Review on Reusable Forehead Temperature Strips, Instant Read for Daily Home Use and Travel - Multipurpose (Pack of 20) by Gin Bajema

They don't work for me - IF I'M SWEET. It was 91ºF and I was outside and came in and decided to give it a try and thought they were useless. a digital thermometer used by healthcare professionals to screen you for fever or illness prior to entry. That's why it didn't work. I tested a few later when I had cooled and they were accurate and showed the colors as instructed (on each) - when my forehead is dry. Tried them on another person who were originally dry and they fit perfectly. They work well for IFAK, camping gear and other storage areas and are reusable making them great value for money. Flexible and easy to store. Love her. I think the reports of them not working could be because they were testing someone with sweat on their forehead OR NOT LOOKING IN THE MIRROR TO SEE COLORS. COLORS DISAPPEAR WITHIN 2 SECONDS. USE THE MIRROR AND THEY WORK. It might not be for you because it's so simple. Look closely at the temperatures so you understand that they operate in a very narrow range of temperatures, so a regular thermometer or digital thermometer has many more numbers to look at.
