As some on here know, I decided to go green with my lawn mower after a 3 week epic fight with my gas mower.
It cut about 2/3 of my lawn and than the battery died. I'm on about 3/8 of an acre of land with a pool. One section had not been cut very well because we were having problems with the gas mower so I suspect that it might have something to do with it not making the full yard.
I think the key is to buy an extra battery pack at $99. That way you have a battery in waiting at all times.
The really nice thing about this mower though is the only sound you hear is that of the blade. It runs at a pretty low decibel level. It was nice to be able to cut my lawn at 6am on a Sunday morning and not have to worry about annoying my neighbors. It also was lighter and easier to control than my internal combustion engine mower.
Overall, good purchase. It was on sale at Home Depot. I'll probably get the battery packs next pay period.
