I started using Elise Pelvic Floor Exerciser over a year ago and after continuous use 3 times per week, I experienced a noticeable difference in leakage as well as the urge to urinate. I have recently purchased another Elise as the older model kept showing "LEAD" and would not function. My fault that I did not know you could buy spare leads and would recommend you purchase a spare set. During the time of malfunction of the original Elise and purchase of a newer model which looks the same as the older version, I found I re-experienced leaking and constant urge to urinate. After two weeks of using the newer model I am back to no leakage and less urge.
