Product review (1 stars): I was also disappointed to find when I read the instructions the accuracy ...
My Ambient Weather Thermometer was shipped in a bubble wrap envelope. After I read the directions and inserted the batteries, making sure the polarity was correct, there was never any display on the screen. I checked the bubble wrap which was placed in the box at the factory when the thermometer was packaged and found about 80% off the bubbles had been ruptured. Since none of the bubbles in the shipping envelope were punctured I assume there was excess weight applied to the device at some point prior to shipping; enough weight to damage the thermometer. I was also disappointed to find when I read the instructions the accuracy of the temperature was plus or minis 4 degrees; a bit sloppy for what I intended to do with it.
