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

Works well
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.

Doesn't Work
Won't stick to tile. Returning.

Assembled backwards. Suction cup and handle are 180* backwards.
Will order again, hoping for correctly assembled product.

Good stuff
Grips well, including mildly textured tiles. For wet drilling the ability to add the water line is handy. Rubber seems as good as some expensive glass lifters I have. So, hoping it lasts for a lot of work.
