The Minna kGoal is an interactive system for exercising the pelvic floor. This little device fits inside the vagina and measures its squeezing strength, delivering vibration as biofeedback. It can also connect via Bluetooth to a smartphone or tablet, allowing users to track their strength and endurance over time. Pelvic floor strength is a key component of sexual (and overall) health, and kGoal provides a fun way to build strength and control. kGoal is made of medical-grade silicone, is splash resistant and is USB rechargeable.
