I really wish this was, like, a gel for running or something because the flavor is really tasty. Not too sweet, but flavorful enough to make sure you use it. It's a nice orange flavor that doesn't taste medicinal. I applied to the front and back of my teeth only and it lasted half the night. Quickly applied more and it lasted the rest of the night. I'm probably applying way too little but I genuinely just tried it so I'm not used to it yet.

Picture is deceiving .

Size: 1 Count (Pack of 2)

Picture of XYigel is deceiving as it shows two boxes. As it turns out you only get one box with two tubes in box. Picture should be changed to show one box

Didn't like the taste

Bought this to use for my mom, who sleeps with her mouth open. She did not like the taste, at all.
