This bumper metal - not a case as shown in the Amazon description - is fine and well finished. The article comes with a mini screwdriver for opening / closing the bumper on the OPO; and 2 extra screws. Everything is accessible, including the location of the SIM card. The buttons always respond well. Aesthetically, I do not find that the best effect. Although this is seen is added, but it is ultimately secondary, because it protects the smartphone. What bothers me more is that the grip becomes difficult. It is now dangerous to use the One Plus One-hand (it was not already obvious before!). The size is ultimately greater than some hull. This product, without being bad, does not convince me. It is a matter of taste.
