I bought the version without the open circle in the center and light brown. Perfectly fits my asus zenfone 2 (ZE551ML) size 5.5 'leaves accessed the various connections and speakers. The shell protects both angles and the interior is velvety to avoid damaging the glass of the screen. The hull is fine enough, especially as the zenfone 2 is domed, rather thick and heavy compared to other competitors, but for its price it's a great phone! I bought a share of plastic films for the screen Acetech sold on amazon that go great as well (even if I have me back for installation without air bubbles and other dust) Only flat, a small "beak" on the valve would have been helpful to securely hold the flap closed at all times, but deep in my bag with the rest of the bazaar over it does not move. Good buy overall and good price / quality ratio
