Confession: I'm a measurement tool junky. So I threw the dice on these calipers purchased through AliExpress. I've had them for about a month now & actually find myself grabbing them quite often. So far so good. Not as accurate as snap gages or ID/bore gages but very quick to use for the progression boring until you get to the critical ID & break out the expensive stuff. The repeatability & accuracy is actually pretty good (as digi-cals go). These jaws are more intended for this kind of work & I find them a bit better suited vs. verniers (which are also limited to measuring shallow depth).
Never heard of Shahe brand before, but kind of reminds me of Asimeto... maybe even a bit nicer. Battery not included, its an SR44. Only 3 digits (0.001") not half-thou (0.xxxx5"). Unlike verniers which zero with jaws closed, on these you 'zero' to known ID, say a 1.000" ID standard. Then anything you measure is additive to that datum.
