Having dedicated my entire career to manufacturing, designing and using micrometers of almost every shape and size, these are my favorite non-digital friction drum micrometers. My second favorite would be Tesa/Brown and Sharpe, especially the Swiss versions. These microphones are expensive and in no way competitive in price with Mitutoyo. If you are on a budget, be sure to visit Mitutoyo. As a premium option I choose the 463 series micrometers. I gave them 4 stars only because of the price compared to other quality brands.
