Review: Great rock grinder - I bought this tool and a diamond round over bit to put a finished edge on limestone hearth, mantle and wood box capstones. It worked great and I was very pleased with how it operated. The machine speed was perfect. I used it both in a wet and dry mode with no problems. It was a great value.
Review: Great polisher for the price - I used this to polish a hand poured concrete counter-top for my outside bar/grill. Before the concrete set, I placed colored crushed glass in the surface and troweled everything smooth. After waiting a week for the concrete to cure I started the polishing process by using diamond impregnated grinding turbo cup to knock down any high spots and any flash from the forms. I then switched to the standard gray diamond polishing pads also available through desertcart. This polisher is a beast. The water feature really keeps the dust down but the shield only marginally deflects the spinning water. I recommend wearing a poncho. My only nit would be that the provided hose attachment is about 3ft too short but it could easily be replaced.

### ⭐⭐⭐⭐⭐ Great rock grinder
*by M***Y on October 17, 2024*

### ⭐⭐⭐⭐⭐ Great polisher for the price
*by D***Y on December 19, 2015*

### ⭐ Power button sticks, not OK
*by B***O on January 5, 2025*

The tool works great with one major exception, an exception I find to be unacceptable, after using the tool for only one hour, the power button was sticking significantly, making it hard to turn off. This seems to me to be a major safety issue, I cannot in good conscience recommend a power tool that struggles to turn off.
