This is fantastic. It was a breeze to put together, the battery lasts a good 45 minutes or more, it is easy to handle, and does a terrific job of edging the concrete driveway. the roadside curb, and the borders of my flower beds. It is not too heavy and has loads of power. I am a 5'1" woman 81 years old and this tool is very easy for me to use and carry. The size is not too long even for me to maneuver. It is easy to lean if you get clumps of dirt in the housing for the blade and it is adjustable to suit the depth needed at the time. It seems very well made. The price was reasonable and I think we may be friends for quite a whole.

Great battery powered edger

Style: Lawn Edger w/(1) 4.0 Ah Battery

This edger works great love the guide for along sidewalks and curbside lawns. It is a little underpowered for really thick lawns battery goes down fairly fast on the thicker areas but all in all it’s great

The blade is not sharpen.

Style: Lawn Edger w/(1) 4.0 Ah Battery

I had no problems assembling the equipment. The problem is with the blade. It doesn't have any sharpen. I bough spares blades which have a different configuration and better edge. However I haven't been able to unscrew the bolt in order to install the new blade. It is extremely tied. One would think that you purchase this equipment, at a high price, and would be able to use it right away. In your dream. This is a Third World Country selling things at an incredible high prices, for the profit of the American companies using the manpower of other Third World Countries or China. Since the blade is not sharp, when you try to use the equipment it got disconnected. Therefore it does not work with the blade that comes from the manufacturer. Total disaster.

Worx very well!

Style: Lawn Edger w/(1) 4.0 Ah Battery

Worx very well. ;) More power than I expected from a 20v cordless machine. And with the 4Ahr battery it comes with, I was able to do the drive, walks, and patio without having to change batteries. I own 2 Worx string trimmers, chainsaw, hedge trimmer, drill impact driver, and leaf blower. Love them all.
