I thought they were good until one night I took use of Uber from Milwaukee Airport. Before I selected what type of care service I wanted from Uber, I immediately got a phone call from an Uber Driver - which I thought was very odd as all other times they responded a few minutes AFTER I finished choosing the car type and then submitted. A black car - a Lincoln Towncar showed up. I was charged $55.00 just from the airport to West Allis. I was expecting to pay about $20.00 which is what I paid on the way to the airport 5 days earlier. After complaining to the company all they said was that I chose the Black expensive car - even though I never even had a chance to choose type of car on the APP - the company said they already paid the driver so they could not do anything about it. I think the driver knows how to intercept the signal as soon as you log into the APP - BEWARE!
