I used these with my first pair of lenses from PP and I have to say that the Jitterbug is REALLY good! I've used it everyday that I wore my 30Days and regular lenses (at least an entire month now) and I didn't get the gritty feeling of old lenses at all. My lenses always feel fresh when I put them on now and the countdown timer takes the guesswork out of replacing lenses. Very happy!
