I've had one of these for a couple months now. I will say I am over all satisfied, but only because I seldom install the case. The slight pillowing does bother me a tiny bit, and prefer to run the iPhone naked. I like having the case around for special occasions only. After reassembling a few times to loosen it up, I get the feeling I could do so unlimited times, as long as it's done carefully and the seals inspected. Using a coin to wedge the corner open, the unit disassembles quite easily. I just like the knowledge the case is there if I need it, despite it not being perfect. I would buy it again, even for $80.
I wonder why they designed it with a pillowed screen. The foam and plastic spacers cause the pillowing, so they went to special pains to create the effect, but I wonder what purpose it serves other than reducing tactility.
