Wide surface
Style: Lawn Edger/Tool Only
The edger has a very strong motor cuts great! As long as you are placing the edger on a wide flat surface. If the area you want to edge is along the curb and narrow the edger is to big and bluky for a narrow edge strip

Very good lawn edger
It does a great job and easy to create straight, clean lines. Does not do well going around curves.

Great value.
Works great, easy to handle, relatively quiet, and powerful enough to cut through 3 inches of sod.

Trim me up
The trimmer works as described. It arrived as promised, it manicured my 80 ft linear ft in no time. I ran 2 passes because I hadn’t done it in decades.
