I used UBER to take me from MIA to my home in Miami Beach, the car took 35 mins to arrive to the terminal.
The driver that showed up was probably around 21, dressed in shorts, sandals and reeked of marijuana (did not smell it until a few minutes into ride - he had sprayed something in the car just before we got in), he got lost even though he was using a mapping APP and I was directing him.
The car he was driving was a Chrysler 300, it had huge ghetto rims, I was seriously mortified being dropped off at my house. The car also had a huge speaker in the trunk, thank God I only had a small case otherwise it would not have fit and I would have needed to call a regular cab.
I will not use them again, I did not feel safe and it was just a few bucks cheaper than a regular cab or car service.
