Revain Show Ad fits all three. Surface Pro 4/5/6. The packaging shown upon receipt is for Pro 5/6 only. But the packaging breaks, it's the device itself that doesn't match the Pro 4. The USB and Micro B are further apart than the Pro 4. The Cateck will need to be modified to add them or I think many other returns are expected. I was not able to rate this device as it would not connect to the Pro 4 as shown in the picture. I'm a little pissed off because I'm doing DFM for the Cateck marketing team and I'm not getting paid for it. technical community.
