PosTVac Mach Ring, A148, Size 6, Medium Inside Diameter 8.6mm (.340 inches)

nice rings, tried a good 30+ products of this kind since im type 1 diabetic so ED hit me at 20, venous leak, so these help A LOT takes me well above 100% full, worth a try if you suffer from that kind of thing works well both with and without a pumpGot a #5 ring small, worked very well, quite snug tho, not painful, just very tight, so got. The next size up, also tight but slightly less, might try the next one up (large) I'll update if I do.The extra thickness these ring provide helps a lot more than thinner ones that cut in too much, seem to be pretty well made and should last a good 30+ times if treated well

This is a complete joke! My husband is average size and he needs high tension but this #6 is ridiculous. You can't even fit a straw through it (no exaggeration) and there's not much stretch to it either as you might think. We couldn't even get it on the pump using the cone. If your an average American white guy in length and girth, I'm pretty sure that none of these will fit, even the largest ring if it's anything near the size of the #6. I'm not about to spend another $17 order the largest size only to find even the largest wont fit either. I couldn't even stand having it on my pinky finger, it was that tight. We have had a good laugh at this scam knowing these people are charging nearly $20 for a piece of rubber that can only be used on a skinny straw to keep it from falling underneath the lid of a cup. The main reason I'm leaving this review is because one is left with no recourse when the find out how truly tiny the hole is on this thing. For $17, you should be able to at least get a larger size replacement or a pack as an option since they offer very little in the way of size. I'll definitely not be ordering any of the Rejoyn products after this. The other guy who says these wouldn't fit a Pekingese is spot on. Thanks for the $17 piece of trash. What else do you do with it? Even the guy with a micro penis would die laughing at the size of this thing.

I purchase this ring and got well satisfied with the elasticity and compression that it gives to the penis when in use.The number 6 that I bought is very stretchy to load to a penis pump but goes back to the original size when removed to the cylinder.I also bought a number 7 which is also very easy to use and offers a comfortable pressure to the penis.I recommend if you, like me, suffer from ED

Works ok it is just hard to get it off the ver

I just reviewed the tension ring #5. These are good quality and not just silicone or rubber toy bands. These actually work! They don't have the kind of give you find in most of the products available. I wish the provider made their sizing a little more understandable. As I understand it, this item, the #5 is the most constricting of the Erec-Tech rings. It and the #6 work for me, which I can't say for a lot of the 'rings' out there!

No information on the rings bore dia. unstretched. This is vital to have before fitting.I found it impossible to apply on me.I overcame the problem by fitting to my wife's vibrator and leaving it there for a few days whereupon it was stretched sufficiently to fit safely. This can be a dangerous product to use and remove if not well lubricated .It is important that dimensions of the rings bore is shown.

Used one time and it split in a section, will look elsewhere next time.

This is the first time I have used these products. I was pleased with the quick response. So far the products have been satisfactory. During the ordering it would have been helpful if more accurate sizing information could have been provided. Items are a bit pricey to do much trial and error. Overall I am satisfied with my order and will probably place additional orders in the future.
