Metal shell that wraps around nicely and back of the phone and gives it a compact and solid appearance! 2 drawbacks: - Lower cutout for the charger is too fine (does not work with all USB cables) which can be arranged with a lime (1 mm less and voila); - The steel hull prevents induction charging and above significantly reduces the reception 3G / 4G and WiFi which is quickly moving unpleasant (especially in rural areas). Otherwise, it's still the class!
