Review on AUSTOR Pieces – High-Quality Abrasive Buffing Polishing Products for Effective Finishing by Chris Shepherd

In general, they are good. I really liked the box, but it's difficult to fit everything in it. I'm sure I'll feel better using them. Wheels with higher numbers seem to be too abrasive. Used them to remove rust from motorcycle spokes and scratched some of the spokes. I'm sure I was, but 400 grit is more like 200. If you're careful, they'll be fine. They wear out quickly, but for the price you can buy more. Not as good as the Dremel EZ lock as you have to remove the wheel when it wears out, but still a lot cheaper. Honestly, if you want quality spend your money on a Dremel, if it's not that important to the job at hand they will. One more thing, I wrote the color and grain on the box with a marker so I can remember, but being color blind it's still a bit difficult to get the right one (other than black). I also took one of each color, put masking tape on the shaft, and wrote the color and grain on it to use as a guide.
