Wow! I really like this Grinigh coconut oil whitestrips. It has a great bonding unlike the other whitestrips I have tried. It is much easy to put on my teeth. It is much comfortable than the other brands and less residue. I leave whitestrips on for 60 minutes. It is a least a shade lighter than before. I can see the difference. The best thing about this whitestrips is that it smells and leave a coconut fresh breath. I really recommended if you are looking for alternate whitestrips. #sponsored #rankboosterreview #grinigh #whitestrips
