Pos T Vac Mach 1 Ultimate Round Erection Rings From Erecaidpumps

I purchased the sample kit and these rings were my favorite of those included. I have found that if I rinse the rings after use, dry thoroughly and store in the original plastic bag (or plastic sandwich bag) it slows the deterioration of the silicone and they last much longer. I'm also careful not to nick the ring when inserting on the cylinder. Very comfortable

They are an excellent purchase. Long lasting and do the job well

I can wear this the longest

These work great to maintain erection - strong enough that vigorous thrusting does not force out any volume. Only problem is that after about 4 uses the ring belong to split, then with a few more uses it breaks.Gets expensive having to keep using a new ring.

This ring is very durable and strong. Excellent.

Really like the thicker ring, seems to stop venous leakage much better than regular ring.

83 works for me.

The rings supplied with the erecaid pump 16 years ago were not tight enough to sustain an erection for me. Good to have sex again at 79.

I have found this to be more comfortable than the rings provided with the original kit. The ring is thicker and a softer plastic. It has greater elasticity than the originals. The first one developed a thin spot after more than a year and I was afraid that it would break, so I ordered new.
