I'm Amanda Olson from IntimateRose.com, and I'm a physical therapist specializing in pelvic floor rehabilitation.
One of the questions that we are commonly asked at IntimateRose.com is, “Is there a vibration mechanism in the weight?”
The answer is no: It's just a weight covered in body-safe silicone that's BPA-free, non-toxic, and non-porous.
So it's just a weight, and there's a progression of the weights according to the color.
So as the color becomes darker, the weight becomes heavier.
That is really optimal for strengthening the pelvic floor, and it's easier to build strength, and be able to coordinate that strength, without vibration.
