Uber is a really useful and easy to use taxi service, I live in Kolkata, I find this really helpful.
Without wasting much time, I am going directly to the pros and cons of UBER:
Uber provides a free ride for any new user with a referal code, and also provides many free rides with sharing refer ids, when ever anyone enter your refer id, both of you and him get free rides.
It have many paying options, like cash, debit card, paytm and even airtel money.
3.Their drivers are friendly, and service is easy to use.
Cons:
Uber is not available everywhere, this is a major problem.
Sometimes Uber does not give cash option for new accounts.
In short, I find Uber helpful and recommend others to use Uber.
