When you look at any internet marketing product, you have to look at it as face value. We are all marketers and in a sense "sales people". When a new product is launched, it has to be badged as "the next best thing" or it won't draw any attention. New (or old) products will work for 10% of the crowd and won't work for the other 90. It all depends on that stage of a marketer you are. It may work for the noob, but is a waste of time and money for the experienced. I will say that many returns/refunds are due in part to "not understanding the product itself". It is far easier to request a refund than it is learning.
I personally, within my year of internet marketing, have not come across a legitimate scam. The beauty of it all is...If it doesn't work? You get a refund.
I always use my own judgment. Is this $27 product really going to get my $45K a month starting in 2 hours from now all on autopilot? No, probably not. Is there a good chance that I will learn something new from this product? Yes, a very good chance. I base all refund decisions on whether or not the knowledge gained was worth the asking price.
