The Caliper makes a high impression, the display is easy to read. The legs include opaque. Unfortunately, the built-in battery was empty. With the included spare battery they became operational. The repeatability is very good with +/- 0.01mm. A back and forth of the rotor does not turn on the teaching, but I did not see it necessarily as a disadvantage. However, the switched-on teaching also does not automatically. Here attention must be given. It is delivered in a plastic case with formed inner workings of rigid foam. All in all for the price a good deal. A star deduction there because no existing automatic shutdown.
