I bought two of the chargers. One of them was defective. I have the charger immediately returned on 24.04.2013 again, with a request for compensation. Unfortunately, I have not yet received compensation to date. When I asked at the 12.05.2013 I was told that you have sent the Ladegrät for testing of the defect to the manufacturer! As a final text of the email you wrote: "Should the manufacturer not defective notice, costs for unauthorized removal of defects request to be paid." You NB: These are a product of 3.81! For me, Lets-sell is anything but customer-oriented!
