Without the lettering it looks exactly like a couple of digital depth gauges I bought on E-Bay. They are offered there from time to time by the same guy. I'm sure they came from the same Chinese factory.
Mine have a nice finish and work well. The 8" has run on the original battery for about 2.5 years. It seems to compare well with other calipers and my mike. The 12" had a defective lock screw and the seller does not answer my e-mails. But it is OK otherwise. I gave up as I hope to use it as a readout on the lathe and will never need to lock it.
Make it fit.
You can't win and there is a penalty for trying!
