Great product
I love this product. It is true what other say about the sensitivity. I would recommend using sensitivity toothpaste while you are using the strips, it helped for me. It made my teeth noticeably whiter. I would suggest you take a picture of yourself smiling before and after. I noticed the whiteness of my teeth when I saw a picture taken recently and I couldn't believe how nice they looked. I just had to dig up an old picture to compare and it was a big difference. After I have noticed this in the new picture, I love smiling for pictures now and showing my teeth. I was alway self conscious about it before.  That alone makes it worth the price.<br /><br />I was very satisfied with my results. Make sure to read all the instructions before using.<br /><br />It just became a part of my bedtime routine, not a bother at all. I just put one on while I was watching my evening TV programs and just kept an eye on the clock.<br /><br />Also, I recommend that after you have finished your pack that you use the Crest whitening toothpaste.  It really helps to keep your teeth staying white.<br /><br />Great product and it was recommended to me by my dentist.
