Ive used UBER cabs many times, their service was very good for me. Sometimes it takes a few minutes to reach me because of the traffic, otherwise its service is very easy to use.
There were some communication problems with me in Odisa state, but not with all drivers, many drivers knew Hindi or English.
They didnt charge me any extra rupees and not demanded any tips.
Drivers behavior with me was very friendly every time.
If you tell me to recommend for cabs for you, then Ill recommend you to use UBER cab.
