Slightly smaller than I expected. The zero calibration is not exactly accurate. I measured a 9 mm diameter. Caliber and micrometer give more or less the same reading. For my non-professional use and for the price, it's okay.

The seller, where high-quality packing of the goods? Where some bubble wrap? why was my product crushed? why rod micrometer misaligned? What is happening? RAM rotation Ter while I was not corrected? it's a precision instrument!
The MIC quality for the price!!! but a bent micrometer for the price....did I have to ask you to pack? do I need to take care of the product I bought? What is happening?
where is the button pack my stuff efficiently, so it does not railsa?
