I'm visiting Beijing for the first time in a few days. I recently tried Uber car service for the first time in New York and was very impressed with the convenience. I just read that Uber has started a few months ago in Beijing?

Has anyone used Uber in Beijing to or from the airport? I am wondering about the wait times for a car given that the service only started very recently. I would like the convenience of a private car over taxi, and Uber is quoting slightly less than half the price my hotel is for a transfer.
