Third party case makers seem to be having all sorts of fit problems with the Air. Here’s what I’ve experienced so far:
Arc Pulse: bottom is too tight, doesn’t sit flush against the phone
Pitaka Ultra-Slim: Loose upper right corner, metal camera frame hits the glass plateau
Süti Phoneback: Top doesn’t lay flush against the phone, rattles
Andar Aspen: Bulge at camera control, USB cutout is off center
Only the Apple and Beats cases fit correctly. Frankly, I’m getting tired of these case lotteries and arguing with CS reps about their defective products (you’re not holding it right… lol). Perhaps I’ll just stick with the Apple cases this year and call it good.
