they're probably far from as acurate as an old school caliper. it's a fairly new thing that cheap calipers (digital and otherwise) have started getting made.
that said, for 3d printing...the cheapos are usually "good enough"
Where's my Vernier gang at?!?!
Although my god, even a halfway decent set of dial calipers is extremely satisfying to use.
There's a great teardown on Big Clive's YT channel. https://www.youtube.com/watch?v=fKSSY1gzCEs
Really interesting just how accurate they are, and they don't require professional calibration over time (from what I understand).
