2nd shelf ordered, after the return of a first Faulty at the slab (dust in the middle of the screen) And that is second command gave me satisfaction by the time the battery discharges. Then impossible to charge the battery. No reactivity with the charger was connected. The charger was operating well since he tested on another shelf ... So HS shelf in just 12 hours. Not very serious level fabriquation. By cons, big reactivity service level :)
