I still have my first generation iPhone, and the second I got it, I equipped it with an iSkin Revo. So albeit not a iSkin Revo2, I can give you a little review on the original.
It's f*$king amazing. I've had no problems with this case what-so-ever. It's beautiful, great feeling, incredibly protective, and well worth the money.
They boast a three-section protective screen film, one of which is a tinter so people can't on-look what you're iPhoneing, and even through the three layers of film, the iPhone has no problem sensing your touch just as it would if it was naked.
On top of that, the whole iPhone is cased in a alleged anti-microbe rubber, where as no germ can live on it, or so they say. The rubber it's self has a hole for the camera lens (which is as well protected by a plastic lens). The only places where the iPhone it's self can actually be physically touched is the charging dock plug-in (which is covered by a removable tab for the Revo and a flippable tab for the Revo2) and the ear-piece speaker, which I think is also covered by a film in the Revo2 but not sure. Even the audio headphone jack is covered by a flippable rubber tab.
Last but not least is a fun little hard-plastic "ViSOR" as they call it. It's docked on the back of the iPhone when you're not using it but you can easily snap it off and snap it on the front for a hard-plastic cover onto the front of the iPhone over the three layers of film, for an "un-penetrable" defense.
In short, it's an absolutely amazing case. I've used the original Revo on my iPhone since I've got it like I said, and under-neath it's still as good as new! Have no doubts when deciding to purchase this case, considering the Revo2 is practically the same thing only even more-so, it's a great buy.
But I'm not going to lie to you. Now that I think about it, I can think of two cons about the iSkin.
1. You can no longer use the "docking" little mechanism they give you with the iPhone when charging it, since the size of the iPhone no longer fits. However, iPod Speaker Systems have inner-changeable dock sizes, so that's no problem.
2. It does stick to your pockets
BUT! You can buy the bundle package for 10 bucks more and get the belt-clip. I always feel it's kinda geeky and pretentious to have a belt-clip though.
