I hesitate to write a negative review on this product, since after all it was a *free* gift. However, I think it's important that people have an idea as to its quality so they can make an informed decision as to which gift they choose.

For those new to cock rings, they basically have two purposes: to help prolong an erection, and (for the ones with bullets) to provide extra stimulation via vibrations. The EdenFantasys vibrating ring failed on both fronts. I doubt the weak vibrations would satisfy even the complete beginner to toys. Seriously, it's that bad.

The Edenfantasys vibrating ring is made of TPR, which is a silicone blend. It's not pure silicone, but as far as I understand it is basically non-porous and body safe. This factor is one of the few redeeming features of the toy. I did not detect an odor at all from the material, which in my book is a good thing. There is some texture on the bullet part, but I didn't feel it at all during use.

Unlike some other cock rings, this one is most likely not large enough to fit around both the penis and the testicles. It should, however, fit most penises and dildos. My husband has slightly above-average girth and he was quite comfortable wearing it.

There are no fancy vibration modes here; just one setting, which is pretty weak at that. It is kind of hard to turn on/off when being worn, so be sure to turn it on before. The switch does not tend to turn off during use, which is nice. Too bad neither the vibrations nor the texture did anything for us.

This is supposed to be a "one time use" toy, but technically you can use it until the battery wears out. Our session was only roughly 10 minutes, and it still had some battery left, so we will be using it again. To clean it, I simply removed the bullet (I'm pretty sure it's not waterproof) and washed it with soap and warm water as I do with all my toys. It is currently stored in my toy box, not touching other silicone/TPR toys because I'm paranoid about ruining them.

The cock ring is packaged in a simple plastic package. I honestly don't remember if there were instructions printed on it or not, as I threw it away as soon as we opened it.

It's a shame that with so many great things going for it (body safe material, comfort, etc.) the cock ring is utterly useless. I have a *very* sensitive clitoris, to the point that vibrators often cause me discomfort, yet I could barely feel this one. Also, my husband, who has trouble orgasming too quickly and has had success with another cock ring, found this to be completely ineffective for him. My advice? Invest in a decent cock ring that you can replace the batteries for, preferably one with a ring for the balls. They are available on EF in the range of $10-$20, and of course you can use points if you like.
