One of the best part about these cases is that they're stylish and highly customizable. I used a customized piece of artwork that I loved for my case, but they have a fantastic selection of unique artwork on the website as well. They're always getting new artwork in too. When you purchase one of their cases, it also comes with a free matching wallpaper.
Though it's a fashionable case, form does indeed follow function. The cases are made out of solid plastic, so they feel a little different compared to the soft, cushioning cases you can buy at mall kiosks or at cell phone stores. They are also really thin and compact. However, they're incredibly durable. My phone had one big fall and it cracked the case, but the phone had absolutely no damage. The crack never got bigger either, even after some subsequent falls. If anything, it just proved to me that the case was absorbing the shock of the fall rather than the phone itself.
Really, the only disadvantage to this case is that it's not waterproof like some other iPhone cases. Honestly though, I haven't found myself in too many situations where the waterproof feature was necessary.
This case comes highly recommended from me.
