Traditional Ben Wa balls have an additional interior ball to generate a small amount of inertia when moved slightly. Although these do not have that, the weight, in my opinion makes up for that. It does not generate quite as much inertia, but still enough to be a stimulus instead of just a "vaginal wall exerciser." The weight of these, although, does make them a good stand alone exerciser for the less sensitive. The presentation is also nice, they come in a clear plastic wedding ring style case (opens up on a hinge in the back) and are stored in a foam cut-out so they don’t move around and clank inside the case.

I got a set of these not quite ben-wa balls for my partner in crime, since she is sensitive and doesn't need a whole lot to get her going. These balls turned out to be the perfect size for her; since she's a little tight the diameter works quite well. They move around together and separately whenever she moves, laughs, or even most other daily activities, causing her a good amount of stimulus. Other people might not feel as much, but still enough to get the water works going, I think...

Quite heavy for the size, and combined with the finish, these lead me to believe they are a form of polished or stainless steel. Very easy to clean, and actually look nice, since I hate the look of plastic that has an obvious seam line, or cheap looking rubber. I am very material safety conscious, and don’t like using anything that isn’t up to my standards, which is generally a five or above on this rating system.

A great product, especially at this price, but be warned, they are not a product intended for anyone who needs a rabbit to get off. These are definitely a gentle, continuous and varied stimulation product for those who like to enjoy themselves without the constant need for over stimulation that seems to be running rampant today -_-

These, and all other unlinked balls are best used put inside a condom so they are easy to take out, unless/until you are confident in your removal abilities. It can be tough, especially if you are like her, and even having a hand on you causes you pleasure, let alone digging around for a now slippery metal ball.

Still amazing, just the right weight and intensity level. I've been pounced at home after my partner wears them for a day, which is to say, a very pleasurable experience for both parties involved! I've been told to say that it's quite the exhilarating sensation to have something pleasuring you very softly in public that no one else could know about.
