The DS is handled properly and if one takes out the inner shell that fits SGN2 even with Mumbi sleeve top. The plugging of replacement batteries, however, must be practiced only a little. The charging indicator for the spare battery could light up more or be greater (but which is bleating at a high level). The USB cable is long enough, and an AC adapter, there are also (heart what you want more).
Update 05/08/2014: since last undock the smartphone will insert no longer starts after you in the dock. Probably here a contact is broken. So I can only invite the spare battery into the dock :-( After 6 months, there is nothing more to "guarantee" ...
