Works better than any of the others I've tried!!
Size: 1.5 Fl Oz (Pack of 2)
Not the greatest tasting but works so great that taste is irrelevant! Actually tastes like cinnamon not mint which is A OK with me! It is the best working and longest lasting of several I've tried. Finally! My search for something that works is over!

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.
