Cock rings can be broken down into two major categories, rigid and stretchy. Two of the major purposes of cock rings are to make an erection easier to maintain and to prolong the period before ejaculation. Generally, rigid rings are better at accomplishing these purposes, but stretchy rings are easier to put on and take off, so guys are often more comfortable with them. Because stretchy rings are not as good at enhancing erections, they often are dressed up with additional features like one or more vibrators. This is why most rigid rings don't have vibrators while the majority of stretchy rings do.

The Screaming O's O Wow vibrating ring from the outset is a pretty normal entry into the realm of stretchy vibrating cock rings. It's certainly stretchy and it certainly vibrates. The vibrator is powered by three watch batteries and comes with two sets of batteries, so you shouldn't be left hanging, at least for a while. The vibrator is unusually powerful considering its size, so if you are looking for a little extra oomph from your bullet, this might be just the thing. All in all, it can definitely get the job done.

The O Wow is made of TPR silicone. This material is odorless and semi-porous. It is also great for being stretchy and resilient. The Screaming O even goes extra in the ring by providing two concentric rings connected by tabs around the course of the ring. This actually makes the ring a little harder to stretch and should ensure that it won't break. The front of the sleeve that holds the vibrator is textured with short ticklers intended to provide some stimulation for your partner. The softness of the material keeps them from being uncomfortable, but they aren't very noticeable either.

The vibrator is mounted horizontally which may not be the most ideal position for this kind of ring. Since the vibrator is medium size for a bullet, it does tend to get in the way in some positions. The size of the O Wow ring is pretty standard with an unstretched diameter just less than 2". It stretches to 2 1/2". This stretched diameter should be large enough for most guys.

The vibrator of the O Wow is a single speed push button activated bullet. It is surprisingly strong given that it is powered by only three watch batteries.

Taking care of TPR silicone is pretty basic. Just keep a few things in mind. Simply wash with soap and hot water or a toy cleaner. TPR silicone is semi-porous and cannot be sterilized, so sharing with the cock ring with other guys or multiple partners is not a good idea. Also, limit your lubricants to water based as others could cause material degradation. That about covers it.

The O Wow packaging follows the standard Screaming O formula. Clear, molded plastic attached to a cardboard backing meant for hanging. The backing has a picture of the top half of a woman in a tank top in the corner looking like she might be right in the throws of an "O". Other than that, it has basic information about product features.

Our experience with the O Wow was pretty good. It didn't line up real well with her clitoris and she didn't really notice the texture, but we could both definitely feel the vibrations. It was a little too stretchy to provide me with much erection enhancement, but it was definitely easy to get on and did not cause any discomfort to speak of. Taking it off afterward was easy as well, so the whole thing went over very well. Definitely one that we will keep around for possible repeat use.
