### ⭐⭐⭐⭐⭐ Works as advertised
*by R***T on March 7, 2026*

I installed a couple of grab bars in my porcelain tile shower. This drill guide was perfect. It held on tightly and guided my diamond top hole saws perfectly. I’m glad I ordered this tool.

### ⭐⭐⭐⭐⭐ Not for small tile.
*by A***R on September 1, 2024*

Obvious, I know but it is larger than I expected. Works great on larger stuff.

### ⭐⭐⭐⭐ Works well
*by B***E on November 7, 2024*

This bracket works well along as you are using it on large enough tiles. If the tiles are smaller than the cup, the grout line will not allow it to keep the bracket secured in place.
