Smartballs Teneo duo - sex toy by Fun Factory - review by CaliGirl

A whole new excercise ball

I wish the inner ball rattle was stronger so I could enjoy it more often. Other than that I absolutely loved these balls. They are a great size and stay put once in. They come in a wide variety of colors & will win over your heart the first time you use them.

Couldn't really feel the rattle of the inner ball

useful review


These are the new wave of vaginal exercise balls, and I must say that they are definitely improved from the older slick styles. I think that anyone that has a vagina should try these. They do look big and a little scary, but just use a little water based lube (by the way a small amount of Fun Factory lube comes in the box) and give them a spin.

Material / Texture

These are made from silicone which is a huge plus; one of the safest materials out there. But since they are silicone, be sure to remember that you can only use a water based lube with these.

Maybe I'm weird or paranoid but I always feel that when I leave silicone inserted in me, that there is an odd light odor on the toy after which is gone as soon as I wash it.

They have a very slight raised design. I am not sure if that is supposed to help them stay in and be less slick, or just for looks but once they are inserted you cannot feel the texture at all.
    • Bumpy
    • Light odor

Design / Shape / Size

I like that unlike traditional balls these are a little larger and held together with a short silicone attachment. They also have a grooved little area for your finger on the bottom of the last ball. I like that and it helps with insertion especially when using lube.

I have mixed feelings about the silicone string-like hoop that is attached at the bottom. It makes pulling them out an easy task, but once they are in it is still just hanging out of you and can be an odd feeling.

The length is 7.25", circumference is 4.75", Diameter is 1.5", and a total weight of 0.3lbs.

They also have an inner ball that rattles around to add a little reminder that they are there. It isn't a strong vibration but yet a subtle, "Hi I’m here, don't forget to use me".

I like that they are not super slick and that for the most part they stay in place. They are so much better than the glass or other slick smaller balls. I have been using these for a few weeks now, and I can tell a big difference in my vaginal muscles. Not only do I feel tighter, I can also squeeze him harder during sex.
    • Comfortable
    • Discreet sound
    • Easy to use

Care and Maintenance

Since these are silicone, they can last you a very long time if you take your time and care for them the right way. After washing and drying you could use the original box that they came in. I usually keep all of my smaller items in separate little baggies after I am done cleaning them.

There are a few cleaning options for these. You can put them in your dishwasher, boil them, and they are also bleachable (I haven't tried that but I would suggest diluting 1 part bleach to 10 parts water and rinsing very well).
    • Easy to clean
    • Easy to store


These come in a nice little box that has a magnetic flap which opens like a book so you can see inside. When opened from the top you can slide out a plastic clear "case" that you could use to store them in if you wanted.

Inside is a small sample size of Fun Factory lube and a direction sheet. It did take me a minute to find directions in my language, since there are so many on the sheet! Honestly though these are so easy to use that you really do not need to read the directions pamphlet.
    • Good for storage
    • Very informative

Personal comments

Almost every time I use these I get pretty wet all on my own. Not like it makes my panties wet, but definitely noticeable. They are a great fun way to work on your vaginal muscles and you can even tease your partner by letting them know that you are enjoying every minute of your workout!
Follow-up commentary
I still like using these balls over the other ones that I own. I think that anyone who has tried the smaller balls should try these. Everything about them is better than the old style balls.

    I'm glad you like these! I had the Uno (single ball) and I loved the deep rumble, but it was uncomfortably and often panfully large for inserting and removing. I switched to the mini luna beads and wouldn't ya know, they just didn't have the rumble I loved like Smartball! So now I'm buying the Bedroom Kandi set! I SWEAR I am going to go broke buying these blasted balls. Lol. They are so fun and entertaining though! I so wish there was a mini Smartball that was small enough to fit me. I'd have to buy it too. Thanks for sharing. It seems like these work for most women than not, so I guess it's just me. Ugh.

    My partner found these to be on the large size for vaginal balls as well. Glad you're enjoying yours. Thanks for the review.
