Review on 📷 AmScope MU1403-CK 14 Megapixel Live Video USB 3.0 Microscope Camera with Digital Imaging & Calibration Kit by Kevin Epstein

This calibration tool is simply awful. The digital interface is clunky and hard to use, and the results are unreliable. The only good thing about it is that it comes with a nice carrying case. The downside is that you'll never want to use it again, even if you're working with electronics.
