USB Charging Dock Station + US Plug Power Adapter + USB Cable for iPhone 4

Pros: Packaged well and nice form factor. Charges iPhone and line-out works as advertised. Was iPhone 4 compatible without going into airport mode. The dock itself was a nice weight.

Cons: I felt that the following were problems: -No back support for iPhone when docked. iPhone felt a little unstable in it. -Interference problems causes severe line-out buzzing -Charging has faint high pitch buzz

Other: Although cheap, I would not recommend. You should get the dock without line-out instead.

Pros: It's heavy and stands solid on desk.

Cons: - iPhones speakers doesn't work when its on this dock. You can't hear a ringtone, music, etc while its charging! You have to use an external speaker which is always on for not missing a call or SMS! - Very Cheap Material Quality, - It's cavity is too big for iPhone4. Telephone doesn't stand still and you can move it easily while its connected. You can hear the cracking sounds from the dock. It can easily be broken! - Cable is shorter then original iPhone charger.

Other: Don't buy it!
