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.

Problematic instructions

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

The product is great once u figure out how to assemble. The instructions don’t do it. I was not happy. Every part was a challenge. The instruction book only shows a photo but not how to get it to look like the photo.
