I Dont know why ICICI has got only two star.It is one of the best private sector bank in india.
The best thing I like about Icici Bank are their services are too fast and with their debit cards yes debit card not credit card you can shop globally.I bet you no other bank debit card will provide you to do international shopping but with icici debit card you can shop international.
One more thing about icici bank is that it offer its whole service online.I think it is one of the beat private sector bank in india and you get best interest rate on fixed deposit or any other insurance policies.
