Personally I haven't converted well on this product but it was on a site that overall didn't convert anything very well
It depends very much on how you market it - I used to promote it with PPC and converted 1 in 50 hops. I stopped because clicks were too expensive for me at the time. I might try it again but with all the competition I doubt it will convert like that these days.
I don't understand why its not converting for you guys. I ran a simple craigslist campaign on it back when craigslist was a kick-ass marketing spot last year and made a 3 conversions per 100 replies. Thats pretty good if you ask me. I put no more than 2 hours into the whole thing. Like the guy above said its all in how you market it. If you can't market something effectively you'll do poorly. Its got high gravity and a pretty good salesletter don't don't know what went wrong for you guys.
