I had ordered 3 pieces. At first I was a bit skeptical but the delivery (free delivery!) Was on time and to my pleasant surprise positive functioned all 3 Chargers properly and have since always working and working until now with no problems! But (Care must be taken that the Chargers not to overload! The delivered chargers were gekenntzeichnet with 700 mA output current and I've found that the Chargers to 400 mA current load are very stable and only from a current load of more than 550 mA are unstable and warmer ! Therefore, my advice, the Chargers with no more than a maximum of 400 mA to charge then they will serve you well!) The price is unbeatable unbeatable very cheap and the shipping was also free of charge! For that I would even give more than 5 stars! My recommendation is for sure!
