Not bad

Considering how it looks it doesn't taste bad at all. As for whitening my teeth it doesn't work to fast and I wasn't thrilled with the results. It wasn't awful but it was not what I was expecting

Works great!

This product worksheet amazingly! It also lightened my teeth by three shades! I would definitely recommend this product to anyone. My teeth felt so clean!

good stuff

I've been using this product and have noticed a difference my teeth seem whiter. then after a few months using this i kind of noticed that it just ends up staining your teeth this blueish tint so it makes them look whiter. I feel like all charcoal teeth whiteners do the same and is not a specific complaint about this particular brand.
