Vibration works if applied this way
I was also curious about this device and several years ago, attempted to duplicate it with 2 egg vibrators. It works. I place one lengthwise on the frenulum and one horizontally along the top of the glans just above the Corona. I use eggs with a dial up in intensity, rather than buttons with different speeds and multifunctional, ie different pulse patterns. I originally took the spring out of a large plastic clamp and used electrical tape to secure one to each jaw. I would lightly close it on to my penis so the eggs hit the correct spots. Immediately I started getting harder and it contracted my BC muscle. I found that by doing this in small doses, turning it it on until my BC muscle contracted completely, then turning it off while my penis engorged, I have and election within 30 seconds and, if I keep it there, I will ejaculate within another 30 secs. To a minute. Recently I decided to try a device on amazon that is just a silicone cup that fits over the head and has two eggs on opposite sides. The pictures show it with eggs on the right and left side rather than the top and frenulum. Of course I tried it both ways but it worked best my way. It still didn’t feel as good as my original though so I modified it by cutting one sleeve that held the bullet vertically so it could it horizontally. Voila. I can put this puppy on and be erect hands free for the most part. Then I will use it to edge and also I believe it’s working my BC muscle as I can now harden it all the way up through my penis and it is rock hard when I do so. I have moderate ED and take 5mg daily Cialis and this gets me so hard it’s ridiculous. I may actually do a video review of this sometime. Likely would have to post it on xtube or something but I think it is a secret gem. I also think it goes hand in hand with PE. It exercises, stimulates and maximizes the amount of blood going into the chambers so how can that be bad lol.
