Posh, Posh, What a Disapointment.This is a nice medium range cock ring, but I did not like the weak vibrations. I would recommend buying a different cock ring.
-Does not stretch much
The ring feels like soft rubber and does not feel uncomfortable even though I found it very hard to get on due to the lack of stretching. One thing you should also note is that this ring does not have this "drag" feeling where you feel it's dragging your skin, which I have experienced with other cock rings.
Now onto the bullet--it is made of hard plastic with an on/off push switch. It needs two watch batteries, which are included. Furthermore, one thing you should note is that this ring has very weak vibrations--the Edenfantasy's cock ring has stronger vibrations. The bullet lasts 15-30 minutes before you will need to replace the batteries. You can use this ring in the shower, but if you are planning on submerging this in the water, I would recommend taking out the bullet, as it does not state it is waterproof.
The ring has little nubs and grooves for added stimulation. Personally I did not feel the nubs on my penis and I doubt any lady would feel the weak vibrations of this product, and because you cannot fit this over your balls, you cannot use it to stimulate your testicles.
The bullet is about 1 inch long and can be replaced with a bigger bullet of your choosing. It is easy to push it out of the casing.
The bullet can be removed if you desire this. You could put the bullet inside a Fleshlight or sleeve if you have several or you can use this as a clitoral massager.
The bullet should be removed and cleaned by a wet towel with soap and then rinsed.
If you're new to cock rings, this is a nice starter cock ring. If you like strong vibrations, however, get something else. I have decided to only give 2 stars because of the weak vibrations and because it did not fit perfectly.
