OK, so am on the way home after 3 days in Mumbai. The "el cheap" prepaid cab from the airport to my hotel on Marine Drive was really bad, and overpriced, so I decided to skip cabs and Uber around the city during my stay there. Since Uber is new in Mumbai, I thought I would share a few observations.

Its very hit and miss. The Uber app will show lots of cars in the area for both UberBlack and UberX, but when you request one, they magically all disappear and you have to wait 10-15 minutes for a car.

I had several cancel on me within minutes of confirming, for whatever reason.

I used only UberBlack cars, but they were ratty Suzuki Swifts with roll up windows. Nothing even close to resembling a nice car.

On every single occasion, the cars would head off in the wrong direction. I tried calling and SMSing the drivers to clarify my location, but that did not work. No responses. I got one guy on the phone and he sounded very shady. I cancelled that request.

Rates were pretty good.... about on par with regular cabs, and a step up in quality.

Overall worth it, I would say, but keep your expectations very low.
