Review on Electric Grinder Sanding Adapter by VISLONE by Narendra Thapa

The mandrel adapter was not standard as another noted, it had to be rethreaded to 5/8 11 threads. I'm sure there are a lot of people who can. (No, not really) The clamp that holds the belt sander to the sander's neck is smooth on the inside so it won't stay in place when pressed against the sander's neck. I have two coffee grinders, none worked. And when I managed to hold the device by the collar of the grinder, the belt kept slipping off the pulley at the end. That's a really weird decision, the pieces aren't thin, they're strong. It's just that the design details are poorly executed. As a result, I found it almost impossible to get it to work on my coffee grinders. Harbor Freight had a complete unit that cost just a little more than the weight of my Vislone sandpaper. Anyone else use paper?
