Review on 🐉 Reddragon Digital Resolution Coating Thickness by Richard Alemayehu

This was a good value product and I wanted to like this product. It's very easy to use and understand, but I couldn't calibrate the sensor. The evidence is very contradictory. I may have received a poor quality product, but I wasn't impressed. **Update** The seller contacted and resolved the issue. I hope the unit I received was just bad unit (should be) like all electronics. Good customer service is just as important as the product itself. It's nice to know that a company stands behind their product.
