Nothing much more then standard... so basically nothing worth mentioning.
As it goes with all of them... proceed with extreme caution.
Edit:
Looking at good and bad things, following could be mentioned thought:
They started around June 2006 and have been paying 32% for the lower plans to 50% monthly for the bigger players. They went private in December if I'm not completely mistaken. They have however been a tad crazy (for my taste) with changing plans after that.
As far as I know know no real DD has been made, no proof of real business.... although I read somewhere that people actually went and looked at one of their prospects. Some claim to have met them in person and there's a RL meeting coming up. They do use the (infamous) bank of america tower virtual office/service in hong kong.
(I've been in since December and I'm in profit)
