I've wanted to use it, and I probably will be in the near future.
Not a lot of people uses it or even have it, so don't expect to get a lot of payments through it.
You can't get chargebacked is what I've heard from people. You do know that in order to acquire funds in it, you'll have to buy it or get someone to send it to you. I'm sure that's one of the only ways. And there's usually a fee, Busta does it for a 3% fee.
