I have this one I bought a couple of years ago, so it might be slightly different:
http://www.homedepot.com/p/EGO-20-in-56-Volt-Lithium-ion-Cordless-Lawn-Mower-LM2001/204746234
I don’t have a lot of grass, and it easily handles the whole thing on a single charge.
Likes:
Fairly quiet (compared to a gas mower)
Charges quickly
Folds up, so takes up less garage space
Light, easy to push
Super easy to start
Dislikes:
The front of the mower sticks out too far so it’s impossible to get into tight corners
Bogs down/stalls in tall grass
