I won't be returning them but I'm a little disappointed. Part of the digital display is thicker than I expected. There is a cutout on the top for a USB port, but it isn't. That's probably why the display is so thick: it's designed to hold more electronics than it contains. It seems that the case was not specifically designed for this version. The calipers do not fit tightly in the slot and tend to engage randomly when stored. Also, is there an extra indentation for what looks like a pen? I'll just throw it away. The stainless steel case is made of 400 series stainless steel for its magnetic properties. The accuracy grade listed in the description is only for 0-75mm (0-3"). Also, I'm sure accuracy will suffer. Neither of these issues is a Deal breaker for a $35 caliper But it looks like he's offering nothing but $15-20 calipers on Revain.
