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 66.
Rated 5 out of 5 by from Easy to Use Bought this unit to replace a gas powered model. The battery lasted about 1 hour of run time, cutting through heavy grass. The Auto Line feed worked better than expected with all the wet grass on the unit. After years of bumping the trimmer to feed line, just letting go of the throttle and having the line feed was appreciated. The High and Low speed settings with the variable speed trigger is a big improvement over the gas powered unit. This unit on Low speed and light throttle will cut nicely thru mid height grass. The adjustable string length 11" or 13" helps saves battery run time.

Rated 5 out of 5 by from This thing is a beast! I have owned this for well over a year and it is powerful! I can run the trimmer around my yard in about 30 minutes and usually just barely start using a second battery. It cuts down everything smaller than a sapling around a fourth to a third of an inch in diameter. Weeds don't stand a chance. I'm planning to upgrade to the 40v system...I can't wait!

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 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 Excellent for basic yard work String mower and edge trimmer is good for basic lawn work. The edger is plastic so you need to edging a little bit more often as it won't cut the thick roots.

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!
