A good solution to protect Nexus 5

I use it since May 2014.
Although at first the product seem somewhat average, it is clear that it is still in very good condition 4 months later.
My phone has undergone several the falls on hard ground during this period, no damage.
Its main drawback, also linked to the nexus 5: tilting the game to access the screen behind the phone to keep it a hand, sometimes the phone detects the magnetic part which lock / delock the phone, locking the screen This can be quite annoying.
