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.

Don't waste your time
The batteries DO NOT stay charged long enough to mow 20x50 yard!!!! On a full charge on all 4!!! Not worth the price or look!

The best mower ever,
I had 2 back surgeries and was having a hard time starting my gas lawnmower with pulling up and at an angle to start, also they are so heavy, this mower IS a DREAM come true, it's lightweight, easy push start, mows great , easy to clean and maneuver, my yard looks great and it's so easy to push and start, worth it's weight in gold

Looks great but wouldn’t start
This product looked great after removing from the package and assembling. Battery charging went great with the included batteries and charger. However the mower would not start so it was returned. The return process was quick and straightforward after the pain of repacking the mower.
