Query: Long Lasting

Mulches well, I have cut my 1/4 acre yard with no problems for 7 1/2 years. No gas fumes, no trips to the gas station, no hearing protection required. As stated in other reviewes does not have quite the suction/vacuum power of a gas model but the bagger works well and it bags leaves well.Batteries are finally starting to get a little weak, but over 7 years is not bad, better than any car battery that I have had.
