These are the best kegel exercisers that Fascinations has!!! This is the only one that actually gives your vagina a workout, haha! It's 3 different sized/weighted balls, and you gradually increase weight and decrease size as you get stronger. So it actually is doing something! They are a really nice silicone material, super easy to clean. The box is convenient to have for storage. The only thing that bothers me is the string hanging down, but it's fine because I'd rather have a string than no string like some other ones (how do you get those out, jeeze!)! It's like a more noticeable tampon string. I use these to get better at strapless strap-on sex, but they're also great for anyone with incontinence, or if you've just had a baby!
