I've used their service twice just to test it. Deposits clear in a few days, but month-long delays and endless excuses/hollow promises from support staff for withdrawal of fiat $ or even small amounts of BTC (under $50).
Note. I did get my funds out of them in the end.
Avoid.
I was using them up until around 6 months ago when I couldn't stand their incompetence and bumbling stuff-ups any longer. Fortunately though I've never had the appalling experiences of direct loss people are now experiencing.
Here's a BCT thread detailing what's been happening over the past few months. It's a disaster for people who have fiat or BTC there.
Don't even think of using them.
