Product review (5 stars): Very handy; AA not AAA batteries
Love these little guys. Ordered two at $17.50 a while ago, and just grabbed two more for only $14.99. They take 1 AA battery (much more cost effective than AAAs). I'd prefer if the temperature, rather than the humidity, was the larger / more readable number; but they work great. No more arguing with the wife over how cold or hot the house 'feels'. Just read the number and live in reality :-)
