We chose this cock ring because it has two bullets and two loops. I also liked that it is made from TPR silicone instead of jelly. The other reason we chose this one is because the batteries are replaceable. The versatility is great but may be an overkill for beginners.

Each bullet can be used alone or with the ring. The large ring can be put around the shaft of a penis or hard packer allowing the lower ring to dangle the smaller vibe. You could attempt to put the smaller ring around the testicles with caution. We broke the lower ring this way.

You could place this ring on a toy, like a hardpacker, or penis.

It has soft textured nubs everywhere! The TPR silicone parts are soft and stretchy. The bullets are a hard plastic but the sleeves they go into are what touches both partners. It does have a slight odor to it if you sniff it, but the scent isn't noticeable during use. I suggest using water-based lube to make it easier to put on and help avoid pulling hair. The material is slightly porous. It is not as bad as jelly, but not as good as pure silicone.

The bullets are removable and interchangeable. You can choose which bullet you want on each end or choose to leave one or both out. The bottom ring is much smaller and does not stretch as well as the upper ring. We actually ended up breaking the lower ring. I think we should of switched it around and placed the smaller ring around the shaft of the hard packer and used the larger ring to go around the balls.

The larger bullet is powerful for a bullet vibe and has an O-ring to keep water out. The smaller bullet is made of a cheaper plastic and does not have a seal. The larger bullet works well as a handheld bullet vibe. It has a separate piece of soft TPR with nubs that is like a sleeve to go over it. If you use it as a handheld bullet vibe it feels better with that on because the plastic casing is hard.

Do not use silicone-based lube. Do not boil. Wash with soap and water or toy cleaner. Remove batteries before washing or storing. The smaller bullet is not waterproof. It is porous, so do not share with anyone that you don't already share bodily fluids with. Rinse or clean before each use, as it does attract lint and hair.

Inside the package are two LR130 watch size batteries. These go in the small bullet at the bottom of the lower ring. Unscrew the cap, remove the small piece of paper from the battery compartment and put those two batteries into that bullet. It takes a steady hand to screw the cap back on straight.

The larger bullet comes with LR44 batteries already in it. We couldn't initially get it to work properly, and we then discovered that battery case also had a piece of paper that had to be removed. The larger bullet does have a diagram to show which direction to place the batteries in. The larger bullet is easier to handle and replace the cap on.
