Uber sucks. I used them twice and I was obercharged both times. It was a big headache to get refund. A couple of my friend used uber too-they had the same problem like me. Both time my drivers didn't know where they were going too. One of them at least was nice, but the other was rude and even cursed me. Uber offers $10-$20 free ride in the beginning. That's the way they get people. There is nothing free in life. One or another way YOU will pay for it. I'll never use uber again.
