Query: Worst toothpaste ever!

This is perhaps the worst toothpaste I have ever used. The paste came out like running water. By the time I put the toothpaste on the brush and put the cap back on the tube, 90% of the toothpaste that was on the toothbrush had dripped off into the sink. Buyers beware of watery toothpaste; you've been warned!!
