It actually does the job pretty well
Style: Lawn Edger/Tool Only
I floundered around for a few minutes, then figured out how to use it, and then made pretty good progress on my overgrown sidewalks. Yes, it uses up batteries but that's because it actually has enough power to do the job, unlike many "homeowner" tools. The handle is long enough so I'm not painfully bent over while using the tool, and it feels solid and stable. One thing I really appreciated is that it doesn't have a typical pointless, awkward "safety" interlock button that you're supposed to keep mashed down with your thumb the whole time - it's a comfortable one-finger trigger.
Another good 20v tool from Worx. I'm "in".

Works great!
Style: Lawn Edger/Tool Only
Works great and uses the same batteries that we already had from other works equipment. I do wish the pole was longer.

Good value if you have work batteries.
Style: Lawn Edger/Tool Only
Works well for sidewalk edging. Auto shutoff if the blade hits sidewalk or rock.

Disappointed
Style: Lawn Edger/Tool Only
This Worx product does not work as well as I hoped, I have many Worx products, but this one I wish I didn’t order.
