Whiter teeth noticeably

I use these whitening strips often and get compliments on how white my teeth are. There is a good amount of strips for a good price which does the exact same for double the price name brand. I keep them on for 30 mins while i do my makeup, usually twice a week. Altho they do make my teeth very sensitive, any type of whitening will. Alot of saliva in ur mouth might cause them to come off easily tho so try to keep ur mouth more dry.
