Works fast and love the bonus FCP enamel gel...
After trying many teeth whiteners over the years, I have found the Watts Power brand to be the most effective. The bonus of the FCP enamel gel makes this refill set perfect for fast whitening in additon to the health of your teeth.<br />The very large gels offer many many applications and also provides extra for touch ups. Saves your time and money....
