Let me try to help you out since no one else did.

I don't know the vendor, so cannot comment on his business, but I know this and this applies not just to the vendor in question but all others as well:

1) two days of watching may not be enough to form a correct opinion about someone's trading abilities unless he has been awfully bad; say, no winners at all,
2) if the vendor does not have some kind of trading record (at least a few weeks of trades recorded in real time), then I would not bother with a trading room; that's because it's a sign that he is fishing for easily impressionable people that he is hoping to get lucky to convince he has something to offer,
3) never rely on the opinion of people who post on trading forums unless you know that they have done business with the vendor; too many people on trading forums have their own agendas, and unless you do know their agendas, you cannot be sure how valid or useful their opinion is.

Hope this helps. Ultimately, you are on your own, and the sooner you accept it, the better. Good luck.
