It really worked!!!!
I wish I had taken a before picture. Was concerned that I needed a light to use to whiten teeth. You do not!! This is amazing! I put it on for about 5 minutes and can visibly see a difference!! Very happy with this product!

Disappointed
As a fromer dental health care worker I have used many brands of whitener. The first sign this product was a dud was lack of peroxide buddles in the tubes and after a cumulative hour of treatment zero change. Expiration date said good until 2027 so either it is a false product or has be long stored at very warm temperatures.
