My Buying Guides on Mohs Hardness Testing Kit
What I Look for First

Accuracy and Consistency
For me, accuracy matters most. I prefer a kit that gives consistent scratch results and comes with clearly labeled tools or minerals.

I avoid kits that seem vague or poorly documented, since that can make testing unreliable.
Build Quality of the Tools
