FUN FACTORY Smartball UNO Kegel Ball Trainer

If you're after an uncomplicated way to start pelvic‑floor training, the SMARTBALL UNO is the sort of item I'd hand you across the counter. Inside the soft, body‑safe silicone shell sits a small weighted ball that shifts with every step, offering passive stimulation to the pelvic muscles without you having to do a lot of conscious contracting. At 45 g it’s purposely light — comfortable to wear for short sessions while you go about daily activities.

How to use it

Lubricate the tapered tip with a water-based lubricant and insert the ball until it sits comfortably. Start with short sessions — around 10–15 minutes — and increase time as your pelvic-floor muscles feel stronger. You can wear it while walking or doing light daily tasks; the internal weight moves with you to provide subtle stimulation and encourage muscle engagement. Available in Purple and Black.

Cleaning and care

Because it’s made from body-safe silicone and rated IPX7, you can rinse it under warm water and wash with a mild, toy-safe soap or a specialised toy cleaner. IPX7 means it tolerates immersion (commonly up to 1 metre for short periods), so washing is straightforward. Dry thoroughly before storing and avoid silicone-based lubricants, which can degrade the surface over time. The SMARTBALL UNO is backed by a 25-year warranty from the manufacturer for long-term reliability.

Who it's for: people starting pelvic-floor training who want a light, easy-to-insert weighted ball to wear during daily life. Who it's not for: if you want an intense, gym-style kegel workout or multiple vibration modes, look at heavier or motorised trainers instead.

For beginners wanting a gentle, lightweight kegel trainer that’s easy to insert and wear during daily activities.
