after the 3rd consecutive FSE I now have the Bury FSE "CV9040". For 2 weeks in operation: I'm thrilled. But it would be desirable, that would keep the Accu longer. The capacity is too low. Also belongs to the basic equipment, a hard charger. Only with the car charger cable is not at all that. I must let insert the ignition key so that the unit is charging for example. How funny is that? BUT: the technology is simply great (sorry).
