5 stars only ....

because it is a Ladegegerät that simple battery's load, nothing more.
The device I as a replacement for another device bekmmen that did not work. I have to say the seller is great at trying to satisfy the customer, for an extra 5 *****
With my first set I just wanted to say that one can not do much for the erwartem günstgen price. You put a 2,4,6 or 8 battery's. Only works in pairs, as in each bay 2 battery's must be the same capacity. A battery does not work alone. Then you wait until the LED turns green, that was it.
Display as V, mAh, charging time, mA or charge state does not exist.
If you want his battery's also maintain, you should already buy a charger which test function Refresh function, status display, etc. contains.
The course costs more.

Anyway, for ease of use, price and simple handlings in this performance class 5 stars
