## Customer Reviews

### ⭐⭐⭐⭐⭐ Non magnetic
*by D***R on June 9, 2025*

Needed a set fer years

### ⭐⭐⭐⭐⭐ These are great addition to my tool box
*by R***. on January 8, 2025*

These are really great, but I need one as small as 0.015. The smallest one in this kit is 0.050.

### ⭐⭐⭐⭐⭐ Very, very accurate!
*by V***M on February 24, 2020*

Initially I ordered a stainless steel Feeler gauge that was inexpensive only to find that the feeler measurements were all over the place. Not one of them was accurate, and not even close. So I returned it and found this gauge set and ordered it. Since the one I returned was very inaccurate, I tested the Runningfish feeler gauge for its accuracy. Wow! I was very surprised. Almost every single measurement was within 1/1000 mm. The only one that was out more was the .60mm gauge which measured 0.62mm (close enough for my work). This gauge is worth more than the price. I love the brass instead of the stainless steel gauges. Yes, I scratched the 1 mm gauge to make sure it was all brass, and not just brass plated. It is all brass. Be very careful with the .05mm gauge, it is paper thin and can be easily damaged.
