Taste is Weak Mint
Size: 1.5 Fl Oz (Pack of 2)
I tried another brand and liked it better. It was more minty than this one. It has a mild aftertaste. I can't tell one works that much better than the other. But it was at least something to spray in my dry mouth, so it worked.

Most cost effective product
Size: 1.5 Fl Oz (Pack of 2)
I have an issue with my mouth going dry due to CPAP use. This spray is better priced than other sprays but, not quite as refreshing. Due to the cost savings, I will continue to order this product.

Awful taste
Size: 1.5 Fl Oz (Pack of 2)
It tastes terrible, and after trying to get used to it, it didn't work. I have used it three times a day and I still have no benefit from it. It feels very dry at night and aggravated my dry mouth when I woke up. I also purchased the toothpaste and the mouthwash to go with it and it was a total waste of money.
