Fun Factory's Smartballs are not the typical Ben Wa Balls. Unlike most Ben Wa Balls, Smartballs are two connected balls with smaller balls the rotate on the inside as you walk or perform normal daily activities. The Smart Balls are 4 and a half inches long and about an inch and three eighths in diameter at their largest point.

The Fun Factory packaging is cute. It's always tan and red with the product you're receiving drawn on the front and has a window to see the product you bought. They also come with a packet of sample lube from the fun factory. The sample I received was their Bodyfuild, which is a silicone based lube. Because the Balls are elastomer they can easily use the silicone lube without any issue.

Smartballs are completely discreet as they hardly make noise outside the body and no noise when they're in. When mine were delivered, however, the package was rattling from the movement of the balls. Be aware that there really isn't a way to stop them from moving when picked up. They also require no batteries because they are kinetically powered. As long as you're moving so are they. Insertion wasn't a problem for me. They stay in very well as long as you haven't worn them too long. The only problem I've had with the balls falling out was after a full 8 hours of wearing them, so if your muscles are tired they might have a tendency to come out.

When moving, the balls vibrate enough to stimulate both your muscles and you. The vibrating can be fairly inconsistent between different uses. Depending on the angle they get inserted at or the way they bend in you it can either be a totally constant vibration while you're walking or moving vigorously too to long pauses between. Either way is equally exciting and sometimes surprising. The only thing concerns me about this toy is the fact that the string looks like a rubber band. I don't believe it will break and if it does, it's not like it's going anywhere but to be safe I wouldn't recommend trying to see how far it will stretch. This too is NOT meant for anal use. It doesn't have a flared base and could easily get lost inside you.

As it's an elastomer toy it's very easy to clean. For day to day use they can easily be cleaned with warm water and antibacterial soap. If you're looking to share these make sure you sterilize them by boiling them in water. Since this is an elastomer toy you can use both silicone and water based lubes with it.

Using something like the Smart Balls will exercise your pelvic floor muscles. It's definitely lead to better sex and orgasms for me personally. Pelvic floor muscles also are the muscles that control your bladder; if you have need to improve bladder control, it's a good product to use. It's a product I would highly recommend for teasing and to work on your pelvic floor muscles. It self however will not give you orgasms, so if you're looking for a toy to masturbate this would not be the toy to get. Smart Balls vibrations are based on movement, so they could add some pleasure if used while masturbating, but only if you're moving fairly vigorously. If you're looking for something to tease you and improve your sex life however this is the toy to get.

Still using, still loving. These balls have shown no wear or tear whatsoever, and they're still fun to wear. I definitely feel an improvement in my pelvic floor muscles. I've had no problem cleaning them, and I definitely still recommend them to anyone who wants a good and easy way to improve their sex life.
