I needed a room thermometer that was incredibly accurate to help us understand how hot/cold it is in different rooms of our house and allow my girlfriend and I to compromise on the temperature: PI was surprised at the amount of research I had to do to find an incredibly accurate and scientifically validated indoor thermometer. Most of them have a large margin of error and lack scientific testing to ensure they work properly, and those that do cost too much. These are Thermco ROCKs. It's the only one I've found for less than $40 that is accurate to +/- 1 degree Celsius that comes with a verified guarantee to back up its accuracy AND it's with large and loaded fonts very easy to read. I also found the minimum and maximum temperatures useful to see how things are in that location during the day and night. Save your time, I did the hard work for you - I bought this pup.
