I haven't even owned it a 13 months and already it blew the oil out of the motor. I have probably used it about 10 times to pump water out of a dry well and a low point in our sidewalk. It worked most of time, not great but not bad either. I probably let it run dry a few minutes before I came out and unplugged it and there was oil all over the place. I am very disappointed with it.
