I was skeptical in the initial days about my manhattan platinum card. But once I got, it was a very pleasurable experience from the past year. The best part is the 5% cashback on groceries! I have got more than 5000 for the same. Apart from that, one more good thing is 5x rewards, I have made more than 10k points and always there will be discounts on flipkart and ebay. Overall, a very good card with awesome customer care. Of ourse, one or 2 times, they took time but all other cases, they were very helpful.
Try it but make sure u utilise all the features .
