There are cock rings and there are cock rings. Or if you like “penis rings” of course, but whatever you call them they are all different. This particular model is of a reasonable circumference that means you don’t feel you’re being garrotted if you have a large girth and manages to incorporate a relatively large and powerful bullet very effectively.

Let me explain.

The Jopen Ego G3 cock ring is a USB charged, silicone cock ring. The silicone used in its construction is soft and finished with a satin-matt surface that gives it a quality feel. Charging in three hours or less the Lithium ion battery provides reliable power to a vibrating mechanism that delivers thrumming, powerful stimulation to you and your partner.

Other features include a travel lock and the fact that it’s fully waterproof.

The size of the opening on the Jopen Ego really attracted me to this particular cock ring. I don’t like to be held too tight by a penis ring, either it has to be very flexible, or have a large internal diameter to begin with to appeal to me. The Jopen E3 has both, the perfect combination.

Here’s how the Ego E3 Cock Ring works.

You turn it on by pressing the clicky switch at the apex of the largest of the five segments that surround its vibrating bullet. I choose my words carefully here because the switch is nice and positive, you can tell you’ve pressed it because of the tactile and clearly audible click it makes. Discreet push-buttons are all very clever but especially when sex and lubricant is involved a positive action and feedback from controls is in my opinion essential. It rather detracts from the passionate moment if you find yourself fumbling with the controls on a sex toy.

When you’ve turned the bullet vibe on a light under the switch illuminates. The constant glow from this illuminates your love making, you certainly don’t need it to tell you that the cock ring is vibrating as even at its lowest setting the vibrations are rather powerful. Pressing and holding the button increases the power of the vibrations, the indicator light flashing faster as you do so until at top speed the light is constant. Whatever sped you choose when the button is released the light goes back to constant again. While a steady light while you’re screwing in the dark is rather kinky and illuminates your naughtiness in a very pleasing way I’m really glad the light is constant once you’ve set the speed – otherwise you’d feel like you were in a very freaky disco.

You can turn off the cock ring by pressing the button once. How do you reduce the power of vibrations? You can’t. The problem with a single button is that there are only so many functions you can cram onto it – on, off and increase is really all you need. Jopen could have added other buttons but then you’re back to a more complicated setup and distractions.

There is one final feature that the control button provides. Press it three times in succession and your cock ring is locked so it will not come on accidentally when being transported. Three times again and it unlocks ready to use. This works most of the time, though unlocking the cock ring was, I found, sometimes hit and miss. Not the end of the world.

When it comes to using the E3 Cock ring I was really impressed. As you’ll have gathered I can’t wear small/tight cock rings so with its reasonably wide opening coupled with nice soft but strong high grade silicone this one was unusually comfortable. Because of my girth it was quite tight but not the uncomfortable vein-bursting pressure that often stops me from being able to review these sex toys.

We first tried the ring missionary with the bullet above my penis and immediately realised this is a comfortable and very powerful unit. Despite the size of the vibrating section it wasn’t uncomfortable pressed between us. Far from it, the smooth curves didn’t dig in and the power of the bullet rocked us both as soon as we began to, er, enjoy ourselves.

When we switched to doggy style and I rotated the ring around the base of my penis we found the stimulation even better for us both. We ground against one another for quite a while just enjoying the stimulation!

In conclusion I have to say that I can find little negative to say about this vibrating cock ring, the occasionally temperamental travel lock perhaps it’s only flaw. I like the USB charging, it’s big enough for me but will fit most guys because the ring is nice and stretchy. The power of the vibrator is terrific and can genuinely be enjoyed by both partners without the weird gymnastics sometimes required with less powerful cock rings of inferior design. The combination of materials, shape and sheer strength of vibration means that like me you’ll be keeping this cock ring close to hand and using it often.
