I received the Bon4Micro yesterday, it looks very well made but it has a serious design flaw. Like all very small guys, and that's what its made for, I have had issues finding a fit. This one is tiny but the flaw is I can just pull out the back. There is nothing to keep it on. The site says "The new BON4Micro offers the less endowed, men with a flaccid penis between 1.5” and 2.5”," Well, I fall in that range and it does not work. Do not spend any money on this one. The online chat on the site blamed me for not fitting. Even though I fall in the range. 219 bucks gone. Live and learn and avoid this one.
