## Customer Reviews

### ⭐⭐⭐⭐⭐ Gotta love a wholly, holy, holey block of steel. LoL
*by R***D on March 13, 2025*

I never thought these would be AS useful as they are. Not just for 1, 2, or 3 inches but it's good with referential measurements as well. Mostly just easy for setting saw depths and stuff. Easier than a ruler or tape measure for short stuff.
