I just received a Secrid with the leather flap in vintage chocolate as a Christmas gift from my sister. So far, I think I like it. The card ejection mechanism is downright cool, and it has RFID blocking, also. Since I typically carry 4-5 cards, that also means I'd have a slot open for hotel keycard. The additional pockets, etc. could mean I can carry maybe a few business cards and stash my receipts, rather than just keeping them loose in my back pocket.

Downside is that it's not as slim as my leather card case (looks like this one, with 2 slots on either side and a center pocket). I'm a front pocket person anyway, but there is no way I could live with this thing in my back pocket. I am already a little annoyed at the slightly larger outline in makes when in the front pocket, but I'm sure I can get over that.

I haven't taken it to the airport and tried in a WTMD yet (that's next week), so any feedback on that would be helpful. It's a big chunk of aluminum, so I expect it would set off the metal detector. I'll still try it next week and report back my own experience.

EDIT: Turns out the card slots in the leather piece are not wide enough for my business cards. They do fit in the plastic cash section, but I'll have to see how annoying it is to have both cash and business cards in there. Otherwise, I'll ditch the business cards. Sidenote: that plastic cash flap gets really dusty!
