Good: ? Mistake. ? It's supposed to work over the Pi display cable? Bad: Displays nothing. Shame: It killed my old Raspberry Pi 2. I thought it was just a coincidence/failure of the old Pi. But I got the same result after connecting another pi3. Now I only have 1 Pi left and I don't want to risk killing it and connecting that shield too. I risked it on this screen (there was only 1 rating). It was a costly mistake. It also looks like it was returned, the cable was twisted and didn't look new.
