Review (2/5): Directions very unclear...ruined my product
All the directions state about the trays is: " Place thermal tray in hot water (200 degrees) and get your teeth impressioned." Nothing about how long to put it in the water to allow it to mold to your teeth. I held the tray in the almost 200 degree water and it basically melted in less than 10 seconds. I had know idea how I was supposed to go about doing this and because the directions were unclear, I was unable to use this product. The trays cannot be fixed once they have basically shriveled up into nothing. For kicks, I did the second tray and held it in the water for about 3 seconds. So for those of you interested in buying this product, do not place the trays in water for more than 5 seconds.
