Query: Life expectancy: one season

Only buy the B&D LeafHog blower/vac if you don't mind throwing it away after one season. It is so cheaply made it probably won't last much more than that. Mine had the same fate as others have reported: bearing failure, motor growling, ozone smelling ... heat death. My estimate is that is lasted for about 12 to 15 hours of use.
