Product review (2 stars): Don't expect the claimed temperature accuracy.
I'm guessing that most folks who purchased this weather station never checked the temperature readings against a known accurate thermometer like I did. All thermistor-based thermometers suffer from a non-linear response curve and this unit is no exception. It was impossible to adjust the readings so that they were consistent with the actual outside temperatures. The inaccuracy was about + or - 3 deg F, which exceeds what the manufacturer claims by a considerable margin. For example, in the afternoon the actual (using 2 different Hg thermometers of known accuracy) outdoors temperature would be 35-deg F while the unit would report 38-deg F. In the morning, with an actual temperature of 29-deg F, the unit would report 26-deg F. No amount of compensation adjustment could fix this.
The setup of the main unit was daunting to say the least. This was due to the poor documentation supplied as well as the convoluted non-intuitive setup routine, which involves multiple button presses and entries. Eventually, I figured it out but that doesn't save it from a failure to report the correct outside temperatures - which is the very reason I bought it in the first place.
There are a few 'pros' such as the multicolored back lighting, the substantial transmission distance and the ability to adjust the main unit for the remote unit's temperature readings , but at this price point I expect at least reasonable accuracy.
