THIS.REALLY.WORKS! Holy guacamole! To be honest I thought it was nonsense and that the photos were photoshopped, but NO. It's legal. I also used it exactly as they instructed. Luckily I took the photo before I started because when I did I thought it would stain my teeth more for some reason. So I took another photo and compared them side by side. It turns out they are MUCH whiter! I PROMISE the only editing I did to my photos was to zoom in so you can't see my bad skin and missing makeup. These were my true results and yes it was after just four uses! The only thing I don't like is the case in which the device is supposed to be stored. It is almost impossible to use it in real conditions. Oh yes, mineral water. They don't give enough to make you want to use it every time, but I can't count that on the amazing results I've had!
