Does not stick!! Popped off my note 9 after a couple of days. I followed the installation instructions. I wish I would have read other reviews before I wasted money on these.

My daughter has this & is not using the crystals that came with it because not all her brushes would fit if the crystals where in the bottom. She wishes the price was lower but is using it on her desk.

This product cleans the nose very well. The suction is strong yet gentle on skin. I would highly recommend this product to anyone who has blackhead issues. Good for both men and women.
