When I ordered my Wife her Mighty Wallet, I purchased myself one as well (cos it was on Clearance) and for the fourth time now I have emptied my "World's Thinnest Wallet" and tried to use the Mighty Wallet but even after a few moments of using it in my back pocket I had to switch back.  Once you have spoiled yourself the luxury of the World's Thinnest Wallet, I must say it is HARD to try anything else. I might have to make a video to show you exactly what I'm talking about, but this is remarkable the difference.
