Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
The head part snapped of on first attempt of using the ear part so I sticky taped it on and was working fine as just a forehead thermometer but now not even 5 months later it’s just flashes red and says H even when it’s cold
It's a great device. It takes AAA batteries which is a big plus for me. Much easier to install and more convenient. I like the mode settings that allows temperature readings from the ears, forehead and body/objects.
