I've been using the strata for 2 years now with no complaints. Its the longest I've used a wallet. I like it because it stays the same size. I no longer have the Costanza phenomenon to deal with. The strata is the smallest of the flipside line only carrying 5 cards with an exterior money clip, which is why I got it. I highly recommend it
When I am not at work, this is my two options for every day carry. Depending on what I am doing, where I am going, and even my mood. When I am at work, I can't carry "hardware" but I have other tools that I have at my disposal. Oh yeah, only thing missing is my Sunto watch.
