I have tried the Elvie. And I love the immediate biofeedback because it's hard to identify those pelvic floor muscles. Plus I love the design and the look (it's not pink). And with practice, you get results.
Elvie is available in my office. You can go to Elvie.com. If you enter the Discount Code - TodaysWoman20- you will get a $20 discount on your online purchase. Yes!
