Ionic White Tooth Whitening System

Has anyone tried the above which is selling for just under $30 (http://www.ionicwhite.com/?cid=245738; watch the video)? If yes, what is your experience?

From the infomercial, this system seems to work. It is better than laser whitening in that the system whitens both the front and back of teeth. (However, it seems the light unit is not large enough to reach teeth at the back and so I am not sure how those teeth will be whitened.)

If your are in the dental profession, how does it compare with conventional tray bleaching from dentists? Tweet
