Many guys like me have been duped with cheaply made, ill researched, sub standard products.
However, the very first time I tried this constriction device, it enhanced my member, and it remained erect for some time. The ring/s are made of a material that gives, but retains an important element of resilience, and have a larger cross section. As their job is to temporarily halt the flow of blood in and out of the member, they work really well, used with the ball ring ✅, Thank you so much.
