Average Reviews:
(More customer reviews)This looked well-made at first glance only. The main rail had about 5mm of total curvature, the inner rail had about 1mm of play, and the end-stop was crooked. The motion is also rough and drifts unless you lock it down. I would only trust it to a few hundredths, getting worse as you approach the terminal length, because of the bowed rail.
If this is typical assembly quality, the carrying case is (relatively) the best thing about this product. They should downgrade the rated accuracy for slack in the rails. It's probably based on the read-head's potential on a much better frame.
Those who give this (and other cheap calipers) good reviews may not have used "real" calipers for reference. You can't know something is "accurate" unless you have a benchmark. I just took a chance on it for simple shop work.

When you require exact measuring, you reach for a caliper. But an accurate measurement is meaningless if you can't read it accurately. This caliper takes an essential tool into the 21st century with an extra-large LCD digital readout for exact internal and outside measurements accurate to .001". Instantly converts from SAE or Metric, the display can be zeroed at any point on the slide. Machine-grooved thumb-roll mechanism and position lock for sure adjustment. Hardened stainless steel shaft with depth-measurement probe, precision ground jaws. On-off switch with auto-off, two long-life batteries included (one extra).
