Q: The case I had didn't fit properly - the window obstructed the rightmost side of the display. You could shift it over, but it would always shift back. I don't know if they are all that way (maybe I got a bad one?), but I didn't want to buy another one to find out.

A: Negative

Q: This shirt was labeled Large, but it was more along the lines of XL to XXL. Unfortunately after paying extra shipping charges, I had to pay more shipping charges to return. I won't buy from this supplier again unless they offer free return shipping.
