Smartballs Teneo duo - exerciser for vaginal muscles by Fun Factory - review by KateQ

Great alone or with a partner in crime

Highly recommended! The high quality materials make them far superior to cheaper Ben Wa balls (which often use hygienically questionable materials like string and may be too small for beginners). A very fun way to perform kegel exercises.

-The sensation from the balls may not be as intense as you'd like

useful review


One fantastic thing about this toy is that it's suitable for use anytime anywhere — from spicing up chores to acting as a shared secret on a night out! It's size, shape and material can make it a tad difficult to insert at first though — I recommend warming up and/or using lube before insertion.

Material / Texture

The balls themselves are very firm and coated in silicone. Although this is great for hygienic regions (far superior in quality than any with string or a cheap metallic coating) it means you may want to add a little extra lube before you try slipping them in.
    • Flexible
    • No odor
    • Not porous at all

Design / Shape / Size

So pretty! There are just two things I would tweak about this toy. First, the "connector" is a bit stiff for my liking, making it difficult to position the balls inside of you (and making them a bit finicky if you have a low-sitting cervix). Secondly, the balls inside can rattle a bit loud for my liking (although it's probably fair to say that I'm excessively paranoid about anyone hearing!) and don't make as intense of a sensation as I would like.
    • Beginner
    • Discreet look/design
    • Partner play


These are the first set of Ben Wa balls that I've ever owned and I love them! Although there are a few tweaks I'd like to make, it's hard not to love this very fun way to get your kegels on. You can use them virtually anywhere, the materials are high quality and they're fun to wear (as well as insert and remove)!
    • Comfortable
    • Discreet sound

Care and Maintenance

The silicone makes this toy very easy to keep clean — a wash in soap and water will do it. Be sure not to use it with silicone-based lubes (as it will degrade the silicone).
    • Easy to clean
    • Easy to store


Good modern packaging with instructions. Won't make you feel sleazy!

    You want a more intense sensation but quieter? Those two things might be in opposition to one another. Congratulations on your first review and welcome to EF.

    Thanks for the review. I would have liked if this has a grab. Is this why you mentionned it is better to add more lube?
