Review: Fun Factory Smartballs Teneo Uno and Duo

Kegel Exercisers are wonderful things, they basically help you exercise the muscles of the pelvic floor without a lot of conscious effort on your part, you just need to remember to wear them.

Kegel exercises can be done in numerous ways with various different implements, not just balls, but the best well-known vaginal balls are Ben Wa Balls, basically a ball with another ball-shaped weight inside of it that wiggle around during wear and stimulate your pelvic floor muscles. They are best to be done every day for fastest results, just like any other kind of exercises.

The awesome thing about balls like these is that you don’t really have to do anything in order to be exercising your pelvic floor muscles except move. They are a wonderful way to spruce up even the most boring menial tasks! The weight in the center vibrates slightly as you move around giving you immediate stimulation and arousal while working your kegels.

In the short-term it will increase your arousal level and can be especially wonderful to use in a D/s setting. In the long-term the benefits of strengthening your pelvic floor are both practical as well as sexual. It improves urinary and bowel control and can also increase control over ejaculation for both males and females. Specifically for females they increase tightness of the vagina, can improve vaginal control, and can increase sexual arousal/desire. For males they can diminish premature ejaculation, encourage multiple orgasms (especially multiples without ejaculation), and result in a stronger erection.

Smartballs are not made for males, however, as they should never ever be used anally. For anal kegel exercisors check out the Aneros Peridise.

Original Smartballs vs. Smartballs Teneo Uno and Duo

Fun Factory took the basic design of Ben Wa Balls and came up with their Original Smartballs (image), two slightly oblong balls attached together with an easy removal cord which could be worn all day if you so choose.

The Smartballs Teneo line is basically Smartballs 2.0. Unlike the Original Fun Factory Smartballs the Teneo line of Smartballs are made of silicone, not Fun Factory‘s own creation of Elastomed. Also, instead of an oval-y shaped ball with indented slits around the sides in a different color like the original Smartballs the Teneo Uno and Duo have a bit more texture to their design, as you can see. They still have the inlayed slits, but have a ribbon of silicone moving around them for even more feeling when they’re up inside you.

Probably my favorite difference between Smartballs 1.0 and Teneo is the finger groove on the bottom of each ball which makes insertion much easier. Teneo was also improved by giving the wearer a choice between one ball or two, making it easier for beginners or those of us with shorter vaginal canals to work on our muscles using a more comfortable singular ball.

Finally, the retrieval cord on the Teneo line is also made of silicone and is the same color as the rest of the ball, unlike on the Smartballs 1.0 which was of an unknown material (not silicone), slightly tacky, and white regardless of the ball colors.

Smartballs vs. Other Vaginal Balls

Other than Fun Factory’s versions I have also tried the LELO Luna Beads and Ophoria K-Balls (review coming soon), both of which have balls which are closer to perfectly round than the ones found on any of the versions of Smartballs, but neither have a completely silicone cord or the extremely handy finger groove.

While the LELO Luna Beads do have the option between using one ball or two and also varying ball weights the balls are made of ABS plastic rather than silicone and the retrieval cord is made of a fiber which can get stiff after encountering fluid, which is highly annoying.

The Ophoria K-balls are made of silicone, but are much more similar to the Smartballs 1.0 than the Teneo line.

There are many other types of vaginal balls and other kegel exercisers out there as well, but these are the only ones I have experienced personally.

So… Are they worth it?

I think the Teneo Uno specifically is my favorite of all the vaginal balls I have encountered. The Duo is wonderful as well, but I haven’t made up my mind between it and the K-balls. Maybe by the time I review the K-balls I’ll have a better idea. They are definitely close to the top if not the very top, so I definitely recommend them.

A big thank you to Good Vibrations for providing me with Smartballs Teneo Kegel Sex Toy!
