Don't use when you're in a rush!!!
I bought these for my children and tried it with them.  Taste isn't the best but isn't the worst.  They do turn your mouth completely purple and you can vbery much end up scrubbing your tongue and teeth more than the recommend brush time.  Also I have a white bathroom sink and didn't have the water running while brushing and splitting and it did miscolor my sink but with a little scrubbing I did get it to come off. Hate to say it but it's best to keep water running in your sink when using this product.
