works great as well as the more expensive brands

I use it to smooth the legs of my porcelain pots. Looks like new after a week of use. Keep the surface wet while polishing. I attach the racquet with wet leatherette, absorbor works well too.

Pros
  • dimension
Cons
  • small things

600 grit did NOT pass QC

I ordered one and even had to replace it. But the replacement was no better. Most of the wheel is 600 grit, but there are larger diamonds scattered throughout, causing the work to be scratched like a 120 wheel. You can see the picture under the microscope with the two larger (yellow) diamonds and the rest of the suitably sized diamonds can still be seen under the nickel layer. . You can also see the before and after of some synthetic rubies. Before: 400 grit SiC left a smooth surface, but after

Pros
  • Materials
Cons
  • I don't remember but there was something
