These balls are made for vaginal exercises. These shouldn't be used anally because they're plastic and the cord is nylon. That means that they aren't able to be sterilized. And the cord is too short so there's nothing to keep these from getting lost inside a butt. Though the cord can be very useful when you use it vaginally, weight can be added for even more intensive training. Also since the balls are only connected by a string, more advanced users can move them around using only their muscles. But that is definitely for more advanced users. These balls also have small balls inside them, so they move and level the center of gravity, which can be useful for beginners. Also these small balls inside create an effect of "vibration", which is quite fun and pleasuring. Also you can use them along with clitoral stimulation or during anal sex, which also can bring new feelings. What is good about these balls - you can use them anywhere. You can go for a walk, or a ride in the car or something and no one will know that you are wearing them. It might be a problem in very quiet places, because the little balls inside make sound when they move. But I don't think anyone will guess what this sound is.

The balls are made of plastic, which is smooth, nonporous and odorless. The surface is covered with a gold paint. I didn't use them enough to notice myrself, but I've heard from a friend that the paint can peel off with extensive use. The surface is quite smooth, except these small pits, which feel quite pleasant under my fingers. And also there is a connection seam on each of the balls. But I don't think it will cause any discomfort. I can barely feel it with my fingers. The string between the balls is made of nylon and is very strong.

Generally I like the design. Round balls covered with golden paint and with little craters on the surface. Some say they look cheap, but I don't think so. Actually, they are cheap. So they look good enough for their price. I like the gold color, and the weight is just right - about 0.2Lb or 4oz. The diameter of the each ball is about 1 1/4". The connecting string between the balls is about 1/2" long, and the retrieval loop is about 2 1/2" long.

All in all, that toy is definitely not for me. My vagina is more on the tighter side because I haven't given birth and have only started my sexual life relatively recently. So these balls appeared to be too big for me. It was quite easy to insert them with the use of a lubricant. But I didn't have to make any effort to hold them inside, though I'm a beginner and my muscles are not very strong. At first the small balls inside were "vibrating" when I moved and it was quite funny and even pleasuring. But after some time, the balls moved up and I stopped feeling this "vibration". I needed to jump or do something like that in order to feel it. And also as the balls moved up inside of me I barely stopped feeling them at all. And from the very beginning I didn't feel these "craters". So I don't know what they are there for. I tried to use a clitoral vibrator while the balls were inside of me, and I didn't feel any difference. Even there was some discomfort. And finally the worst part for me was extracting. I had very big difficulties when taking them out. That was really hard and what is more important, really painful! Now I don't want to put these balls inside me anymore.

It can be quite hard to clean these balls because of the pits on their surface. They are not very deep, but that's enough for collecting lubricant and other fluids. Also the nylon string is quite hard to be cleaned properly. I used the balls only twice and it already became less white than they used to be. I tried to soak the balls in a special sanitizer for several minutes - I think that is the only way you can clean them entirely and completely, though washing them with warm water and antibacterial soap can be another good way to clean them. And also I should say that because this product can't be sterilized, anybody using them shouldn't share them with anybody else. They are definitely created for individual use only.

These balls come with a plastic box, where they can be stored. The box is made of transparent plastic. The bottom part of the box is a pink color and the upper part is a white color. I really like this box. For me it's a very convenient way of storing the balls. Actually, I think, it would be better if the box was non-transparent. But that's a matter of taste.

These balls became my first vaginal exerciser. Before buying it I read many articles in the Internet about kegel exercises, and in almost all the articles, they mentioned vaginal balls or eggs. I've decided to try the balls, because they seemed to me easier to start with. I have choosen these particular ones, because they have a cord, which I can use to extract them. The smaller ones didn't have the cord, and I was afraid of loosing them inside of me. But these balls appeared to be too big for my vagina, so now I'm searching for something much smaller.
