Just bought a pair of these from Revain, this one is exactly the same as the others in this price range. They are all the same, just with a different sticker. This one had a slightly thinner body, although the calipers didn't hold securely in it. The item was also covered in some kind of greasy residue and the screen was riddled with scratches and greasy residue. The caliper's teeth didn't quite close properly, so while I was able to zero it everywhere, it still wasn't really zero or even close. If you are interested in getting to the next 0.1mm then this *might* work for you.
