I ordered the Quattro T-4 from Ivyskin on 12/3 after reading the initial reviews about this case. It had all the elements that I wanted, the faceplate that covers the phone, a sleak and not bulky exterior with a non-slippery grip. I received the case via priority mail ($11 shipping) and was very excited about the case, it looked amazing in it's solid retail container. I was excited and put the iPhone into the case immediately and that was when i saw the rainbowing effect on the left side of the screen. It wasn't just a little bit as some have mentioned in the black corners of the phone but it covered the entire left side of the phone from top to bottom. I emailed customer service and they said that is unusual and i sent it back. I had to pay for the shipping to get it back to Ivyskin which costed me another $6. The exchange process was smooth and i received the replacement case in the mail today but only to find this case has the rainbowing effect on the ENTIRE screen AND to top it off.. the case doesn't close tightly, it now has a gap where the bottom/back side meets the front side and allows dust to get in. I bit frustrated with the entire process. It's taken over 17 days now and i still have a case that doesn't feel like it's worth the cost.
