Product review (5 stars): Works great!
Works great! Got here in a day!! I just pulled the little tab and was able to walk around my house to determine where it was driest. Temperature in the rooms works rather fast as well and is accurate according to my digital thermostat for the house. Cannot believe how easy they are to read too. Seems to be very well made too. I will be getting another one to monitor my down stairs as well as one for my parents house. These things are great and unbelievable for the price!
