Review: Works well - Wasn't sure how this lawnmower was going to be. It's battery powered . Received it late so it took me awhile before I could use it. The lawn had already been cut . Fast forward to its use. This thing is a beast . I was using a corded lawn mower. It was good, but wanted something that I didn't have to worry about keeping the cord out of the way . Well .... I'm glad a bought this lawnmower. It's a great tool. I get the lawn cut so much faster now. It uses 2 included batteries. They are powerful and get my small lawn cut with plenty of energy left and in record time . I totally recommend this lawnmower. I've now used it twice . NOTE : It's weird trying to get the push bar unfolded and connected The pieces don't always line up as they should. Also, it has a weird start up to power the mower . You must hold the lever back, then push the button on the side to start . Also, it has a grass catcher. The lower rear flap on the mower can impede the grass catcher from collecting the cut grass. That flap is not removable. Place the grass catcher over the prongs that look like something is supposed to slide into them and on top of that lower flap . Enjoy.
Review: See above - Lightweight and easy to control. Cuts very. well
