The Magnetic Power Ring Ridge Rider- by Cal Exotics
This cock ring measures 3 1/4" from top to bottom, and about 1 3/4" across. The inside of the ring itself is 1" in diameter, unstretched, and has a maximum stretched diameter of 2 1/4". It is composed of clear TPR/TPE (a 7 on the material safety scale), and has a small round magnet within the ring on each side. This product is hypo-allergenic, latex free and phthalates free. The material is somewhat rigid (not super floppy), but does have some give to it, for comfort.

The box for this cock ring is very obvious about what's inside, in NO way subtle. It's cardboard with a glossy finish, covered in photos of the Magnetic Power Ring Ridge Rider and info about what this particular cock ring does. When you order this product, it includes 1 cock ring, a 3-speed bullet, and 6 watch batteries (so you have an extra set for when the first set runs out). The type of batteries necessary are LR44 batteries, and the bullet takes 3 at a time.

The cock ring has one flat-faced bumper on top that holds the vibrating bullet for clitoral stimulation, and one bulbous bumper below for "triple contact". Both bumpers are ridged to make them even more effective in arousal. As I said before, the bullet has 3 power settings. The lowest setting is more of a gentle buzz, which would work relatively well for someone with highly sensitive genitals. The medium setting is about the average strength, similar to the power level of most "one speed" bullets. The high setting will rattle your bones. The bullet is made of a hard plastic, and would probably be a bit painful to use directly on the clitoris. The control for the bullet is an easy-to-use rubber button on one end of the bullet.

Now, for a few key notes:
-This ring is a bit on the small side, but you can work the material. If you want it to be a little more pliable or wider in general, put it around a larger bottle cap (vitamin water works well)
-The bullet CAN be switched out, if you have one you prefer over this one.
-This product is waterproof, so you can separate the ring and the bullet, then wash both in the bathroom sink after use.
-Water based lube would be best to use with this toy.
-I believe this cock ring is most effective if worn in the missionary or cowgirl positions. I'm sure that the folded deck chair position would work too, or any position that really opens that area up.

I think we're both in agreement that this is a pretty nice cock ring. It's heavy enough that there's no worry of it breaking/tearing when you're putting it on. The material is solid enough that it transfers vibration pretty well. The bullet is definitely powerful. The only bad thing I can really come up with is that it's a bit tight on well-endowed men.
