I only used it for one summer before I decided to xeriscape. Includes a basically brand new battery and charger. Sells new for $250.
This lawnmower is awesome. The first time I used it I was skeptical because my grass was veeerrry long. This mower chewed through it like butter. It didn't stall or clog once. I remember being impressed with how long the battery lasted too. I'm not a strong person but this mower is so light, I can push and pull it back and forth and spin it around with one hand like a vacuum. (My other hand always held a beverage.) I've never used a gas lawnmower that didn't require two hands, some muscle, and sweat. It's also so quiet that I could talk to people on the phone while mowing. (Gushing about a lawn mower is so lame but I can't help it.)
Now when I see people using gas mowers, I think how ridiculous it is that those mowers still exist and people actually use them. You'll feel the same, I promise.
Here's the Home Depot page about it:
