I first used them a few years ago and they were ok, but now every car you try to book in Philadelphia has an exorbitant security deposit that will not be refunded to you for over a week! If you make money as an Uber driver, that isn't going to work. Also, they no longer offer telephone support. The app wouldn't let me close a trip and I got charged $50 because I couldn't reach anyone on the phone. Eventually my money was returned a few days later, but I shouldn't have had to go thru that. Not a good option anymore for Uber drivers!
