to compare between the two. But my use with this particular RYOBI 18v brushless trimmer has been satisfactory and it handled yard trimming with ease. The one drawback I had was that the battery life caught me off guard. I read on the box that it had an hour of battery life per charge. This is a bit misleading as it is completely determined by the amount of power you put into the trigger. If your going full blast, maybe 20 min of use at best. You would really have to be light on the trigger to get a full hour. Other then that, this is a great trimmer for its price point. I’d def recommend it. I may need another battery so I can swap out to get through my yard in one pass. Yard size 15,000 sq ft, I weed whack at least 5-8k of sq ft due to uneven rocky surfaces.

Rated 5 out of 5 by from Best Choice. Exceeded my expectations! The fact I didn't have to chase down a charger and separate battery was a huge time saver. When I got home it was fully charged and ready fast. Did my entire yard with fence (both sides) and plenty of items to edge around, the LOW setting tore up the grass and was able to put it away with one less than full on the battery meter. 5 Stars!!
