Had mixed experience on this account. This is a rotating rewards card. As such I would supplement it with another rewards card(s). They don't report what category your purchases are so there is no way to tell which merchants qualified for the extra rewards or to verify you got what you should. Customer service has been responsive on this issue, but not always helpful. Rewards were easy enough to redeem.
They jacked up my minimum payment and apr during the crunch. Luckily did not touch my credit limit.
One shining light in customer service was when they took care of a mistake they made to my rewards balance years ago. My balance some how went from 0 to negative without any activity made by me. I wanted it fixed before I started making charges and they fixed without hesitation. Small deal, but having it go smoothly did a lot to make my day.
This is Similar to the Citi Dividend and the Discover More Card. The Citi card makes you recieve rewards as checks. Customer service at Citi is similar but slightly better than Chase. Citi did not jack up rates during the crunch. Although has done so in the past. Was able to later get those rates back down. Discover had one bad customer service many years ago and haven't looked back until recently. It isn't always accepted so it needs another card more than this Chase. Overall, decent rewards card, good online feature set, poor interest rate, and big bank policies and customer service.
