Review (5/5): Better than colgate
Believe it or not these whitening strips are better than name brand such as Colgate.
These strips actually stay stuck to your teeth. The colgates always had issues with them slipping off, especially the bottom piece that was near impossible to get on.
These seem to have a heavier film than the colgate, expect to need to brush after using them.
Also pay attention to the directions, the Colgate very simple "How to use" yet I found out this brand actually has disclaimers to NOT use right after brushing, and discontinue using after 2 weeks, this was never mention in Colgates.
