Is Migros Bank any good?

I know Migros Bank has locations all over Switzerland and I have heard that Migros Bank customers can also make transactions at Migros supermarkets. That would be very practical for me (I live next door to a Migros). But before I bite the bait, I would love to get some first-hand reports from customers or ex-customers. Is Migros Bank any good as far as costs, services and customer service go?

Migros Bank information and products

Migros Bank has a lot to recommend it, in my opinion: branches all over Switzerland; cash withdrawals at any Migros supermarket with your debit card; consistently low interest on personal loans; transparent mortgage interest rates; integration with the Migros Cumulus rewards program; P2P mobile money transfers (MobilePay P2P); good cash services. Plus, it's backed by a tangible asset (the Migros retail group).

The rounding-based savings solution which rounds up transactions to the nearest X amount of francs and automatically transfers the difference to a savings account is a very useful feature for people who have a hard time saving.
