I am from kolkata. I have been using this cab services from the past one year or so. The best thing in uber is the security as they have well authenticated and verified drivers.
The drivers drive safe as well. I stay in the outskirts of kolkata, still I am never denied by uber. Few of the other cab services have denied me of past. The cost of travelling is also cheaper than tbe other cab services and traditional taxi’s. I would suggest people to use uber because of the security it provides
