Review: Good quality. This size is very tight - Came fast and as expected. Good quality. This size is very tight.
Review: Way to small! No exchanges, replacement or refund options. - 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.

### ⭐⭐⭐⭐⭐ quite nice for my needs
*by J***E on December 31, 2018*

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 pump Got 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
