Interbank FX Credit and Debit cards?

Has anyone used the credit and/or debit cards at Interbank FX as a convenient way to quickly access your funds? I know that the cards are tied to a side account but I am wondering how simple it is to move funds from my trading account to my side account.

On the surface it sure looks a lot better than having to wait a week or two to get your mitts on your own money.

Hi mintjelly,
I am curious to know myself. I am in the process of opening up the bank account being interbank is my broker. So maybe someone here has already done so and will let all of us know if it's worth it or not. Seems to be really promising or at least I hope so....
