Double Love Balls for Kegel Exercise & Stronger Orgasms

High-quality double love egg for pleasure & vaginal toning

Ideal for women who enjoy a fulfilling sensation

1.25 x 1.5 inch diameter balls with soft loop for peace of mind & easy removal

Body-safe silicone - hypoallergenic, hygenic & 100% body-safe

Designed & crafted in Germany by innovative sex toy designers Fun Factory

Smartballs Duo are high-quality love balls from sex toy innovators Fun Factory and have been recommended by Doctors, sex therapists and mid-wives since they started producing them in the 1990's.

This double set of love balls contain small weights that roll and rumble as you move, making your muscles work harder. Strong PC muscle is not only about tightening and urinary control, but also about stronger, more intense and more consistent orgasms. It's believed that women who enjoy G-Spot orgasms are likely to have super-fit kegals

Tapered for easy insertion, with a 'finger-dip' indent on the lower ball to ease insertion and a retrieval loop for peace of mind, Fun Factory SmartBalls Duo are made of silicone & medical grade plastic, ensuring they are body-safe, hygienic and easy to clean

Want to tone up your pc muscles after giving birth? Want stronger, longer orgasms? Want a bit of a warm-up before a hot night in? Fun Factory Smartballs Duo are perfect for all of the above.

With a combined playable length of 3.5 inches and each ball 1.2 inch diameter, this double set of love balls are perfect if you prefer a fulfilled feeling inside as they're large enough to stimulate your G-spot as you clench around them.

Our toy tester found that the Fun Factory Smartballs Duo can be worn comfortably for hours on end, building up fantastic g-spot stimulation and keeping the mind playful and body aroused.

We recommend coating SmartBall Duo in a drizzle of water-based lube, to ease insertion and enhance glide and sensations.

Excellent pelvic floor workout.

I thought i would experience some of the incredible sensations some of the reviewers describe but it wasn't the case for me. This doesn't bother me too much because my idea was more to use it to make sure my muscles keep toned. Apparently it works without us being aware of it, so i'm ok with that. Although the balls are not that big, it is easier and kinder to use a little bit of lube and to insert them while lying down. For me it tends to have the same effect as when i wear a tampon, i feel a slight pressure on the bladder so i need to pee more often.


They have made such a difference to just doing kegels alone and have certainly helped give some excellent muscle control and general tone - the end result being a much tighter vagina and a greater ability to orgasm. They can be worn while you're working, walking or just lazing around. If used for a while before sex, I have found I orgasm more quickly and more intensely usually. Though they also feel divine after sex, letting you prolong your own pleasure for quite some time.


I bought these for my girlfriend. She has not used any similar balls before.Initially she felt that they seemed quite large, and following a shower she tried to insert them, but without lube. Unsurprisingly perhaps she was unsucessful.Next time we put them in together using "Lush" lube. Once in place she loved the feeling.She kept them in while we enjoyed a vigourous sex session (anal) and they are now a firm favourite.The "tag" seems strong and you do not feel nervous about not being able to retrieve them, and the finish makes them easy to clean.
