I have a fairly small tight vagina, so inserting both of the balls was uncomfortable and give me a bloated feeling. I tried inserting only one ball and allowing the other one to hang so that it pulled on the inserted ball to give me more of a work out, but the balls are so large that it stayed in there on its own. A downside to the balls is the center seam where the two spheres of the balls are joined. The seam is raised. The balls themselves are hard plastic, so they are easy to clean. Just a little anti-bacterial soap and hot water does the trick. The twine or rope connecting the balls do absorb water, fluids or what ever it is soaked in. I don't believe that the balls themselves are sealed because they do fill with water if you submerge them in the water for too long. I give this product an F- for the hygiene.


These are decent for the price, but as mentioned, they are on the large side, so you do not have to work very hard to keep them in. They are roughly 2" in diameter, so depending on your anatomy, they may or may not be too big.


The price is great, but you're better off spending a little more and getting a better product that you will get more use out of. I think this product is an excellent item to give as a gag gift to one of your girlfriends.

Also, these do have heavy metal balls inside the plastic shell, but you don't really feel them moving around. Unless you are literally running around or making fast, awkward movements, if you're just walking around the house or cleaning, you do not feel much movement. If you jump around, you can definitely hear them bouncing around in there.
