My girlfriend has never been too excited to have a conversation about kegel exercises. She has not been able to figure out exactly how to do them or what muscle to use. When I first purchased her the Smart Balls by Fun Factory, I was a bit hesitant of her reaction, however, the thought of her using them was a huge turn on so I couldn't pass them up.

The day I received the package in the mail, I brought it home, and opened it with my girlfriend. Fun Factory has packaged their Smart Balls in a small, yet informative box. They also include a sample of their lube, Body Fluid. As we removed the smart balls from their packaging, we were surprised by their texture. Smart balls are made out of the hypoallergenic material elastomed, which neither of us have ever dealt with before, although I do own a couple penis sleeves made of it's sister material, elastomer. The hypoallergenic properties of the elastomed are good for women with sensitive skin and because it is nonporous the balls are resistant to bacteria. As such, they may be completely sterilized by the usual methods, i.e. boiling them, washing on the top rack of a dishwasher, or using a 10% bleach solution. However, if you don't plan on sharing them then simple warm water and soap should do just fine. Also, and what is a major plus for this product that sets it apart from other similar ones is the fact that the retrieval string is also coated in the elastomed material, unlike many of it's competitors which use regular string that can hold and spread bacteria.

Now, how exactly do these work? Well, there is a small marble-like ball within each of the spheres of the Smart Balls that rolls around inside, and when inserted in the vagina cause the Smart Balls to give a vibrating effect, which in turn is suppose to make the vagina contract. When used over a period of time this should strengthen the PC muscle and make female orgasm more pleasurable. However, this hasn't really been the case with my girlfriend, and instead we are enjoying another great aspect of the balls.

As mentioned, the Smart Balls have a slight vibration effect to them, and not only do they help with strengthening your PC muscle they can, for lack of any better words, make a woman horny! My girlfriend found the subtle rolling around of the marbles inside their spheres and the vibrations they caused very arousing, and it wouldn't take long after having them inserted that she was in the mood to have some one on one quality time.

Overall I would say that both her and I are very happy with our purchase and would highly recommend the Smart Balls to anyone interested in a way to strengthen their PC muscle for better orgasm or to help with libido.
