Customer Reviews
Easy Festgeldkonto setup
I opened a Festgeldkonto with Big Bank DE last week and the process was so straightforward! The interest rate for new customers was really good, better than I expected. I'm already planning to tell my family about them.
Consistent service over time
I've had a Tagesgeldkonto with Big Bank DE for a while now, and just opened another Festgeldkonto. The application for the new account was quick, just like my first one, which took maybe 3 days to get fully set up last year. They've always been reliable, and their rates stay competitive. It's why I keep coming back for my savings.
