Review after 2 months of full time, professional use.Since this belt sander is such a great value, price and quality considered, I’ll give it 5 stars. Tracking and power were perfect, right out of the box. Welds, balance, speed variation, and attachments are all very nice. I fabricated a tripod stand for it that is heavy and allows me to stand anywhere around the grinding surface.When using the big wheel, or the graphite platen (especially at full speed) it does not bog down under intense pressures.Having said, here are some things you may want to know:-It takes about 10 seconds to ramp up to full speed. If I need to hurry up and clean the burr off a cut, this is not the grinder I use.-the “run” and “stop” buttons are so small, that I often miss them. I spent too much time figuring out a way to make the buttons bigger and easier to push on the first try. —even used actual “buttons”. See photo--82 inch belts are not popularized in the US, I could not find anyone who sells a production version ceramic belt in that size (but you can easily buy aluminum z belts)-Combat abrasives custom made 36 grit, 82/2 ceramic belts, for about 10 dollars each. That’s a great deal, but you have to buy a dozen of them to get the custom size. To me, it was totally worth it.-the speed control system is not specific to this item. It seems to be a generic control panel that has many potential uses. It will come all set up, but it looks a bit hokey and I hope it lasts.-mine came with the power transformer. The motor is a 220v and it needs to be transformed into the 110v. I hope that lasts too.Over all, I’m thrilled to add this belt grinder to my shop. It is far more versatile than my 3/60” upright, and, as a career metal sculptor, I love having this hungry, powerful, but precise machine! I still get a kick out of showing people the slow-2800 rpm variability.Jacob Dean
