I'll start off right away and say: I have NOT used this with my beau. He's not the toy-type, but I'm trying to convince him.

Anyway, I was unsure about this, but I got it as a free gift with an order so I figured it wouldn't hurt to try it out. See what it did, how it felt, so on and so forth. I love the way the jelly of the ring feels, it's so very flexible, soft and feels very nice. It definitely feels like it could be very comfortable on a penis, especially one that's erect. I used it on my Ocean Bliss glass dildo, about 3/4 of the way down. It was okay if I turned the dildo downward, such that it pointed towards the bed and the bullet part of the ring was pressed firmly against my clitoris. However, even inserting to the point that the ring touched and even slightly pressed inside of my vaginal opening, I couldn't feel a difference between having the ring turned on, and having it turned off. The only difference it seemed to make was in making a noise in the room, that is unless pressed and angled as afore mentioned.

The ring is a very elastic, jelly-like material. No smell that I could detect, though my nose HAS admittedly been a bit sniffly lately so it is entirely plausible I wouldn't have smelled a more faint odor, were it present. As far as elasticity, if you/your partner's girth is on the greater edge of the spectrum, it might be a snug fit. For the most part, it was a very comfortable stretch, that I can't see cutting any circulation off at all. The downside, the gel material really REALLY likes hair. It doesn't pull on hair, but it likes to pick it up if it's loose.

The shape is fantastic. The design could use some work. The material isn't a very good conductor of kinetic energy, so the vibrations of the bullet that is included are hardly felt; if felt at all. Around the ring itself, maybe with a stronger bullet, they could be felt. I really just think the material itself is the wrong choice for carrying the vibration energy. It is not adjustable really, other than stretching to fit the penile girth, however it's very easy to put on and take off. If angled right, I could see it working very well with partners, as a more downward angle lets the bullet touch the clitoris. Straight insertion, not so much.
