This cock ring should fit just about any size male. It can be used with or without the vibrating bullet that comes with it. Other size bullets can also be used in this toy. Since it is so small and the material is soft and flexible, one could choose to wear just the cock or the ball ring and let the other sort of hang off to the side. It can be used for couples or solo play. The Invisible Companion could be used by anyone anywhere on the sexpertise spectrum, but is probably best for beginners or those somewhere in the middle. The rings could be used in the water, but the bullet can't and needs to be kept dry.

The Invisible Companion is made of TPR, which is hypoallergenic, nontoxic and phthalate free. The package does state what material(s) the cock/ball ring or bullet is made from; I had to go to the Eden Fantasys website to obtain this information. Eden Fantasys puts this toy at a 6 on their Material Safety scale.

The cock and ball rings are both quite stretchy and thin and should fit any penis and ball size, except maybe the man with the world's largest penis, which he claims is 13.5" long and 8" in circumference! This product has little to no odor and is very smooth when used with lubricant. There are no painful seams or hard objects to worry about. There are a bunch of little nubs around the front side of the ball ring that rub on the balls. My husband said he did not notice these at all. There are also some nubs on the clit tickler. The clit tickler registered a big fat 0 on my radar.

We liked that the bullet was between the cock and ball rings. This seemed to provide greater vibrations to his penis and balls, which was in turn enjoyable for me. The bullet is easily removed or inserted from the hole designed in the toy between the two rings. It looks small, but has quite a bit of stretch so a larger or smaller bullet could also be used with this toy. We did have trouble with the bullet slipping out once things got lubed up, so I imagine a smaller bullet would not be a good choice.




The rings are quite stretchy and are easy to put on and take off. My husband really liked the fact that the rings were thin and narrow and made out of minimal material. This was a plus as they a) did not move and roll a lot, which kept his hair from being pinched and pulled, and b) gave him greater feeling and penetration depth without having a bulky material in the way. This would definitely fit the average male, and even those who are above or below average.

The cock and balls rings fit my husband perfectly and stayed in place. No rolling, rubbing or hair pinching. They fit snugly yet were not too tight. He did say the ball ring got a little uncomfortable at the very end of a 30 minute session, but the product packaging says not to wear longer than 30 minutes and he was right at the limit. My husband does not have difficulty keeping an erection, so I can't comment on how well this toy may help with that. The Invisible Companion did help him to last longer, which is enjoyable for both of us, and a main reason we use these types of toys.

We also both enjoyed the vibrations from the bullet. You have to be a little careful with very hard thrusting as I felt the bullet grind up against me a few times. Most of the time I just felt the vibrations though, and not the actual bullet hitting me. It only has one speed, but is pretty decent at around a 3 on the vroom scale. You twist the wheel at the end of the bullet to turn it on. I did like that you can continue to turn the wheel quite a ways after the bullet is on. For us this, helped keep the bullet on during use. Some other toys are easily turned off by movement or friction. It takes three watch batteries, which will get costly, I imagine. The product did come with six total watch batteries though, so that is pretty awesome.

Our only complaint about this toy is that the bullet slips out during use. It's happened to us every time. It fits snugly at first, but once things get lubed up, pop goes the bullet!

The Invisible Companion is made out of TPR (Thermoplastic rubber), a silicone based rubber compound. TPR is less porous than cyberskin but more porous than silicone so it is recommended that you wash TPR toys before and after each use to prevent the spread of bacteria. TPR can be cleaned with mild soap and water or antibacterial sex toy cleaners. This material cannot be sterilized by boiling. I usually let my toys air dry after washing. The Invisible Companion is small at approximately 2 1/2" (bullet) by 3" (length of cock/ball rings), the material has little to no odor, and it is easy to clean and doesn't seem to pick up much lint, so we just store it in the bedside drawer with our other toys. You need to use only water based lubricants with this toy.

The packaging is not discreet. It opens easily by simply pulling the two plastic pieces apart. There is no information on the packaging about the materials the toy is made of.

We've used several different vibrating cock rings, all made of stretchy material, and this has become our new favorite. We really like that fact that it takes up little room in our toy drawer and on him. We both can feel each other better without a bulky ring getting in the way. I love how this cock and ball ring keeps him hard longer; more time for me to enjoy him! I also like how the ball ring wrangles those little suckers in and pushes them forward making it easier for me to feel them during sex, oral, a hand job, or pretty much anyway. They are there, front and center, wonderfully displayed.

The bullet has a habit of slipping out of this toy. I still really like it, even without the bullet, but I do wish it would stay in better.
