Just clean the inside of the protector and the phone with a eye glass cleaner, and that fixes it. Did with my OB defender anyway..
My Lunatik has the oil slick/rainbow effect going on so I will take it apart and clean the inside.
The directions tell you to clean the inside before assembly but I skipped it thinking that I did not touch the inside so it would be perfect from the factory.
Maybe there is a greasy film that needs to be removed? It appears to me that there is space between the two pieces of glass because I can make the rainbow move around with pressure.
Other than that, the case is really nice. It is considered dust proof, shock proof and water resistant. There is a marketing video on there web site and you tube.
Buttons - I hope the volume/home buttons break in a little because they are a little stiff for my liking. The power button is recessed but smooth and easy to operate. The mute button is a little hard to operate IMHO. I believe there was mention that the iPhone 4s cases mute button was to easy to accidentally engage so I believe they shortened the button which makes it harder to activate.
I would rather have it shortened than prone to accidental activations but maybe they should investigate a different mute switch altogether.
The rubber access flap for the lightning connector seems like it will tear off in time. It is just a rubber piece that is hinged by the same rubber. You just bend it back to access the port. I really like the LifeProof case lightning access door that is hinged with metal and snaps open and close. The rubber door is easy to get open and hold out of the way but it does want to snap back into place be default.
Weight - Just by feel I can tell that the iPhone 5 is heavier with this case. This case is some rugged protection with great aesthetics but it does add some feel to the phone. I forget how sleek, thin and light the iPhone 5 is without a case. Honestly, I almost think the phone feels to thin without a case.
Functionality - I like how the case is assembled with the screws and all but it makes it difficult to remove the case if needed. I have a Mophie on the way and would like to pull this case off and slap on my Mophie when my battery needs a boost. The installation design of the Lunatik will make this a chore! The bottom of the case has a big rubber backing for ant-slip/slide protection which is nice. The case sounds very good when making or receiving calls.
Price - I truly believe the case to be a little over priced. I think a reasonable price point would be $89. Still a premium price but not one that has me second guessing my purchase. If the case was truly waterproof, the price point of >$100 would apply.
