I've tried other kegel exercisers before, and this one is in a league of it's own. It's super-efficient and allows me to fit in kegel exercises just before bed. I love that it adjusts the "workout" according to my body too -- how ingenous!
Great versatility! I love that I get to work my pelvic floor, and get a massager and vibrator too...that's 3 in 1! The only thing is, I wish it were rechargeable, but it says 1 battery lasts for 200 routines so I guess is not too bad.
