Good product, satisfied customer :)
The Crest Whitestrips Classic work very well, Whithin 5 days of regular usage (2 30-minute sessions/day) I had noticeably whiter teeth, and my teeth weren't yellow before, but after you use this you'll notice the difference ;)<br />As to the pain complaints, there is indeed a small discomfort in the beginning, but it's no big deal for me, and after the 5th day, there is absolutely no more pain, nothing at all.<br />And if you put the strips on your wet teeth, they indeed don't stick well at all, but if you dry your teeth beforehand, the strips stay on very well, I can talk almost normally and they don't come off.<br /><br />Highly recommended!
