I love whitestips, so I figured I would try these coconut oil strips instead. I used them for two consecutive nights, and noticed a little sensitivity, so I skipped the third night, and the sensitivity subsided. I like to wear strips while overnight, and I thought these would be better for this. I do not see a difference in my teeth color yet, but they are easy to apply and come with a very impressive box, insturctions and a color chart to see your progress. I will certainly purchase again if I notice an improvement in color. #sponsered #rankboosterreview #Grinigh #coconutoilwhitestrips
