I schefuled a pickup on Miami Beach waited much longer than was quoted on the map. The map kept changing time to a longer period. After a while I called the driver to see where he was and he said in Spanish that he didn't speak English. I canceled the trip and tried to schedule another and the price went from $16 to $43. I called Central taxi and had a car in 3 minutes for less money. I seriously doubt I'll use Uber again.
