Have only used this mower three times, but each time it has done the job. I have a small to medium sized lawn, and was able to cut it twice without having to charge the battery. Mulches extremely well. You do have to be aware of the fact that you can't let the battery recharge for more than 18 hours, I think it is. Anything more damages the battery, apparently. Battery is easily accessible, and easy to remove, should you want to. Can charge it while it's in the mower, or you can remove it and charge it with included attachment. So far so good.
