This is the weighted Kegel exerciser for women that uses vibration therapy to help strengthen the pelvic floor and help eliminate incontinence. The waterproof device gently stimulates the pelvic floor muscle via 10 different vibration patterns, promoting strength and healing without surgery or other invasive techniques. With three different weights (10g, 30g, and 45g). Made of latex-free, body-safe silicone. Washes with soap and water. Charges via USB; a full charge provides up to 90 minutes of power. A free app connects the exerciser to your smartphone to adjust the vibration intensity and patterns.
