I just got the Skinomi carbon fiber skin in today and to be quite honest, I'm not too impressed. The quality of the skin itself is pretty good (seems to be 3M material) but two things bothered me about it. Firstly, even with a heatgun and careful smoothing the edges seem to catch on things so I'm not too sure how it'll last. Secondly, after application of the skin my phone's back started to creak quite a bit. Considering just how sticky the skin's backing is, I'm sure it's lifting the back plate enough for it to start creaking... prior to the skin, my phone had some flex in the back but no creaks. Overall? Not bad I guess, depending on what you were expecting this skin to do for you. Definitely good enough to use as a stopgap until better cases are released, IMO but long-term I'm not too sure how the edges will hold up.
