Product review (1 stars): Wildly inaccurate outdoor temperature readings from this piece of junk!
I have never had a thermometer as inaccurate as this piece of junk. Out of the box it was 12 degrees F off compared to a reference bulb thermometer. I calibrated it at 75 degrees F and found it was only accurate from 71 to 79 degrees. When I put the remote reader outside in the shade with 100 degree F, (bulb thermometer reading which also matched Accuweather temp), it read 110 degrees F. I tried re-calibrating it at various temperatures and found it wildly inaccurate outside of a plus or minus 5 degree range from the calibrated temperature. Don't waste your money on this worthless piece of junk! This was my third attempt, (third manufacturer), at replacing another brand of wireless digital thermometer that served me well for years and, all were inaccurate. I had hoped that this one would work better because you can "calibrate" it. What a cruel joke!
 I wonder if anyone still makes a reliable digital wireless thermometer anymore, or is it all just junk nowadays like a lot of electronics made in China?
