I’d also be interested in helping to beta test new products. I’ll be sure to go over the strengths and weaknesses that I see, and I’ll do my best to offer suggestions and ideas on how to improve the designs. I also might be able to help do that, as I am familiar with designing 3d objects. (I created a line of penis rings that I have designed, if you are interested in having a look at examples of my skills. Just let me know, and I’ll send the info.)
The reason that I mention the penis rings is that I use them along with my Stealth(s), to help maintain the anti-turtling capabilities, and to keep the penis somewhat engorged to help keep everything in place without retraction.
Anyhoo, have fun all 🙂
