Bought one of these directly from Grizzly just under 2 years ago. I used it intermittantly to sand the edges off bases of polyurethane plastic model kits. Other than being very noisy when turned on, it seemed to work quite well. Fast-forward to a week ago, went to turn it on & the motor barely turned the belt/disc & then it started to smoke. Called Grizzly customer service & told them the situation. They said it sounds like the motor burned out & they could send me a replacement motor for the unit, at my expense ($81 + shipping - another $20). An entire new combo sander is $125, so I pitched the unit in the garbage & ordered a Wen combo sander through Amazon, couldn't be much worse than the Grizzly I had. Bottom line: my first & last Grizzly purchase. I realize I didn't purchase a top-of-the-line sander, but I did expect it would last a little longer than it did.
