I have an 80v Max 21" Kobalt. This will be year three of using it. I bought it because my gas mower had finally died, so I was already in the market. Since I owned an electric car, it seemed only natural to give an electric mower a try. I read a few independent online comparison reviews, and this model was rated highly.
I am very satisfied with it. Mine is self-propelled, but it is so light that I don't actually need to use the propulsion--however, I usually still do just so it keeps me moving at a consistent pace throughout the mow. I don't have a large lot, and can easily mow my entire yard twice without needing a recharge. I don't have a headlight, so I still mow only during daylight hours.
Addiction loves company: I have loaned this mower to a few friends, and now they've all switched to electric, too.
