Street Bees, anyone used them before?

A friend just suggested this beermoney site to me, says it's legit and they pay through Paypal, and usually pretty quick after you cash out as well. I'm wondering if anyone else has any experience with them, I cannot find a whole lot of information online about the site. I'm also curious if it's mobile only or if it works for desktop as well, I can't find a clear answer on that either.
