I bought 6 raspberry in my order 165113, when I ´ve tested all raspberry there´s one raspberry doesn´t work. The battery is with blue light and when you switch on the raspberry in the battery the ligth is off at the moment and it doesn´t start to work. I believe the raspberry is short-circuit.
We have bought more thatn 30 units and it´s the firts time that this happen. I´d like to know how must to order the replacement.
