Zopa credit card, anyone have one? Thoughts?

Just wondered if anyone out there has got themselves a Zopa credit card? If so, how does it stack up against the rest of the crowd? Is the App any good?

I recall the only positive of this card was the fee-free foreign spending - they use the standard Visa rate without any loading. But then when I was digging around I found my existing Virgin Money credit cards are already fee-free in Euro, Swedish Kroner and Romanian Lei. Unfortunately I don’t expect to the travelling too far afield this year.
