This is a simple cockring and bullet vibrator unit for those curious to try out combined-use toys - those designed for shared-use by couples. Not as expensive as some, so this is a decent entry point for beginners.

Covering the O Yeah! is an ice blue stretchy sheath of what seems to be elastomer. There's no smell out of the package, and the material is resilient, very stretchy, and clean of seams. It comes armed inside the sheath with a translucent blue plastic bullet vibe similar in shape and size to those bullets used by Tantus.

The sheath material is covered with seven rows of smallish nubs about the thickness of a good cocktail toothpick. They are flexible, soft, and only a few millimeters high. The cockring is a about 1/2 thick, but is pierced in three places to allow easier stretching over the member.

The material was noticeable and not restrictive. but not that engaging. There was some impatience with the nubs after a few minutes of dedicated use. ('Pokey', was the word used.)

This product was designed to be 'perfect for cowgirls who really want the ride of their life'. That meant moving the more common horizontal placement of most vibrating cockrings to a vertical shaft about 35 degrees out from the cockring. The result is a vibrator unit about the thickness and length of a man's thumb that should lie atop the clit and nestle within the labia when worn on the penis so the unit points to the man's belly-button.

The cockring is about 1/2 inch thick but is pierced in three places for easier stretching over the member. The join to the bullet cover from the ring is strong, and there is a bead on the join with a circle of smaller nubs, probably intended for clitoral stimulation. The cockring was easy enough to get on an erect penis, and could also be stretched to sit at the base of the shaft and behind the balls if desired.

There's no difficulty when stretching the ring onto an erect penis, and removal is as easy, and applies to inserting and removing the bullet into the sheath as well. Things stay well in place until no longer required.

The heart of the O Yeah! is the 'Super Powered Removable Vibrating Bullet'. Compared to similar bullets, the vibrations were underwhelming and the buzz pitch high, irritating and obtrusive. (My partner said ‘sounds like we're at a Model Airplane club'.)

The bullet is wireless and waterproof (sealed with a rubber o-ring, and the single speed on/off switch covered in a rubber button), but not one I'd recommend, which limits its use outside of the sheath to households with fervent ipod devotees, or without children or roommates. The watch batteries (included) are good for about 80 minutes and can be replaced, and the on/off toggle is not easily hit accidentally during use.

Clean-up is easy, using soap and water or anti-bacterial lotions. Keeping the elastomer sheath free of lint and hair might be a problem, but that can be washed off before use. Storage in a small plastic bag would help keep it clean.

The bullet vibe can be removed and washed in the same way. Let the sheath and the bullet air dry before re-inserting...or wait until just before using to do so, so water doesn't collect inside the elastomer cover.

The package for this unit is not much bigger than the toy itself. The card is full of promotional promises such as 'Keep ‘Em Screaming!', but does a good job of outlining the reasoning behind the toy's various features and location.

Of course it contains two of the more common notes: "This product is sold as a novelty only" and "Made in China".

The vibrations from the O Yeah! were, well, understated. They don't travel very well into the penis when the ring is worn at the base of the shaft. This changed for the better when the cockring was stretched and placed (traditionally) both behind the balls and at the base of the penis. For doggy or rear entry positions the 'thumb' was turned 180 degrees, and the result was some pleasant sensations being felt through the balls, and if the 'thumb' is not in good contact with your partner's clit and labia, a free hand can help snug it up to fix that.

In 'cowgirl' or female on-top positions the grinding into the nubs and the weak vibrations lead rather quickly to a point where the irritation outweigh the modest stimulation.
