I have been using this card for a year now. When I first got this card, the transaction limit was very less(major drawback), due to which I used the card very less. Slowly my limit my increased and I started using this credit card.
I think the best part of this credit card is the cashback.
It will be auto-credited to the card account every month, so you will get adjusted against the bills. Basically AS GOOD AS CASH. I have used other credits cards(ICICI etc) which offer points on doing transaction but this CC gives you the cashback directly.
This card is useful for shopping on flipkart for 5% cashback, and regular shopping online/offline for 1.5% cashback. So if you are a frequent Flipkart user, you can try this card.
