I'm trying the robot in a demo account, and it has been very successful for me. I don't have a MT4 account open, but I have made 13 pips in real money on one trade by manually submitting a trade in another account.
If you want to return it, don't return it through them. Go directly to click bank, and you'll get your money back.
As for Mark Larsen, I don't trust that he is an "Independent" although I may be wrong(He has a Forex Systems Reviews website). He claims to be independent, and they don't join any affiliate or referral program. However, if you put your cursor on the links on his site to robot systems that he has reviewed, with the exception of the FAP and Forex Killer, they all have his url followed by the name of the system. I may be wrong, but I believe that those are signs that they get credit for a referral. Please correct me if I'm wrong.
Also, I am on their mailing list. He has a partner named Ryan. When I get emails from Ryan, it has the same physical address:
Ryan
wilhelm greilstr 14
innsbruck
tirol 6020
Austria
as I get in an email from Andreas and Marcus, the founders of forex killer and faps, so once again, I may be wrong, but it appears that Larsen and FAPS are connected.
