Product Description

Made by Fun Factory, the Smartballs Duo Kegel Balls are a perfect toy to help strengthen the kegel muscles on the pelvic floor, help increase blood flow to the vaginal area, help with incontinence, and help prepare for and heal after childbirth. However, one of the primary goals of the Smartballs Duo is to provide stronger orgasms.

The Smartballs Duo features an easy-in mold that allows easier insertion. These balls have weights inside that are encased in silky-smooth silicone. The weights roll inside the Smartballs, providing an internal workout for your muscle and strengthening your pelvic floor. However, this model is suitable for more advanced users and should be used after the Smart ball Uno.

The Smartballs Duo Kegel Balls are made from body-safe silicone and are compatible with water-based lubes. These should be used in short, regular periods, increasing sensitivity for improved sensation during sex for best results. The Kegel balls need to be cleaned before and after every use with warm soapy water or toy-cleaning liquids.

Features of the Fun Factory Smartballs Duo

  • Weighted Balls: The Smartballs Duo have weighted balls in a tapered silicone cradle.
  • Tapered Silicone Cradle: The silicone cradle is tapered for easy insertion and comfortable wearing.
  • Kinetic Movements: The Smartballs Duo works with you; the movements of your body shift the balls inside, giving your muscles the workout they need to become stronger.
  • Body-Safe Silicone and ABS: The Smartballs Duo’s cradle is made from silicone, while the balls are made from ABS plastic, both body-safe materials.
  • Waterproof Use: The Smartballs Duo are waterproof and submersible for easy cleaning.
  • 2-Year Warranty: The Smartballs Duo, like the other Fun Factory toys, are covered by a 2-Year manufacturer’s warranty.

What Makes The Smartballs Duo Unique?

The Smartballs Duo are kinetically operated as they move with you. The cradle and balls are tapered, with an ergonomic shape easy to insert and wear comfortably. The Smartballs Duo have small, weighted, movable balls inside the bigger balls, then put in the tapered silicone cradle attached to a retrieval cord. The Smartballs Duo come with the Fun Factory 2-Year Warranty.

How To Use The Smartballs Duo

Add a little bit of quality water-based lube to the silicone Smartballs cradle. Slowly insert the toy inside the vagina, positioning it comfortably and leaving the retrieval cord outside. The Smartballs Duo can be worn to strengthen your Kegel muscles, increase blood flow in the pelvic area, help the body recover from childbirth, aid arousal, and strengthen orgasms. The Smartballs Duo should be worn for up to 30 minutes at a time.

They work for me

I haven’t used this type of toy till now and decided to get it as a gag gift for my GF. As far as how it worked it was great, my girlfriend did say after a while it became difficult to keep them in but that can be fixed in multiple ways.

Great balls

Fits nicely I have strong muscles so doesn't fall out. No smell, easy to clean and maintain. Overall, a happy buyer.
