Fast shipping. I tested it for accuracy with another caliper, and it appears accurate. It slides smoothly. It feels sturdy. All buttons work. One thing to know if measuring in Imperial (inches)... like almost all others, it will give the measurement in decimals, but then you have to convert to determine, what fraction of an inch. If 20mm.... What fraction of an inch is that? first divide by 25.4 (number of mm in 1 inch) 20mm / 25.4 = 0.7874 inch then look on a conversion table to find it equals 25/32 of an inch. Metric is simple. Enjoy.
