Pos T Vac Mach 1 Ultimate Round Erection Rings From Erecaidpumps

works perfectly

Currently this is the only ring I recommend for use with a vacuum pump. I use the tightest fit ring to keep erection longer. After a few uses it has a tendency to lose strength and I may lose some of my erection. I found out that using two worn out rings together works great until they eventually break from repeated use. Trust me I get a lot of use from these life saviors. My love life wouldn't be complete without being able to make love on demand and with short notice. I use the pump for 5-10 minutes to ensure that my erection is very hard and erect then carefully slide rings off pump while maintaining its vacuum. However, the rings are painful to take off after twenty or thirty minutes when penis is still hard and erect. Makes for great sex though and the prep vacuum time is not a problem because I use that time for foreplay. Note, some girls are not used to the large girth which it produces for me and can be painful for them. Lubrication and starting slowly solves that problem.

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.
