Product review (4 stars): Great for Baby's Room!
I'm only giving this a 4 star because it seems like whenever I change the batteries it still blinks red...which is the indicator for a dying battery. Nonetheless, it still reads the temp accurately to me. I use it to see the temp/humidity in my daughters room....perfect use for that! I keep the main reader on my night stand, and check on the nurseries readings through the night. This is essential during winter months for colds/croup!
