The Magnetic Power Ring Double is a stretchy cock ring designed to be worn on the penis during sex. It slows the flow of blood from the penis, helping you to stay hard for a little longer after finishing.

The ring is made of hypo-allergenic, phthalates-free TPR. It is also latex-free. TPR is normally compatible with both water and silicone based lubricants, but the included insert states that you should "always use a water based lubricant with this product for maximum pleasure." TPR is porous and cannot be sterilized, so you should not use this toy with multiple partners.

The Magnetic Power Ring did have a slight smell when I first opened it, but after only two uses the smell was no longer noticeable. The material is very stretchy, and will accommodate most penises easily. If your (or your partner's) penis is very thick, however, I would probably suggest finding something else unless you like your cock rings to be really tight.

As indicated by the name, the Magnetic Power Ring Double consists of two separate rings which are connected by four small "connectors". The larger ring, worn at the base of the penis, is 5/8" from the base. The smaller ring is 3/8" and the "connectors" are 3/8", making this cock ring a total of 1 3/8" long. If your penis is on the shorter side of the spectrum, you might find the overall length annoying. The inside diameter of the rings is 1" normally, and can be stretched to about 3" with only a little effort. I wouldn't recommend stretching it much farther for fear of breaking it.

The unique double ring design of this cock ring provides two "choke points" to prevent the blood from leaving your penis. On each of the two rings there are two, nickel-free 5/8" spherical magnets. If you look down on the ring from above, the magnets on one ring would be located at the 12 and 6 o'clock position, and the magnets on the other ring would be located at the 3 and 9 o'clock positions.

What purpose do the magnets serve? Honestly, I'm not sure. According to the Cal Exotics website, "The power of magnets has long been recorded as a natural healing technique in many different civilizations throughout history." Unfortunately, the magnets didn't make any noticeable difference to me.

To clean the Magnetic Power Ring, just wash it with soap and warm water. Dust can get stuck to it pretty easily, so I suggest allowing it to air dry. I keep this product in its original packaging so that it won't collect dust.

The packaging for this product was pretty minimal. It was a simple clamshell case with a single paper insert. There aren't any erotic pictures or raunchy words on the clamshell, but it is clear, so the cock ring can be seen, meaning it is not discreet at all.

The insert has a picture of the cock ring on the back, along with instructions for use. We are reminded to wash before and after use, and that a cock ring should not be worn for more than 30 minutes at a time.

When I first got this product, I was really surprised at how big it is. I was worried that since it was so long, it would stop me from being able to penetrate my wife deeply. I was also a little worried that the magnets constantly hitting her vaginal opening might be uncomfortable. Luckily, this was never an issue. She said that she didn't even notice it.

One problem that I did have was putting it on. Since the ring is so long, it was surprisingly difficult to get my penis into it. I found that applying lube to the penis and the inside of the ring was necessary to get it on comfortably. The ring is definitely not sticky, but if you have a lot of hair down there, be ready for some pulling.

The ring was pretty tight on my penis, but it never got uncomfortable. It fulfilled it's main purpose, which was to keep me hard after ejaculation. I was able to go for a few extra minutes after finishing, and there was never any discomfort. Aside from a few hairs getting pulled, the ring was easy to remove.
