Denny,
I'm on my second HF tumbler. The first walked across the floor, snagged the cord on a sharp edge, chafed through the cord and shorted. After I fixed that, it worked for a few weeks and the motor smoked. The replacement has been good, but if I need to use it unattended I put it in the driveway surrounded by a few bricks.
