Customer safety is important to us. We therefore call back Wiesel V4 charger and replace affected units free of charge with a new charger. In rare cases there is a risk of electric shock from units made in product batch 20141210. In case of failure, under no circumstances an electrically conductive object may be placed at the terminals of the charger. To protect our customers, we ask you not to use this device and return it to Lupine as soon as possible.
