That's why I said to give a shot at contacting Caudabe customer support as it sounds like something is wrong with your case. I have both as well and I have no "separation" on my Veil. And they've given me replacements in the past for issues that are way more minor than what it seems you're describing. Literally the only other place where I've have had customer service respond as quickly and as nicely is at an Apple Store. I don't usually get gushy about stuff like this, but they are seriously responsive. No sense getting stuck not liking something you paid for.
I like the PowerSupport as well. I wish the Veil could wrap all four sides. But, like I said the PowerSupport is just too thick. Changes the feel of the phone completely And because of how glossy it is, it gets fingerprints and scratches really easily. I knew all this before I bought it, but it still amazes me how quickly that all happens. And for the price of one PowerSupport, I can almost buy 3 Veils. I get that it's a Japanese product, but holy cow that is a lot of money for the case. I'm a bit of a case addict, but if I had to buy just one case at that price point, I'd rather go with the official Apple case which is made of quality leather.
