Concerning the phone housing protection, I took red, which gives a very nice effect with the Galaxy S5 black. The assembly is properly fitted. The tower and the edges of the phone are well protected, and there are small rubber pads on the inside of the protective tape, enough to cushion and distribute the pressure in case of impact. The side buttons are very precise, and walk perfectly well. The great advantage of this protection is its compatibility with both the standard rear shell, the shell loading no induction, slightly thicker. The Red anodizing looks solid, I'll see with time.
I am very pleased with this set.

Changing my review:
I put 5 stars, I withdrew two: I ordered the red model once. Very pleased (comment above). So I also ordered the silver pattern and blue pattern. Disappointment, manufacturing is different, coarser coats, the thicker border, buttons so they stand out was perfectly integrated on the first, it is now impossible to open the hatch of the sealing USB3 socket. The main functions is still filled, and all holds well. Hoping it so long as it is a plastic foam film that keeps the phone (rubber spacers on the first model).
