This Super Enjoyable vibrating ring can be used by men, couples, or can be placed on dildos. Advanced users won't get a lot out of this toy as the vibrations aren't extremely strong, and the TPR silicone stretches too much to be an effective cock ring. It allows blood flow and will not keep the penis full of blood and erect.
The vibrator is quiet and can be worn in public for the vibrating thrill. However, it is not waterproof. This can be worn by the male with either the vibrator resting on top of the shaft against the pubic bone and sending the vibrations onto the clitoris during some sex positions, or the rings could be placed in an upside down manner during solo sessions. It could also be worn during penetration if the partner doesn't like or want the vibrations. This would vibrate against the perineum.

TPR silicone rates on Eden's material safety scale 6 out of 10. Since it is silicone, this means water based lubes only. It does have some nubs and fingers for clitoral stimulation and is extremely stretchy. I was able to carefully get both rings to stretch around a beer can and the un-stretched diameter is 1 5/8". It should be washed with a toy cleaner or warm water and anti-bacterial soap before and after use. It should not be shared among partners due to the porous material and the inability to completely sterilize the ring. The bullet can be removed during cleaning, but should be placed in the holder upon use as the vibrations are at least 95% of why the toy has a use. The batteries are not replaceable.

The design is simple-two stretchy rings with the vibrator bullet on top. It has an easy on/off switch that has one vibration setting- on (or off). It will fit all but the pencil thin penis. The toy will stretch if stretched slowly, but will break at a given point or if stretched too fast.

We have used this as an addition to regular sex, stimulating both the male and female, but this is more of a male toy as 100 percent of the time the male will feel the stimulation, and the vibrations weren't felt much by the female. The Super Enjoyable Vibrating ring isn't really super enjoyable, but the vibrations are a nice touch against my penis, and I have worn it for hours on end. The hearing aid sized batteries haven't given out yet. When the batteries die there will not be any use for the toy as they can't be replaced, and I will look for another vibrating ring.
