The Smartballs Duo is Fun Factory's two-ball pelvic floor trainer. Inside sits a spherical weight that moves as your body moves, so your muscles respond to a shifting load rather than a static one. The tapered tip is shaped to make insertion straightforward.
Within the Smartball range, the Duo sits above the single-ball Uno. Fun Factory points beginners toward the Uno and positions the Duo for people who are ready for more, which makes the Duo the step-up option for those with some pelvic floor training behind them.
The Smartballs Duo is made for people who want to train their pelvic floor and already have a little experience with it. Because it uses two weighted balls rather than one, it fits users ready to move past the entry level and take on something more demanding.

FAQ
What people most often ask us about the Smartballs Duo.
Inside the Smartballs Duo sits a spherical weight that moves as your body moves. Rather than staying static, this shifting weight prompts your pelvic floor muscles to respond and work, turning everyday movement into training. You wear the two balls internally, and the tapered tip is shaped to make putting them in straightforward.
The two sit in the same Fun Factory range but target different levels. The Smartball Uno has a single ball and is aimed at people starting out with pelvic floor training. The Smartballs Duo has two balls and is built for those who are more advanced and ready for a more demanding workout.
It is not the version Fun Factory points beginners toward. The Duo carries two balls and is positioned for more advanced users, so it can feel like a lot if you have never trained your pelvic floor before. If you are just starting out, the single-ball Smartball Uno in the same range is the gentler entry point.
