I was provided several samples of this product in the mail, out of the blue. I decided to try them to see if they would have any effect.

I followed the instructions that came with the strips. These had a really hard time adhering to my teeth, and were constantly flopping around in my mouth. After some time had passed and it was time to take them off, my saliva had made the strips so flimsy and slippery that I could barely get a grip to remove them! They tore off in pieces.

I don't feel that these were very effective in whitening my teeth, even after following up with the sample of Crest 3D White Toothpaste that this came with. I went through all of the samples over the course of one month, even though they were a difficult nightmare, and they did nothing.

I can get a tube of whitening gel from my dentist for less than a box of these, and it works way better.

Do not waste your time or money. I followed the directions step by step and after 1hr I was extreamly disappointed, my teeth were no whiter than before I put them on. Then a little while later my teeth were in intense pain, they were so sensitive it hurt to breathe. These are horrible do not buy them!!
