I have carried my Wally Micro with me for many years. But when I wanted to buy one for my partner both wallets were invalid. The first one I bought her was a "newer, improved" version with a wider elastic band and rounded corners. The wallet was not tight out of the box and the cards kept falling out. A year later I thought I would try again. I bought the same model as mine, the "older" version, and while the fit was slightly better, it still wasn't as snug as mine. We even left it under heavy books for days to try and wrinkle the skin. All in all it's a great, functional, minimalist piece that I use every day and really like, but quality control can be lacking.
