The duo Smart Balls are made by the company Fun Factory. Fun Factory is known for great, safe and creative toys. The balls come with two balls connected with a thick piece of silicone and a silicone pull string to remove them when you want to. The smart balls are made of phthalate free, food grade and hypo-allergenic silicone. The silicone has a velvety feel to it, it feels like it has some grip to it. I personally have an older version that is light pink and dark pink in the insets of the balls.

This product is to be used in the vagina, to strengthen pelvic floor muscles. If you work on exercising these muscles, it is said you will have better orgasms and better control of your vagina. The balls have weighted balls inside the silicone covered balls, and when you wear them your muscles will be used. The balls also have a silicone coated string so it is non-porous all over. They are fun to wear and when you walk or move you can feel the weights move in the balls, creating tension on your vagina muscles.

You could wear the balls anytime to work out those muscles, it would be great to use during masturbation to give a stronger orgasm and use the muscles. I recommend these balls for every woman, at any age, from older teen (18) to older ladies alike, it is great for anyone who is a woman. The cleaning is very simple, you can use hot water and anti-bacterial soap, alcohol, or even boil them to clean them and prepare for the next use. The balls are also travel friendly and fit in a minimal amount of space.

This is overall a great toy to try if you ever wanted to try vaginal exercising, to strengthen pelvic floor muscles or to wear to stimulate the g-spot.

I love to use this toy during masturbation, to have a filled and better orgasm. I feel it has worked very well to sort of tone my muscles down in my groin area and inside my vagina. I love the way they move when you move, so you could walk around with them in.
