Pos T Vac Mach 1 Ultimate Round Erection Rings From Erecaidpumps

Is very soft and feels good, but even thought the most restrictive still allows for bleed back . Would work better if material was not so soft. But it is very comfortable.

A great product

Great quality Works best for me using 2

Very satisfied

.

I was using a competitor’s pump and ring system prior to buying POS T VAC. Incredible results!. The competitors rings lasted once. They ripped and didn’t hold an erection even with the smallest ring. The diameter of the tube on the POS T Vac is 2” and the competitors is 2-3/8”. It doesn’t sound like much, but thats a whopping 38% more circumference. 6.283” for the PTV cylinders to have the rings stretch to. The competitors is a huge 10.0002” circumference. This new pump will pay for itself with the savings in rings. And they slide off easier too! With these rings I now have enough time for foreplay with the wife and time for both of us to get orgasms.

So far so good

These are AMAZING you guys rock! Thanks

It Works! It does the job and is more comfortable, it is thicker than the others, so only one works as well and better than two of other bands.
