Very unreliable. Late even with a few hours advance notice. I called when driver 5 minutes late and was told driver on route should be any moment. At 11 minutes late the driver called me like he was just going to head my way and said 6-7 minutes. I said don't bother since I knew it would be more like 10-15 min. Not professional. I was against Uber but now I understand why they exist. Maybe they know how to tell time. Never will I rely on a cab for something important. Ruined my plans. So very disappointing and huge inconvenience.
