Smartballs Teneo uno - exerciser for vaginal muscles by Fun Factory - review by MrSinister

Teneo Uno: No Es Bueno (at least for us)

For some, the Teneo Uno can be too big, too small, too bumpy, too rough or too mild. If you are looking for a ben wa ball under 5" diameter and with mild stimulation, you will think this product is JUUUST RIIIGHT!
Can improve overall vaginal health.
Not for everybody.
Not easy to clean/maintain.
Low stimulation.
Rating by reviewer:
useful review


The Teneo Uno Smartballs from Fun Factory are designed to improve overall vaginal health, by causing your pelvic muscles to involuntarily contract while the product is being used.

The product is inserted like a tampon and worn while doing everyday activities. According to the instruction manual, this product will, over time:

- Strengthen your pelvic floor muscles
- Help make childbirth easier
- Repair vaginal tissue post-childbirth
- and help make a stronger, tighter, healthier vagina.

Material / Texture

There is a lot of design in this little toy:

1 - The inner 'egg' is a firm plastic. Inside is an inner ball that moves inside, knocking around, causing the kegel reflexes (and all the good benefits)
2 - The outer sheath is a non-porous Silicone, with ridges to better grip the vaginal wall (and for added stimulation). Because of the silicone, using only water-based lubes is recommended.
3 - The base of the egg has an indent, designed for 'easy in' control. Push in the smartball from this spot for easy entry.
4 - The silicone 'tail' allows you to remove the product easily. It is very stretchy and very firm.

The silicone is smooth and will not tug when inserted into the body. The ridges on the egg not only provide added stimulation, but an extra 'grip' as well. It is smooth where you want it to be smooth, and ridged where you want it to be ridged.
    • Bumpy
    • No odor
    • Smooth

Design / Shape / Size

The design is functional yet whimsical, as it looks like an over-sized neon sperm.

As shown in the above picture, every bit of the design has its own purpose. It is designed to be an 'easy in, easy out' toy.

Size specifications are as follows:

Length: 5"
Insertable length: 1 3/4"
Circumference: 4 3/4"
Diameter: 1 1/2"
Weight: 0.4 lb

With a circumference under five inches, the Teneo Uno is thinner than other ben wa balls, but it still may be too thick for some. (read 'Performance' section below)
    • Beginner
    • Ergonomic
    • Whimsical / artistic


This product did not perform up to expectation, but I am hoping my girlfriend's vagina is an exception to most...

My girlfriend first used this product when I was on the road, so I did not get to witness the use first-hand. She describes the Teneo Uno as difficult and uncomfortable to get in.

During use, she felt 'tight and full' and the product was uncomfortable. She could not feel the inner balls moving, and there was no stimulation. Only pain.

When she removed the product, it took a lot of pulling and effort. There was a small amount of blood on the smartball when she finally got it out.

She was also too sore for sex for 3 days. The second and third attempts were no better, and in this household, it's '3 strikes and you're OUT.' (especially since it resulted in 9 days of no sex)
    • Can be painful for some
    • Easy to use
    • Uncomfortable

Care and Maintenance

Because this is a layered product (plastic egg sheathed in silicone), cleaning can be tricky.

Clean with either soap and warm water, or use an anti-bacterial toy cleaner. Make sure to clean all parts of the toy, as fluids can get in the cracks and between the two materials.

Storage is easy, as it can be thrown into a drawer (or your toy box) when not in use. Just be sure to clean off any dust or hairs before use.
    • Easy to store
    • Hard to clean

Personal comments


There is a 2-star review of this product where the reviewer complains the product is too small. It went in easy, felt like a tampon, and she could not feel any stimulation at all.

Conversely, my girlfriend's vagina is too small for this product. Not only was it too tight for her, but it caused her to bleed and scraped her raw. Any vibrators/dildos we use have to be small. It's odd, because my penis is much thicker than this toy, yet this toy causes her pain but my dick does not...

To each their own.
    • Not for everybody
Follow-up commentary
Tried and failed, tried and failed. Just not a good toy.

Since getting this product, we have found a love for Ben Wa balls, just not this brand. Sorry Teneo... I tried.

    Thank you for your super helpful review! I also have a small vagina and severe pain issues. I will be looking for an easier and smaller excerciser thank you for saving me the pain your girlfriend went through.

    Thanks for this review! I have a problem with being too tight as well, so this "over-sized neon sperm" (still giggling about that) probably won't work for me.
