This is the thread he is referring to http://localhost/forums/viewtopic.php?t=14427
In defense of the forum members I must say it is understandable that they would see them as strafers, the configuration of the parts (tee chamber with barrel comming out, air input on bottom of tee...) are very similar and your website was just recently made. Since the homemade strafer design is widely available and you make no indication of what the feed mechanism is, I don't think that was too wild of a conclusion.
The negative comments on your products, except the bondo one, were based on the information you presented on your website. It's good you plan on making a new video, that's a step in the right direction, but I think you need to work on your external design of the gun. I don't mean that as an insult, just constructive criticism.
You're not likely to find many sells here since this is very much a DIY community, but perhaps you could use this forum for feedback on your designs from other homemade BBMG builders.
