Yes, that's all it does is hold your phone and charge it. It slides freely about the car, has no external outputs, and leaves your screen in standard view mode.
Not every shopping decision on earth is price driven. It's the ease of use and clean install in the car that is the selling point. You dont have to worry about "get in, adjust off brand dock to fit case, find wire which is surely on the floor somewhere, plug it into the phone, go to apps, run car mode. Then you park the car, unplug, stow away the charger cable, exit car mode blah blah blah blah."
With this you get in your car, put it in; park the car, take it out. No worries, very easy. And for those of us who like to keep our cars clean, this can allow for a very nice install with few unsightly wires by wiring it out of the way. Not to mention it was designed to fit my case, and most likely will have pretty solid build quality.
I don't think anybody here is forcing you to buy it. I bought it, and I think many others will. Companies do have to make money, you just dont have to give it to them.
PS: hail to the redskins.
