I knew it was 145 pounds, but when it arrives, you realize how big and heavy it really is. My 2-car garage only has 2 circuits, a 220 and a single 110. With lights on and the dust collector running, the sander would pop the 110 circuit breaker every time. Rewiring the sander for 220 is fairly easy, and solved that problem. I've had the chance to use it few times and it works great! Without the dust collector running, it'll fill the garage with dust in no time. It'll remove a lot of material (hardwood), fairly quickly, and the motor doesn't bog down at all. It does make some noise tooI I spent some time adjusting the tables so they were square to the sanding surface. Also, I did have problems with the belt not tracking properly, and the quick release is very touchy. A small nudge in either direction will cause the belt to track to one side or the other. I noticed the belt that came with it was stretched a little in the center, and I'm hoping thats the problem. I bought some new ones (a couple different brands), haven't had a chance to try them, but hopefully that solves the tracking problem. To be fair, I'd say this thing is overkill for the occasional hobbyist, which I sort of am, but I do like it. This is my second Grizzly tool, and I'm impressed by the overall quality. If your looking for a HD sander, I'd recommend it.
