very good value for money, on the life and operational reliability I'm curious

The value for money is unbeatable, especially when you consider that the battery is on the capacity of her even slightly higher than the Nikon-original battery (durability remains to be seen) and the charger to both the 230 V socket and the 12- V vehicle socket can be operated in the car.

So why not 5 stars?
The charger is very hot in the 230 V operation while charging at one point. This is something I had not at all my previous digicam battery chargers in this form. So I'm curious how long the life will be hope and, above all, that nothing can happen. I'm not an electronics expert, but could not imagine that the manufacturer would defuse the problem, when he simply donated the corresponding component a heat sink or it would have slightly larger dimensions. Well, a CE mark is on it, I hope as I said, that therefore a certain reliability is ensured. However, if I had known decision about the heat development in the run, but would tend decided for another charger.
