Fun Factory Smartballs Duo Kegel Exerciser

The Fun Factory Smartballs Duo is a two-ball kegel exerciser for people who've already got the hang of single kegel balls and want their muscles to work a little harder. Each silicone-covered ball has a weight inside that rolls as you move, and with two of them the movement is stronger and harder to ignore. This listing is the white and grape colourway, with a flexible retrieval loop at the end for pulling them out.

How this kegel exerciser works

You don't squeeze or switch anything on. Once the balls are in, everyday movement such as walking, climbing stairs or tidying up makes the inner weights swing and tap against the inside of each ball. Your pelvic floor reacts to that small, constant motion by tightening to hold them in place, which is the whole point of a kegel trainer. Fun Factory describes it as for regular, short sessions rather than wearing all day, and notes that the effect fades if you stop training.

Should you start with the Duo or the Uno?

Fun Factory pitches the Duo at people who've already trained with the single Smartball Uno or who already have a fairly strong pelvic floor. Two balls give more weight and more movement, so if you've never used kegel balls before and the Duo keeps slipping, start with the Uno and come back to it. If the Uno now feels like it does nothing, the Duo is the next step.

Putting them in and taking them out

Wash them, then add a little water-based lube to the first ball. Lie back or stand with one foot raised and slide them in like a tampon, tapered end first, until the first ball sits just past the entrance and the retrieval loop stays outside. Get up and move around: if they slide out, you may need the Uno for a while. To remove, relax and pull gently on the loop. Start with 15 minutes and build up from there.

What it feels like

Most people notice a soft rolling or tapping deep inside when they walk or climb stairs, and very little when they sit still. For some it's mildly arousing, for others it simply feels like a reminder to hold on. It isn't built as a vibrator or a dildo, so don't expect sexual stimulation from it; think of it as a workout you can do while getting on with your day.

When to skip it

Check with your doctor or a pelvic floor physiotherapist before using any kegel balls if you're pregnant, have recently given birth or had pelvic surgery. Leave them out if you're sore or irritated, and take them out straight away if they cause cramping or pain.

Care

The outer shell is silicone, with plastic inside. Use water-based lube only, which is what Fun Factory specifies. Wash with warm water and mild soap before and after use, dry completely, and store them in a pouch or their box, away from dust and lint. They're waterproof, but they're for vaginal use only, never anal.
