I have never written a review on a product, but the design of this toothpaste tube cap is absolutely terrible. It is very messy. It gets in the way of the toothpaste and toothbrush. When the toothpaste gets on the cap, it's a mess to clean up and most of the time prevents the toothpaste from getting on the toothbrush. It also breaks off the tube and creates another mess. I have used Crest toothpaste for many years, however, I am thinking about changing brands because of the toothpaste tube cap.
