This is a one time use disposable vibrating cock ring. It can be used during sex or for masturbation purposes, whichever you choose. The ring is thin so I think it will work better on a man with a larger girth than a smaller one as it may slip. It is individually wrapped in a sterile container to make it perfect for travel so you can just toss it in your stuff and take it with you.

The Screaming O is made of TPR Silicone. It has bumps around the ring and ticklers on the vibrator attachment for added pleasure. The material is very stretchy to easily slide it onto the shaft of the penis. It is made of a food-grade silicone, is Latex-free, Phthalates-free, Hypo-allergenic and Non-porous. I found it to be very stimulating especially for the price. It had a slight smell as it came out of the package but nothing too overwhelming.

It is a ring that is 1 3/4" unstretched and will stretch to 2 1/2" in diameter. It has a tiny bullet attached by a sleeve that has ticklers on it. The bullet is approximately an inch long and the whole thing is a peach color. You activate it by sliding a button over and it runs for about 40 minutes according to the package. We only had it going about 25 but it lasted with the vibes steady for that time. The vibes are not super strong but they are strong enough, a medium vibe. The batteries are already in it and not replaceable as it is disposable. It is very quiet as well so discression is in your hands...so to speak.

I have mentioned before that my boyfriend is a truckdriver and I travel with him from time to time. This is how we used this. We took it with us on a trip. Seemed perfect because in the truck the only way to clean things is to wipe them down. It did not let us down. He is big in girth so it fit him perfectly, but because the band is thin it may not fit someone with a penis on the slimmer side as well as a thicker one. After using it we just tossed it in the trash and were done with it. For us it worked very well and I would definately recommend to someone who travels or is with different partners.
