Review on AcuRite 01226M Indoor Humidity Monitor by Scott Chen

I ordered a pair of these about 3 weeks ago. Summary - They show 4 degrees less (Fahrenheit) compared to my home thermostat and my local clock/thermometer. They arrived on time and were well packaged. I like the display, easy to read. The high and low of the day seems to be right. Our temperature is lower at night, and "low" was correct (but 4 degrees lower). After they acclimated to room temperature, I balanced them on my home thermostat. Both showed 4 degrees below zero. I then put them next to my watch/thermometer and they read 4 degrees below zero. The moisture readings between them differed by 2% when they were side by side. It will take time to monitor humidity to see if it is useful. Because of the temperature difference, I give the product 3 stars. I think I can use them because they are consistently 4 degrees lower and I can make adjustments automatically when I look at one of them.
