This offering from Hustler Toys is a pair of cock rings that can be used to provide extra stimulation for a partner and your shaft/testicles. They will provide restriction of blood flow out of the penis; this can give you more girth and prolong ejaculation.

The Black ring is tighter for more restriction, while the white one will give you less restriction. Both come with color coordinated mini vibes that fit inside the rings. In this way you will not be "Poked" by the hard plastic but instead you will have a nice cushion of the material to provide comfort.

Both of rings are made from soft, smooth and shiny Hypoallergenic, Phthalates and Latex free TPR. They do have quite a bit of drag but they do not grab hair during use, they are dust magnets so a quick rinse before use is advisable. There is a slight smell but only when held close to your nose, there is no noticeable taste.

TPR is porous and cannot be sanitized, so no sharing. You do get two rings, so this should not really be a problem.

The plastic vibes are about an inch long and half an inch in diameter. There is a chamber in the top of the ring that thy fit in snugly. These are a bit of a pain to get in fully but they do not work their way out during use. I would not recommend using lube to make insertion easier for fear of lube entering the vibe's switch. In needed you can use a pinch of cornstarch.

The vibes take L736 button cell batteries. There is a sticker on the side of the housing to show you how to place them in the vibe. There is also a sticker to show you how to line up the cap when putting it back on.

The first thing you will notice is the design of these rings. The "Tails" do not point towards you partner, rather they point to the side. So while the tail will not provide you partner with a "tickler" it will put the vibe directly against the clitoris. This is perfect for grinding in the missionary or cowgirl positions. If you place the ring around just the shaft and point the tail down it will also work for doggie style positions.

The black ring in noticeably more tighter when wearing than the white. This allows you to provide the restriction you prefer. They can also be use at the same time; one around the shaft and one around just the testicles. Talk about a two-fer, eh?

Both rings have an un-stretched diameter of about 7/8", but they will stretch to fit around a pop can if needed. So there should be no problem fitting the largest penis or around both the shaft and testicles. The vibe portion extends an 1 1/2" above the ring, plenty to reach most clitorises.

Yin Wang's vibes provide some nice stimulation for their size. They may not be strong enough for some users but certainly will help. The switch to turn them on/off is easy to access once installed in the ring. Unfortunately it can be jostled off during use. To solve this problem, make sure the switch is oriented side to side, on your shaft, not front to back.

Care for your rings is very easy; wash with soap and water or use your favorite toy cleaner. Make sure to remove the vibes first as they are not even splash proof. Allow to dry completely before storing.

Silicone or water based lubes will work wonderfully with these rings but not oil based. Oil based lubes will degrade the material. It is recommended to use some care when applying the lube, care should be used to not get any in the vibes.

You can store them in their packaging or in a plastic bag. You could just throw them in a drawer but they are dust magnets. If you do not mind giving them a quick rinse before use, that would work fine.

As you can see the rings come in a small zip top bag. The front is clear to let you see the rings displayed to look like the Yin Yang. There is the name and company logo. On the back you will find some info on the rings and on Hustler Toys. Inside, behind the rings, is a silver stiff piece of paper. On the back there is a folded piece of paper that shows how to install the batteries and provides some warranty information.

One note of interest is Hustler provides a calorie burning guide on all their toys. These ring will burn 42 Cals/Hr with use. Burning calories and enjoying pleasure is a good thing!

I am a bit torn between liking these rings and hating them; Yin Yang.

First the likes. As a C-ring they both do their job well, they provide restriction and the wife likes the vibes during use. I can feel the vibes through the TPR around my shaft pretty good. Used by hand I found that the tail is nice used as a tickler. Around nipples, testicles and my urethra they are quite stimulating, although the tail tickled the wife to much. It was very fun to use both at the same time, one around my shaft and one just around my testicles.

Hates. I would have preferred the tails to point towards my wife to provide more stimulation for her clit. The batteries did not last more than on session and until I figured out how to orient the switch, it kept turning off. I also found the vibes to be somewhat cheap in their construction; the cap does not stay on the best and the contacts are flimsy and needed adjustment. The switch needs a more positive lock when turned on/off, this would negate the need to position it a certain way.

So overall, they are a good deal as far as getting two different rings each with their own vibes. They provide good restriction and nice vibes to the wife. They fail in battery life and vibe construction. Thus, they get a three star rating from me.
