Gonna do something I never do, write a review after only 1 day! Compared to everything else I've used, this is clearly the best for my lowers, especially since my lowers have been trimmed to help them fit comfortably, which may have been a mistake. I used the thin tapes which never held. Used the paste which was better, but messy. Used the thicker strips by P*ly**** which were better than the paste but every one came loose after eating firm foods, or about 4 hours. I was ok with using new adhesive more than once per day, but I tried these today and I ate every hard and crunchy food I wanted and drank lots of liquids and still had to pry real hard after 4 hours to get them out! Love it! I will probably try them on uppers as well, as one review said (I currently use the solid sheet for uppers which works quite well), and if that's good enough, I might even try eating caramel or taffy!! NOT something recommended for most adhesives. Now I have to get used to having dentures in for more than 4 hours. Looking forward to that.
