I also do not prefer CADI thermometer. I keep getting different readings. Probably it is only my set having problem or so. My son was having very high fever, but the reading says 37.5, after which i scan again, it says 31.1, then it says 38.2. I am totally stressed up because fever is no kidding matter and giving me different readings making me very hard to keep track of my son's fever.
I will throw away my CADI and go fro Braun instead!
