Works
It definitely pulls off more dirt into the cotton pad than when I don't use it, but I'm not so sure about how well it 'preps' my skin for moisturizer absorption.  After using it for a while (maybe one month), there doesn't seem to be a big difference between the high and low vibration settings anymore.  Oddly, the low setting seems to have gotten stronger over time and really buzzes quite violently, as if it's on the high setting (which it's not).  So it's very noisy to use, but other than that, it seems to clean well.<br /><br />I use it nearly everyday and only need to charge it about once a month, so it lasts much longer than the estimated 10 uses per charge!  I really like how I don't have to be plugged into the wall to use it, and I'm free to roam around (5minutes per setting is a really long time!)
