Great product.
Flavor Name: Grape
Easy to use. Well worth the money as it's highly concentrated. The grape flavor is subtle and not overwhelming

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.

My breath stays fresh longer
Flavor Name: Spearmint
I just add a few drops to my water flosser, and it makes a big difference in how fresh my mouth feels afterward. The spearmint flavor is light and not overpowering, which I like
