Hey vacay, I saw you asked yesterday about this. So I had went 50miles away to the nearest Apple store that still have the Belkin in stock and I had ordered the last one.
It was bad, the drive on a Sunday was not fun as expected but I made it almost to closing time which is 6pm on a Sunday. I was surprised to see the store packed with little room to move around, maybe this is normal but this is my first time going to the Apple store. So I had to flagged down someone for help and asked that I wait, so I did. Overall it was a great experience.
They installed the belkin using this machine that they did in front of me. It was almost flawless, have problem with the bottom of the phone seems not to have enough glue or something it won’t stay down. Overall it is a great quality screen protector and felt like the phone screen itself. Also there is no rainbow effect, the surrounding edges is matted kinda like cauterized effect, no light from it. And I had google rainbow effect on screen protector, this belkin is good
