Just got mine.
Looks cool, but I'm slightly worried: because it doesn't ~look~ like a standard wallet at first glance, I'm worried it might end up lost in a pile of papers on a desk, or get knocked in the trash, or just generally not get the elevated treatment a standard wallet would receive.
"Hey, have you seen a wallet around here?"
"No."
(I'll update this review in a couple months, after I actually use it for a bit.)
Update (6.26.2011)
---------------------
It's nice and thin, so sitting on a lump is never a problem. However, EVERY time I use the wallet (taking out cash or a credit car) I find myself having to reseat the cards inside. They are in constant danger of slipping out.
The lack of storage slots (there are four, but only a fool would use the outer two card-spitting ejector-slots) is another problem, forcing the user to stack cards. (Though the stacking somewhat tightens the wallet's grip on the cards.)
This is something I use everyday and really don't like at all, and I regret having kept it. (I'm shopping for a new one today.)
