I had a very uncomfortable experience with my Uno. I can't ever imagine having the Duo. Getting it in was painful and taking it out was painful. I used natural lube to put it in and take it out, which worked for me just fine but it stretched my opening. Maybe it's because I am so young that it did this to me. I personally think that it needed to be heavier and smaller.

The Teneo Uno Smartballs from Fun Factory can improve overall vaginal health, by causing your pelvic muscles to involuntarily contract while the product is being used because of the inner bead that rolls around. You just have to be moving! The product is inserted like a tampon and feels like a tampon because sometimes I didn't notice it.

I loved the material that it's made of, especially since it's on the safe side. It is a non-porous silicone, with ridges to better grip the vaginal wall. The string is also made of silicone, which allows you to remove the product easily. It won't break even though it is stretchy.

The design is awesome and artsy, that's probably what attracted me most, especially compared to LELO beads.

Size specifications are as follows:
Length: 5"
Insertable length: 1 3/4"
Circumference: 4 3/4"
Diameter: 1 1/2"
Weight: 0.4 lb

Even though the circumference seems small, it was too much for me. I will be buying LELO's mini pleasure beads because it is recommended for women under 30 who have not had children, LELO's circumference is 3 3/4".

I didn't like the way it fit inside me and only occasionally did I feel the inner ball rolling. The best part about Smartballs are the colors and the way it looks and feels with your fingers. Other than that, I can't like it. If you are under 30 with no child I would reconsider.

Cleaning was pretty easy. Just use anti-bacterial soap and/or toy cleaner with warm water. Make sure you clean in the ridges, which really isn't that difficult. I store mine pretty much anywhere. Right now it's sitting on top of my vanity area. I just wash it off before using and go.

The Teneo Uno came in a very stylish box and came with more instructions that I was willing to read. While the box isn't discreet, it was awesome to look at and the magnetic closure on the box was a great touch. Free lube was included which is nice but I am not sure I will use it since I only use natural lubes.

Not all women are the same so give it a try but understand your mechanics before getting this.

My partner liked the way it looked and was interested in what I was doing. However, even he said they looked too big for me.
