I have the same case for about a month now. I removed the built in screen protector as soon as I opened the package, it came off easily but that damn glue residue was a real pain to clean and remove.
Anyway, the case does add some thickness and weight to the phone but it is built like a tank.
My NFC still works with it (at least with my washer and dryer) with the case on.
I haven't seen any rubbing on the phone from it, perhaps along the bezel but nothing noticeable.
This damn case is a pain in the ass to remove though, it's on there like cement, but once you know the trick, you get use to it.
I do like though that the case does make my phone look like it's from Battlestar Galactica with the cut corners. :highfive:
