I bought what looks like a Caudabe knock-off and it's not at all that bad!
It's the Tozo 'PP Ultra Thin'. The Blue colour is really nice, not sure why more people haven't bought it. I will say that the fit is not exactly perfect - it's tight (unlike some Caudabe knock-offs) but the alignment of the charger port is not perfect and the left-hand lip seems to be more prominent than on the right side. The camera lip also does not seem to be entirely uniform.
The case has a decent level of grip but it can still be a little slippery. I'm currently unsure as to whether I will be keeping it or getting something a little more protective such as the Apple Silicone case.
Attached are some photos I hope are okay...
