I wouldn't really call it "high quality", but it does the job, better than expected for the price. It makes this squeaky noise when you open and close it, it's somewhat annoying, but it is very accurate, and I mean like 0.1mm accurate. I wanted to have at least one caliper independent of those button batteries, happy with this one. 0.1 mm repeatability, not bad for few bucks. Oh, you can open it to adjust, and it's got this paper dial inside, so, you don't wanna open it with oily hands or in dirty conditions, such as garage. So, yeah - paper dial and the squeaky noise, but very accurate.
very poor quality
