I've had an aluminum bumper case on now for about a week.
No loss of reception or data and I do not use NFC.

So you're confirming that you do lose NFC? Also, for $10-$15, its not a bad deal to try out. Does this case have any felt on the inside of the case to protect from scratching the actual phone?
