Review on GEKKA Infrared Forehead Thermometer for Adults - Wall-Mounted Non-Contact Digital Temperature Thermometer with Fever Alarm - Accurate Instant Reading LCD Display for School Office by Michael Lucas

I bought two K9 units for a manufacturing facility. The concept of quick measurements, alerts and the convenience of quick body weight checking is amazing. However, all values are low. An employee claimed he had a fever and was working all day because the device showed a temperature of 95 degrees. One employee tested positive for COVID that evening and actually had a temperature of 104.5, which infected several employees. Revain says my return period has expired so I tried contacting the manufacturer and asking them to honor their 12 month money back guarantee. I had to click many links, starting with Revain, to find a chat that supposedly sends messages to the manufacturer. The response was a promise to call back within 2 days but the messenger didn't ask for my phone number.
