Charging station very "plünnig"

This battery, charger kit not meet my requirement. The charger makes a not particularly stable impression. It is very easy and just for use in the car, I expect a little more stability to fast one has yet put on it by mistake or the like. Moreover, the battery is unstable, so that it is not accommodated safely while driving.
The Ladekaben however, make a solid impression. However, grad the charging cradle, the main reason for an acquisition.
The handling is very simple and despite lack of instructions or less "self-explanatory".
I would not buy it again despite the low price.
