1. Comes with instructions in clear American English.2. Repeatable zero on arrival without adjustment.3. The thimble rotates smoothly across the range without binding.4. Fits into case when thimble is fully extended 1 inch. (Too bad my Starrett depth mic can't do that. What a pain!) The bottom of the foam is nice and stiff, but cut to fit a regular micrometer C-frame rather than this model's shorter shape , which allows for some movement inside , but much better than wooden boxes holding my Starrett sensors when they rattle around.7 . The blue plastic box is very sturdy and contains a real metal hinge pin. It doesn't get squashed in a tool box. mower if that's your standard for buying precision tools.) I'm definitely happy with this price point.
