This is a entry level vibrating cock ring. Ours came free with a order from another site (had to order something eden did not carry, sorry).

This ring measures in at about 1 1/2 inch diameter unstretched. I am not sure what its maxed diameter would be, I did not try to stretch it to its max. The site says it is 2 1/2 inches. My diameter is about 1 5/8 inches, and this ring stayed on without any problems. If you are any smaller, you might have problems keeping it on. Of-course if you are using a condom, that will add to the overall diameter of your penis.

This ring is made from TPR silicone. Making it pretty flexible. I would use water based lube with it. Of course this is up to you. This cock ring is considered a one time use item, so if silicone lube did damage it; it would not matter at all. We used ours twice before the batteries died.

Cleaning and storage are not an issue, because as stated above this is a one time use item. It comes sealed in a "condom" type wrapper. That can be stored anywhere. You open it up when you are ready to use. After use you take it off and throw it away. No cleaning of storage needed at that point.

They state that the batteries last about 15 minutes. We got about 30 minutes out of ours. The controls are simple on the vibrator. Just one switch. On or off, simple and easy. I have not seen any replacement bullets that fit in this cock ring. I would like to see a way to replace the batteries, so you can keep it around for awhile longer. But until they change this, single use only. So when its dead, its dead.

Over all, this is a decent product. I would not pay $5.99 for it. But it came with another toy, so we used it. If you could pick up a box of them (like condoms) for $2 a piece, I would be all over it. It added a nice change to the normal routine.

When I put it on, I was worried about it pulling my hair. I have seen alot of reviews for rubber and silicone cock rings, and that has been a big problem with all of them. But I had no problems with getting my hair tugged out. I do not know if it was because of the material, or because I keep things clean and trimmed.

The vibrations were also on the weak side of things. It was just enough to give me vibrations, but could not be felt well by her. She could only feel the vibrations when the bullet was up against her clit. I see they now have a double bullet cock ring out, that one might have taking care of this problem.

There is not much of a follow up review I can write about this one. They are a one time use item. If you are looking to try a vibrating cock ring, it might be a wise investment to give this one a try first, just to see if it was enjoyable before going out and purchasing a more expensive ring. I would not relay on this for more then one session. It can be expensive stocking up on these rings.
