I had a similiar checkbook holder (Wilson Leather) and after three years it started to fall apart. I bought this and thought, "wow, this looks sharp". Only after a day I started to regret the purchase, it is super slippery.  The previous wallet was Nubuck leather and was instantly softer and "grippier"; I never had to worry about it falling out of my pocket (I always keep it in my front pocket). I wonder if there is anything I can do to make it less slippery, besides running it under a sander.

UPDATE 7-15-2017:

I still have this and use it daily since I bought it. It's still slippery. But for it being over seven years old, not too shabby, almost BIFL! I would buy it again.
