I’ve had no issues at all with this lawn edger. For the price point and the amount of edging I need to do, it works great. It has plenty of power and gets the job done cleanly. Just make sure you have a long enough extension cord for your yard or projects. Overall, no complaints—solid product and an easy 5 stars from me.

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".
