The second charging experimental unit was defective - free replacement is satisfactory

A week ago, right after your purchase, the shop of my Navis worked. A week later, the second charging attempt, nothing went (to the charger lit the pilot light is not, in Navi no external power has been displayed). I am the third customer that reports this problem. Because of the low price I discard the appliance and buy myself from another manufacturer, a new charger.
On 08/11/2011 I received for free and unbureaucratic a new charger; This also works in the second charging properly (I must therefore buy a charger from another manufacturer). Thanks to the supplier HandyNow. If the battery charger operates further, I am completely satisfied with it.
