So I'm looking for a super slim back cover for my iPad Mini 3. I had a Switcheasy Coverbuddy, but it's pretty thick. I have the ultra slim PowerSupport for my iPhone 6, but it looks like they have the hard plastic versions for the iPad, which are significantly thicker. What do you recommend? - Protection isn't as important as slimness - Must be compatible with Apple's smart cover - The thinner the better - As much of the corners\edges covered as possibly Seeing a few, but most get poor\mixed reviews.
