My feelings, too. I just tried them. From reviews on Amazon and elsewhere I'd say that 60% of users are satisfied with them, 40% aren't. They worked, some, but not all night and no better than frequent uses of Biotene mist which is what I used before and since.

I'd say it's worth a try for anyone.
