PosTVac Mach Ring, A141, Size 5 Small Inside Diameter 6.5 mm (.25 inches)

I liked everything about the tension rings. They fit over the penis pump and when pumping causes an erection the stretchy ring is slid off the pump and onto the penis. When the pump is removed the rings hold the penis snugly to maintain your erection. There is no discomfort whatsoever, it is a rather enjoyable feeling. It also enables you to enjoy entended periods of love making. You can contact me if you want any further information on this excellent product. [email protected] Roy G Sydney Australia

Great product Ring is strong and durable Made thick Great material Holds it shape And stays in place

Material does not disintigrate when stretched following repeated use,

Wish I had gotten the next size up. A little pricy, can't return once package is open.

This works very well for my fiancé.

Easy to use very confrontable.

Works as you would want it to. However it didn't last through 5 uses. Way too expensive for almost 5 uses

Tight as Fu@k. It tore a little when I stretched it onto the Pos-T-Vac. think I might need to order another just in case.
