Interesting design, but it looks like poop. Literally. I would not spend $100 on it personally. Forgive my being blunt, I just figured I would let you know, as a consumer, my opinion on it. For example, if it was smoothed and made to look more realistic, then that would be great. Or if it had some sort of aesthetically pleasing shape, then that would be fine too. As it is now, it looks like, well, you know.
I agree with Sir I'm afraid; however I do love the concept of the removable balls - complete genius! For me though they do look a little comedic, I hate to sound horrible but my first thought was of those fake dangly balls in Jackass à la Bad Grandpa.
The other thing that hits me is the obvious turd shape (I think it's the 'bubbly' texture), to me a toys appearance is almost as important as the feeling it provides, a well sculpted dildo is indeed a thing of beauty! I also have concerns about all the various nooks and crannies...the way the balls are 'affixed' looks too rough and unfinished. Do they slip even with the 'drag' that silicone affords?
Honestly for the price I would expect a more polished product, as mentioned earlier...I think if you smoothed it out and give it more defined glans/discernible penis shape then you'd be on to a winner.
As negative as I seem, I think you have some great ideas and huge kudos to you for making it happen!
