Anyone using Denizen?

I established an account, linked it to a U.S. checking acct, received the free $100 sign-on bonus, and will use the debit card for the first time when traveling in Europe in two months. I figure I'll mainly use it to withdraw cash when needed, and thereby reduce the amount of cash that I bring from home. Will be interesting to compare exchange rate with that of my other bank cards and commercial exchanges.
