Product review (4 stars): OK for the price
At first I was a little disappointed in finding that the temperature measurement was 2 degrees high. I expected better. I went to the Acurite website and found that the accuracy specification for the device was +/- 2 degrees thru the temperature range of 32 degrees F to 80 degrees F. So the device did meet its accuracy specification. I expected too much for the price. As an electrical engineer that spent a career designing measurement instruments, I should have recalled that a temperature sensor alone with a measurement accuracy specification better than +/- 5 degrees F would cost more than I paid for this meter.. That's why more accurate meters are calibrated for accuracy and cost more because of the labor cost of calibration. You get what you pay for, and at ten dollars this device meets specifications at a modest price. Hence four stars. Good device for the money if you can accept temperature accuracy of +/- 2 degrees. I note that the manufacturer's specification for humidity accuracy is +/- 10%. Seems reasonable, if you need more accuracy, get out the pocket book.
