The Smartballs Teneo Uno by Fun Factory is a vaginal exerciser used for increasing PC muscle strength and overall vaginal tone. Women with strengthened PC (pelvic floor) muscles are likely to have a better sex life and have an easier time having orgasms. These muscles when toned can also minimize problems with urinary leakage. There is a ball inside of the smartballs which moves and "vibrates" when you move around. These vibrations stimulate the PC muscles to start contracting.

The Uno is made of silicone which rates a 10 on Eden's safety scale. The texture is ribbed and velvety. The ball feels hard because of the underlying plastic, but the silicone covering is less firm and has a lot of drag. This ribbed texture stimulates you internally especially when the internal ball starts vibrating. Uno is completely waterproof and is made of hypo-allergenic food-grade materials. It is also free of phthalates, latex, and is nonporous.

Teneo Uno is 5" long with an insertable length of 1 3/4". The circumference measures 4 3/4" with a diameter of 1 1/2" and weighs 0.4 lb. The ball is inserted and there is a retrieval cord which hangs out 3 1/2" beyond the end of Uno. I found this to be too long and it bothered me slightly while wearing it. The base of Uno has an indentation which is supposed to make inserting with one finger easy. This is a design change from Fun Factory's original Smartballs. The Uno also came with a sample of Toyfluid, a water based lubricant.

Uno can be very discreet and travel friendly. It takes up very little space and it completely unnoticeable when wearing. I think the size is pretty user friendly and will fit the average woman. I personally needed something slightly larger to get the full effect. I barely noticed the ball once it was fully inserted. It needs to fit correctly to stimulate the PC muscles to contract. The design is not realistic at all. The Teneo Uno comes in a variety of color choices as seen on the product page.

Teneo Uno has a hands free feature that sounded appealing to me when purchasing this product. Honestly, Uno was too small for me and had very little to no effect on my vagina. Tugging on the string made me feel the ball and made me slightly contract but undisturbed this ball had no real effect. I think it should work just fine if the ball fits your vagina correctly, if you tend to enjoy girthier toys this one may be too small to work.

Caring for Uno is quite simple. Soap and water cleansing or using a toy cleaner is fine for daily use but Uno can be sterilized in the dishwasher or be boiled for a few minutes. Water based lubricant is the safest choice for Uno since silicone lubes may possibly degrade silicone toys. I store my Uno in its clamshell package.

Teneo Uno arrived in a red an silver box with a clear plastic window which displays the ball. The plastic clamshell inside houses the ball. The back of the box has a magnetic fold out which has additional information. The packaging, although not discreet, looks clean and provides a lot of information about the product.
