I've always used this brand with my own trays. Usually this material is strong, which agrees with the reviews of others. However, this latest version seems to be quite weak. There is a slight minty flavor and a slight tingling sensation in the gums, but after leaving it for more than 20 minutes there was no effect. Usually if you left it on for too long your mouth would burn like crazy. After a few months I could not see any improvement.
