This was a great way to introduce my boyfriend to cock rings, and to vibrations in general. It is inexpensive (or free in our case). It's made from TPR which has a safety rating of 6. I prefer regular silicone, but at least it's not jelly. Since it's made of a silicone-based rubber compound it should only be used with water-based lubricants. It is easier to slide on with a little bit of lube. When you take it out of the package rinse it off with soap and water or toy cleaner. If you plan on using it again, clean it after use also. It is safe to use in conjunction with condoms. Since it only has a material safety rating of 6, it should not be shared with anyone that you don't share bodily fluids with. It is hypoallergenic, latex free and phthalates free.

It's considered a single use cock ring. The batteries are not replaceable. You can expect it to last an average of 20 minutes. It turns on with a little slide switch that can be hard to get hold of. The switch may inadvertently get turned off during use and is difficult to fuss with in the heat of the moment. There is only one setting of vibrations which are fairly moderate. I was pleasantly surprised that it's not that weak. It is slippery and I suggest being careful that it doesn't end up inadvertently sliding up the shaft and into the vagina during thrusting.

It can be used on a packer, a penis, or even used as a handheld clit vibe. Some cock rings are intended to trap blood flow into the penis to help maintain an erection. I'm not sure if this one is tight enough for the purpose. It could also be slipped onto a vibrator or dildo to add vibrations. It does have some nubs and texture around the bullet, but it did not do a great job of stimulating my clit during intercourse.

We used this a couple of different ways. My boyfriend slipped it onto the shaft of his hardpacker before we had sex to stimulate my clit. We also turned it around to face him. I could feel the vibrations both ways. With the silicone packer I could feel the vibrations through the whole shaft. The rubber packer did not carry the vibrations as strongly as the silicone one.

Using this vibrating ring did make us realize we would like one with two bullets instead. It was a great way for my boyfriend to experiment with vibration since it's not a female oriented product. He had always equated vibrational toys with vibrators aimed at females. After telling him that vibrations can be enjoyable to men also, a cock ring seemed to be the obvious choice to use, to show him.

Since this is essentially disposable, I really don't like it. It would not be my first choice as a free gift. If it was the only free gift option, I would still take it and set it aside to put in a blog giveaway pack.
