@tmitch Hah- family jewels in a mouse trap! Hilarious!
I did have a moment of panic when I was testing out the original constriction ring and that sucker was not going to come off. Yikes.

Thanks for the advice on the blue rings-going to go down that route. I have a Vacurect pump, which is fantastic for the therapy part, but it's a nightmare if you're wanting to do the constriction ring thing. Their rings are unforgiving. But, the pump is great for the therapy approach.

FWIW: I did some studies referencing the benefit of using vibration as a way to wake up nerve sensation. I could probably hunt down those links.

Good luck with whatever devices you find. Let us know if you find any good ones. Hang loose! (especially with those blue rings)
