Review on Millimeter Conversion Micrometer: High-precision Electronic Measuring Tool by Maurice Stavros

Very happy with it. I got it mainly because of my interest in watches and wanted to find a way to measure them without damaging them with a sharp steel caliper. It turns on automatically, which I thought was cool. It seems very durable, I think it's made out of some kind of carbon fiber rather than flimsy plastic. Seems perfect for measuring anything fragile you don't want to scratch or damage. Excellent price and quality.
