Smartballs Teneo duo - vaginal balls by Fun Factory - review by Crystalline Dragon

Just Meh

I would not buy these again, as they were quite anticlimactic. I would look for a set that didn't have a layer of silicone over another layer. It's too much, and you lose vibrations.
Good to build up those Kegels
Easy to Clean
Well Made
No orgasmic activity here
Too large for those with great Kegels
Barely felt a vibration
Rating by reviewer:
extremely useful review


These are great for building up those Kegel muscles that do not require you to sit there and focus on it. These will do it for you.

They are supposed to be worn so that you can discreetly stimulate yourself while building up pelvic floor muscles. Again, great for the latter, but do not produce any vibrating sensations.

Material / Texture

The silicone is always my first choice for any toy, at it is just so much easier to clean! However, there is just entire too much material to freely feel the weighted balls moving around.
    • No odor
    • Not porous at all
    • Rigid

Design / Shape / Size

I purchased these specifically for the weighted balls, and the vibrations. As I enjoy edging without having to stop what I am doing to accomplish my task. I have two sets, and this is by far the larger one.

I really do not need to improve my muscle tone, as it's really good. So these are actually a bit too big/annoying for me.


I have a cheaper/smaller pair from a local toy store, and I do not have to work at all to feel the weighted balls. These, I have to walk like Jessica Rabbit in order to feel any vibrations. It may be because it's a tight fit for me with these.

I also must use lots of coconut oil to help get these in. I was once told I could stretch myself out, so the larger toys wouldn't be a problem. Nope, not going to happen for a toy.

Care and Maintenance

Again, silicone is the best. You can sterilize these, clean them with toy cleaner, hot/soapy water, or throw them in boiling water. It says dishwasher safe. Nope, I have a small child who would inevitably find it.
    • Easy to clean
    • Easy to store


Cute/discreet packaging. I wind up replacing the boxes with silk bags.
    • Discreet looking packaging

Personal comments

For all its beauty, and durability, it is not my first choice in "Kegel Builders". For me, I need nothing more than 1 1/4". This one is just a little too much to be anything more than a chore.


If I am playing with G spot vibe, and have these in, the vibrations from that vibrator makes it worth pulling them out. Otherwise, they stay in their bag.

    I agree with you. The items with weighted balls are a novel idea, but don't perform.

    Sorry these did not perform as wanted and that they were too big.
