Title: They were disgusting and very disappointing
Review: I found crest whitestrips to be very impractical and inconvenient. I used them on both upper and lower as directed. If I would swallow or move my mouth in any way, the strips would end up moving and bunching together. Most times, I would put them on my teeth before walking so they would have a chance to work properly and I could concentrate on not moving my mouth. After taking them off, there was a thick film left on my teeth that almost made me throw up. I would have to scrape it off and keep spitting out the rest. I did not see much of a difference in my teeth after fourteen days. Compared to the Colgate white strips, there is no comparison.
