I used to have good experiences with similar looking cheap calipers but not this time. What I received is the same at first glance but poorly assembled: the plastic parts do not quite fit together and have significant play, it also came in a box instead of a case and most importantly it doesn't work. As you move the dial across the ruler, the measurements will oscillate between -999 and 999mm for a few seconds, until they randomly stop at a wild value that has nothing to do with their actual position. This time I got what I paid for I think
