Bests & Worsts Reviews from Amazon

I work in a doctor’s office. I bought this to check my temperature before work every morning in light of the recent pandemic. Would never register above 97.3; however, when I rechecked at the office one day my temperature was approaching 100. I received a refund (from Amazon not manufacturer) for the item, and I realize that sometimes things break. The reason for the negative review is the manufacturer’s response to my refund request. Their response “ It's impossible for this device can never register above 97.3. But we hope to know if you had used it correctly by following the instruction. How about reload the batteries” The response continued with angry veiled references about Amazon for refunding my money. Great grammar, huh? But I must be too stupid to put in batteries correctly. I emailed the company again with the above pictures to show that the batteries had been installed correctly otherwise the display would not light up with the temperature reading. Still waiting for response. . .
