I didn't have any problems with TouchID. Well, no more problems than before at least. You can see where there's a membrane over the TouchID home button and the "pillowing" around it. I could NOT live with a built in screen protector if it was that bad most of the time. There's also a similar membrane over the flash LEDs but not the camera lens itself. Edited 30 minutes later: having a bit more trouble with TouchID...
Thanks for the review

I'm using the original Nuud case for the iPhone 5 with my 5S right now, so I'm not using TouchID at all. I'm wondering if you try to re-train it with the case on if that would help. The pillowing effect doesn't look great, but I think I can live with it for TouchID to work.
I believe that the screen protector on the Fre cases is made from a different material than what's covering the home button on this case and that works a bit better as a screen protector, but it's still not idea. I definitely prefer the uncovered screen on the Nuud case.
Also didn't expect the silent switch to be reversed (down for ringer and up for silent) but I guess it makes sense.
Yeah, that takes a little getting used to, but it's not a problem after a while.
Definitely wouldn't buy it a full price, unless a watertight case is absolutely necessary. But at $110 for the case, car mount, and armband, it's not such a bad deal.
There are definitely some compromises to using a waterproof case. I've been using the lifeproof cases since my iPhone 4 and I love the convenience... I can take the phone in the pool with me when I'm on call and I don't have to worry about my phone out in the rain and if the phone gets dirty or something spills on it then I can just take it to the sink and wash it off. But waterproof cases aren't for everyone.
And WTF the amazon basic lightning cables will not work with it. The ATT car charger cable BETTER work with it.
The iPhone 5 cases are actually much better as far as third party cables than the iPhone 4/4S cases were. The iPhone 4/4S cases pretty much wouldn't take any cable but an original apple cable... and even the apple cable barely fit. With the 5/5S cases they've made the opening a bit larger than the apple cable, but clearly not large enough for all third party cables. Unfortunately I'm not sure they could make it much larger and still allow it to have a watertight seal without increasing the thickness of the case.

Control center worked fine for most of the evening, and then when I got off work and went to my car I had trouble for a little bit. Shouldn't be a problem for the most part though.
It's hard to tell from the pictures, but it looks like the bezel around screen slopes a bit more than the bezel on the iPhone 5 Nuud case and I'm sure that's to help with the control center. It's possible to activate the control center reliably with the iPhone 5 case, but it's not as easy as it should be. Hopefully this helps
The back COULD scratch easily if it's made out of the same plastic as say, the Poetic ThinShell in clear. It's not likely though as the back is recessed.
The back on my iPhone 5 Nuud case is still in good shape even after 5 or 6 months. There are definitely a few marks and light scratches if you look in the right light, but they're not very noticeable. I keep my phone in the belt holster, so I think that helps to keep it in good shape too. If you put the phone in a purse or a pocket with keys and such then it might get scratched more easily.
