It has all of the things that I look for in a case. The fabric gives it the rare combo of good grip and easy to slide into/out of your pockets. It's very low-profile which probably limits how well it would protect your phone if dropped. I personally prefer the low-profile over a bulky protective case.
Another huge plus is that the auxiliary cable in my car plugs into it without having to drill out a larger hole like I've done on past cases.
Summary of pros: Good grip, easy in/out of pockets, nice looking, affordable, aux cable fits.
Summary of cons: Probably doesn't offer much drop protection
