This is an average, beginner credit card. I have redeemed $50 in Apple Store gift cards at this time, which they email to you. The website has many more options than the app.
As other users mentioned: Use this primarily for Apple purchases. You can call right before you buy a new Apple product to get interest-free financing over and over again with whatever new product you want.
Customer Service was United States based - they lowered my interest rate to 16% (lowest is 13.99) after 8 months. I barely paid interest but still called to get them to lower it, took about 5 minutes.
Keep it around for your yearly Apple stuff and that's about it.
