Does not apply well
This product is too expensive for the size of bottle to not have a smooth easy application. It is sticky and tacky, does not go on evenly or smoothly. When you try to cover a streak, it just looks gooped up and worse. Also the bottle came with polish leaked out. It's a great idea for ppl like me with high tooth sensitivity that prevents traditional whitening comfortably but poor execution. I hope I can return.
