Product review (5 stars): Very satisfied
Had this nearly a year now and am happy with it. Still on the original batteries. When I first put the batteries in and left them side by side, the readings never quite matched, but I don't need weather station accuracy nor do I expect it for $20. I live in a hot dry climate and use a swamp cooler for cooling, so all I really wanted was to know when it was too humid outside to be effective or when it was cooler outside and all I needed was the fan. (Just checked the min/maxes for the last 11 months - max temp 111, max humidity 91%, min temp 27 and min humidity 1%.) Maybe some folks have gotten defective units, but mine has worked just fine.
