Cen-Tech Infrared Thermometer Model 96451 Died

Battery is OK (tried 3 different 9 volt batteries altogether). The unit is just plain dead, pulling the trigger used to turn it on. I repaired my Dremel tool (broken wire) after finding a youtube video explaining that common problem and how to fix it yourself. In this case, I doubt I will ever see it function again. I have dropped it a few times, but not lately.
