I've had the original MagSafe wallet for a full year (with 12 Mini), and the next time it falls off the phone will be the first. I took a flyer and got it, assuming it would be too limited and that I would either return or use only in very specific circumstances. But, instead, it's my regular wallet that's only been used twice in that time.I have never gotten the concept. Why would anyone want a mini wallet that can fall off of your phone? Why would you want to flash your wallet every time you take your phone out of your pocket?
I have my driver's license, credit card, and work ID as my 3 cards. I've discovered I really don't need cash on me, and I don't need all of these other cards that get used once a year. When I go to Costco - I swap the work ID for my (separate) Costco credit card. When I stay at a hotel, I swap my work ID for my hotel key.
It's been nice to travel so light!
