The Smart Balls Teneo duo is my secret weapon in my sexual arsenal. I can use them with or without a partner, while masturbating, while running errands, even while at work. These balls are designed for exercising the muscles of your pelvic floor, but these balls are so versatile that they do more then just give you a work out.

The balls can be used for penetration while you are using a vibrator on your clit. It gives that full feeling and you can place a vibrator on the end of the ball to make the inner balls inside vibrate! The balls can be worn all day long so you can exercise your muscles throughout the day. I have done this and find that it is incredibly arousing and great foreplay. There's just something about walking around with balls in your vagina and nobody knows but you! You can also use the balls without wearing them for long periods of time, even a few minutes a day will help get your muscles toned.

The balls have a cord attached to them making removal easy. If you aren't done with your duo you can play tug of war with yourself or with a partner. It's a great PC exercise to practice and can lead to other fun.

The duo balls are made of silicone which is non porous. Because the balls are silicone, they create drag. To eliminate that, use your favorite water based lube. The balls have no smell, taste, or weird texture to them. The balls are ribbed which adds a little extra sensation when inserting them. The real difference in these balls vs others on the market is that these balls have a smaller ball inside that moves around and causes vibrations.

The balls are a good shape for an average user of average size. If you have a very small or short vaginal canal, these balls may be a bit uncomfortable, or may stick out. This toy will travel easily with you no matter where you go, because it can stay inside of you. If you need a break, it will fit anywhere of your choosing. The balls don't look like a sex toy and can be mistaken for something else.

The things I like most about this toy are the inner balls and the ability to wear it anywhere I go. I can't take my vibrator to work, but I can wear my smart balls all day long.

Smart balls go anywhere you do and can be easily stored in really, any location. They are discreet and can be hidden among other objects.

Because smart balls are silicone, you'll only want to use a water based lubricant with them.

The balls can be cleaned with soap and water or with your favorite toy cleaner.

I wore my smart balls while writing this review just to be fair and now I can't wait until my husband gets home from work!
