For this price the dock for the Galaxy Tab is truly an impertinence! As described in other reviews no data / charging cable nor the corresponding HDMI connector is included. Prefer the docking station to use a video via HDMI to watch on the TV, the cable must be connected to load. I want the tab after connecting with my computer, so I have to take out of its holder and dig out the plug from the corner of the data cable! So in the final analysis you put yet again everything from and to, so I had not imagined at this price.
There is yet another quirk: is inserted, the tab in the docking station while the HDMI cable connected to the TV (and it is off), so the tab is no longer usable (it only jerky everything). Apparently the dock constantly trying to connect to the TV to produce and blocked the Tab. If the HDMI connector removed from the docking station everything runs smoothly!
A second star there because playing HD movies running completely smoothly!
