The same symptoms as the previous reviewer, very weak motor, noisy and makeshift solutions with cable ties to get the belt sander to work... the icing on the cake was the switch that gave up the ghost...

Very noisy tool, it took a lot of work to assemble because the screws inside the tape dispenser were loose and it didn't work properly. In the end, when it did work, it struggled easily for its wattage, like a compressor. Finally, the switch broke and you had to continuously press it for the machine to work. I have sent it for repair under warranty since the switch is with a relay and cannot be easily fixed at home. I don't think a twin wheel is worth getting with a tape dispenser after all. It's better to have two separate tools. It's a shame for the money I spent.

I bought it three weeks ago and I use it for hobby purposes. It makes minimal noise, it has no vibrations at all, and I can spin the tools without screwing it in. I made the mistake of placing a brush instead of the coarse stone, but I removed it because even when screwed onto the bench, it had so many vibrations that objects were falling off the shelves, it made a lot of noise, and when I pressed the tool on the brush to clean it better, it would stop spinning.
