MASTER SERIES Ring Master Custom Ball Stretcher Kit for Men, Set of 5 UltraStretchy Silicone Rings, Adjustable Tension Design for Personalized Fit, Comfortable Wear

Works great THOUGH over time they develop a weakness and DO BREAK which can be somewhat PAINFUL!

All five rings have already begun to split. Two has broken completely. I have not even had the rings for a week. If these were any more expensive I would call this robbery. The molding design of these things are the issue. Most have split in the same section of the ring where the silicone was poured into the molds. Even at the low price, don't waste your time.

Rings work fine, but parachute is a bit tough to work with so be patient

These are so tight as to be dangerous. I put them on and immediately started turning purple. I do not recommend.

They are nice,but they split. Have 2 sets. First set 2 had split after 1 use. Second set 1 already split, .

Arrived on time. Exactly what I wanted. Will buy again.

My husband has used these for a couple years now and of all of the ones he has tired he likes these the best. They are easy to put on and off, you can decide the tension based on how many you put on so you can choose different tension easily and often. Unfortunately they are very crappy quality and break often so I have to replace them regularly and that gets more expensive than it should. Because he really likes them I keep ordering them but are they a good value for the money? Absolutely not. They need to do better on the quality. If they want to charge $20 for rubber rings then make them last longer. When I first started ordering these from Adam and Eve they were $5.99. That is where the price should stay if they don’t want to improve quality

It broke on first use. They refuse to make it right
