Wrong product description, otherwise okay.

First: as already noted by other reviewers: The item description is incorrect. The part has to synchronize only one current input, one that's not. But the unit was not even thought to myself, therefore bothers me is not so much. It should stop standing only on the sideboard and keep our hand and invite this Iphone.

But that we were already talking about the second problem: The device is supplied different dock adapters (small plastic cups) in order to guarantee a safe stand of the respective device in the charging station. The package includes: Clasic Ipod, Nano G5, iPhone 3G / 3GS and iPhone 4, as well as a larger part, with which one the rear cargo space for an iPad can prepare (presumably iPad 1). If you own but as my wife and I two iPhone 3GS, you're already ready. The iPhone is even without the plastic part well on the dock connector, but just not so sure. How well that keeps on permanent remains to be seen.
Unfortunately, the device is also quite easy (stop is made of plastic). So you also, the device must always hold, if you want to take out the Iphone.
