Negative Positive
Title: mediocre compared to canker cover
Review: These are much harder to place and last a much shorter time than Canker Covers. I'd say they last at best 45 minutes, whereas Canker Covers last an entire night's sleep. And while Canker Cover adheres almost instantly, Canker Melts must be held on--and kept dry--for about a minute to adhere, and even then they tend to fall off. The only advantage these have is that they can go somewhere visible, like your inner lip. Canker cover is too big and gloopy for that. Other than that, these are so-so short term relief at best and I see no reason to buy them over Canker Covers.
