I like the Capsule Rebel a lot (I have the yellow/black) but I am going to return it to the store today. As cool as the thing looks I don't like how its sorta loose at the bottom (and its brand new). Also it put a tiny scratch on the bezel the first time I took it off. But hey its just the bezel, in 2 years i'm sure the bezel is gonna look dull and grey. The other thing is the spine already has scuff marks on it and I did not really do much with this case. Granted this is a given its going to scuff so just keep that in mind if you really care about "looks". Silicone seems to stretch very easily so...i like how it comes with a lot of things. But i almost lost the charger/sync cover, it just fell off. I'm unsure of the drop protection it provides. I am paranoid about this because my friends dropped his and his iPhone went byebye. A co-worker dropped their iPhone and cracked the glass even with a case on it so... I really like the concept and idea of the Rebel Cap but I guess its not for me.
I also have a Vaja iVolution SP that looks awesome (orange/white) but function wise i don't like the flip at all. It also scratched the back of my phone (especially the logo) and I have no idea how. The leather is soft, etc...
I keep going back to the Otterbox "beast" defender. Its like I want to find something better than the Otterbox but so far nada. The best protection for the iPhone. But I also worry about the silicone stretching or ripping at spots. But Otterbox assured me when this happens they will send me a new silicone cover no ? asked. Very good customer service. They just shipped me out a whole new plastic case because mine had a smudge on the membrane that would not wipe away. Good CS.
