Been using this case over a month now and zero issues. For those worried about it "permanently damaging the device" as was reported earlier, when you remove it, you can see the imprint of the foam backing a little bit but it comes right off, as expected with a glass back. I was able to rub it off with my finger in a matter of seconds, total nothingburger.
My phone has also taken a few spills, some of them face first. Zero damage to the phone or the case.
My only gripe after using it for these past weeks is that it's a pain to remove. You can't just pop it out, you have to remove the outer shell first. For us men who don't have fingernails, this can be very frustrating. Fortunately most people won't have to remove their cases all that often, I just like to try different prepaid carriers which involves switching SIMs more often than most would. It has offered ample protection for my phone and that's what counts.
