Bests & Worsts Reviews from Amazon

I just bought 2 of these 00325W units . Neither would display an odd fahrenheit temperature reading. For example, while the device would display 66,68,70,72 degrees it would not display 67,69,71,73 degrees. It just moves in 2 degree increments. I contacted the manufacturer twice. The first time by phone they said the device was defective. The second time by email they indicated that the device was made to measure centigrade degrees, and that its software was the problem in not displaying the odd digits in fahrenheit. I've owned both cheap and expensive measuring devices previously, but even the cheapest could display all the fahrenheit digits, which this unit cannot. Unlike the temperature readings, the humidity readings do display all digits.
