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.

Nice refreshing flavor

Flavor Name: Spearmint

The bottle comes with a dropper that is easy to use and control the amount of drops to add. The taste is very pleasant and gives your mouth a refreshing feeling after use. Since the directions suggest a few drops per tank, this will last for a while making a good purchase for your money.
