The dissolving strips just don’t stay on well enough to work. The first few attempts they got really sticky, and a section would stick to my gums and pull off my teeth. I tried putting them on shortly after rinsing with water so there’d be a little more moisture, but then they slid all around. Either way they aren’t on the teeth they should be whitening.

Tried to like this product, but the strips are goopy, and end up sticking to the inside of the lips. Some of the strips are so thick they are almost like plastic and don't stay on the teeth. I have not noticed any actual whitening. For Snow, this is for sure a sub-par product. Don't recommend
