Having waited a month for my iPhone 5s gold to arrive, the 2 things I didn't want to do were:
1 - damage my precious new phone
2 - cover the sought-after gold casing
So this case was an obvious choice. I didn't want a solid plastic case as from experience these are extremely difficult to put on and take off and they snap extremely easily around the port holes. This case is made of very firm gel, so it's a solid enough structure whilst maintaining enough flexibility to put on/take off your device.
The case is very subtle when on the phone whilst feeling like it would provide sufficient protection. It has a slight lip over the front should your beloved phone happen to land face down.
One minor gripe is that air does trap down the back of the case, leaving some visible air bubbles, but this is quite subtle and a small price to pay for an otherwise excellent case.
UPDATE 28/02/2014: I wanted to update to say that after around 2-3 months of using this case, it became quite discoloured, to a smokey brown shade. I am not really sure what caused this specifically, just general use. It doesn't look terrible, just not as clear and pretty as new. After 4 months I decided to purchase a new clear case as I wanted my phone to look fresh again.
