I have been using Mitutoyo calipers for about 45 years. I took good care of it - used it almost every day during that time. While not as accurate as a micron, it was close and always good enough for my needs. After purchasing this Kraftler digital caliper, I compared it to my classic Mitutoyo with a 1-2-3 block set. In any case, Craftler is even more accurate than my old Mitutoyo. And I paid less for it than I did for Mitutoyo 45 years ago. Considering inflation, this was a fantastic deal. And I'm really addicted to the ease of digital display to convert between inches and metric. Instead, I will use it every day.
