Just got my cases in finally, after 3 weeks. Much better quality than I was expecting, and definitely cool looking. A couple complaints though. One is that it's a major PITA to put on and take off. I hate feeling like I'm going to break my phone every time I take the case off (I'm looking at you, Poetic Atmosphere!). My other complaint, and this is a big one, is that it has some seriously wicked edges that make the phone a pretty uncomfortable to hold. For a phone that feels so nice in the hand, it's a shame to have a case on it that essentially kills that comfort altogether. I also have the Griffin Reveal which is a very similar design- not as cool looking as the Supcase but much more comfortable to hold. It's edges are a lot smoother and the material around the sides of the phone is a lot softer. The reveal is *almost* just as comfortable to hold as the naked phone, as it follows the contours of the phone very closely. The Supcase on the other hand focuses more on styling at the cost of those comfortable contours. If you want a case like this, ie. soft bumper around edges but clear plastic back, I'd recommend the Reveal over the Supcase. My $.02.
Edit: The Supcase has the dimple whereas the Reveal does not. I know somebody is bound to ask that question.
