This is a good toy for beginners. Due to it being stretchy rubber it is good for all size penis's. I used it with my husband and we had a lot of fun, it being waterproof was fantastic because we love to have sex in the shower. It hit my clit in just the right way and the vibrations felt wonderful. I was skeptical at first but grew to love this ring. I would suggest that you maybe use a small amount of lube to get it on the penis due to the rubber sticking. With stretchable rings, the rubbery material can sometimes stick to hair and pull it, particularly when you’re putting on or taking off your ring. To avoid having your pubes yanked, make sure your genitals are well-lubricated. Dry your hands before putting on the ring. You don’t want to lose your grip and have it snap your penis like a rubber band. Try rotating the cock ring so that the vibrator is in a new position. This can provide greater stimulation of the clit, which can feel wonderfully intense. Remember that while vibrating cock rings are typically designed with a male/female couple in mind, gay and lesbian couples can just as easily enjoy the pleasures these rings have to offer. For gay men, what would stimulate a clitoris will buzz the scrotum just as well. And for lesbian couples, you can double your pleasure by adding a vibrating cock ring to your favorite dildo and turning it into a dual-action vibe.

Cover w/ a condom to keep clean, especially if you’re planning on sharing.
It's very stretchy, has a rubber smell, no bad taste and is easy to clean and keep clean.
The stretchy TPR material lets this ring accommodate any size man and feels comfortable against the skin. Both vibrating bullets are removable for clean-up. Waterproof. Phthalate Free.

A vibe on top of the ring and at the bottom. The top vibe helps turn his erection into a vibrator and the soft, textured nubs stimulate her clitoris. The second vibe below the cock ring swings with his motion and teases his testicles.

It vibrates at a mid to low level. It did it for me but might not be strong enough for others.

You should always wash after use because it gets covered in fluids. I keep it in a plastic bag in our door. Easy to clean just soap and water.

User instruction were not included but it kind of explains itself.

I thought it was fun and something nice to spice things up.

Well we mostly use it in the shower and it works well there. Though it is good in the bedroom.
