Honestly I was pretty content with the fees involved when I used it for Euros a couple years back. Afaik the fees aren't trivial but at least they're not steep (unlike e.g., using PayPal to do the same thing) - I didn't really feel robbed but it'll depend on what your expectations are!
I feel like no matter what you do someone is going to rob you blind when using foreign ATMs and foreign currency transfers.
