The Smartballs Teneo duo are a set of revamped Ben-Wa balls, created by Fun Factory. This toy is the second generation of Smartballs from the same company, and provide all of the same benefits as the original with some key design changes. They are very body friendly and are designed to strengthen PC muscles while providing gentle stimulation.

The construction of this toy is very similar to the original Smartballs. Two individual balls connected by a small bridge, each ball houses a small circular weight which rolls around during normal daily movements, creating small tremors and slight vibrations. The vibrations cause the surrounding muscles to contract in an attempt to keep the balls in place, and these contractions exercise the pelvic floor muscles. The sensation tends to be very pleasing for many people. The key differences between the original Smartballs and these, is that the new ones are slightly larger (I believe) and the removal cord is designed to be attached to the toy more securely.

Another great thing about this toy is that it is extremely discreet. It is easily one of the most discreet toys on the market. The simple fact that they are small and are designed to be used internally during everyday activities requires them to be this way. This is the nature of the toy.

The Smartballs are also very very easy to clean. Being a completely sealed toy, the Smartballs are waterproof meaning they are dishwasher safe, are able to be boiled, and may even be cleaned with bleach.

Overall, I would recommend these quality balls to anyone looking to improve their sex life. The benefits these toys provide are invaluable. Strengthened pelvic muscles allow for more control during sexual activity, increase tightness, and (the best part, as I have experienced it with my girlfriend) improve the frequency and intensity of orgasms for the woman when she uses this toy regularly. This is an absolutely outstanding toy and I would recommend you buy it right now! Go!
