Deceiving size Review by Leonardo
Product Rating
I ordered this product and it was the biggest mistake I made online. I chose the 12.5mm and the true size of the product is so minuscule that it is simply impossible to use it as a constriction penis ring. If used in this way, it would shut down all blood vessels feeding the penis shaft so tight, it would soon produce pain around the genitalia and would turn our modesty a blue/purple colour due to the lack of blood and oxygen supply. This product design is flawed and it raises questions of ethics and honesty. Constriction of this tight calibre cannot be beneficial for the human body in any way. It will ultimately produce pain.

Dear Leonardo
Thank you for the review, I am sorry this size was not suitable, the rings are designed to be constriction so tight at the base, but obviously not so tight as to be uncomfortable, just to do the job. There are 2 larger sizes than this one, please let me know if you would like to try one of these for a more comfortable fit.

Unobtrusive Review by Stuart P
Product Rating
Comfortable to wear and easy on/off with the loops as I can't grip, but I can get my little finger through. Unlike the previous reviewer I wanted a good seal and firm constriction as many other rings like this fail to secure an erection fully because of the looseness. Unobtrusive while lovemaking.

Product Questions

What do the sizes, 8mm 25mm etc mean. Do they mean the width of the erect penis or the width before stretching. How does one assess the size needed? My penis is about 40 mm wide erect but of course the ring would need to be less than that otherwise there would be no pressure available for it to work to maintain an erection
