Review on 📏 Enhancing Accuracy and Efficiency with the Qfun Measuring Waterproof Electronic Micrometer by Robert Long

Overall I am very happy with this caliper. The display is large and easy to read. It turns on automatically when adjusting the caliper and turns off automatically after 5 minutes. It uses a widely available 3V CR2032 lithium battery. As long as it doesn't drain the battery when not in use like another digital caliper I've had (what a pain - I had to take the battery out after each use). I took off a star because the description said there was "a small screwdriver" in the box (required to open the bulky battery cover), but the screwdriver didn't come with my order. I contacted the seller and asked if they would forward the missing item. They answered, but in general they lied to me, so I had to buy a mini screwdriver myself. The advert still states that a small screwdriver is included. Aside from the lack of a mini screwdriver, this caliper is a quality tool.
