## Customer Reviews

### ⭐⭐⭐⭐⭐ Good
*by R***E on September 1, 2024*

Work well

### ⭐⭐⭐ Decent but scratches off easy
*by S***M on February 16, 2025*

This will get the job done if you're looking to measure cracks. I'm not positive how accurate it is but if you're the only one measuring cracks you can easily compare to old photos or notes using the same card to keep at least a consistent idea of how the cracks are forming.If you move the card around on the surface of a wall you can sometimes scratch the printed measurements off of it.This is good if you need something quick but I wouldn't purchase this for a work site. Get a pair of calipers or something.

### ⭐⭐⭐⭐⭐ Needed to measure foundation cracks
*by J***K on March 18, 2024*

Does a great job of measuring cracks in foundation blocks. Needed it to inform home builder which cracks need to be repaired before the initial warranty runs out.
