## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product
*by M***N on January 9, 2025*

Have a lot of stains on my flag stone in the yard that I couldn’t get out with power washing, with this they grind out leaving a smooth surface (120 grid)

### ⭐⭐⭐⭐⭐ Great job
*by Q***N on January 3, 2024*

When I originally used the grinding stone it was burning the edge of the tile but I realized that the grinder I was using was turning too fast. I put the stome on a tool with the proper rpm’s and it did a great job. Just be aware of the rpm rating on the tool you are going to use.

### ⭐⭐⭐⭐ When removing a lot of metal, such as  glaze, rust, slag etc
*by V***E on February 10, 2024*

Trying a lighter ceramic disc, this was good but a bit heavy for prolonged use
