Product review (5 stars): High & Low Humidity is not accurate
Product is economical. Current temp & humidity is withing range for the price point. However 24 hour humidity range is useless. I purchased around 40 meters for use in vacant properties to monitor temp & humidity. The high reading for humidity (24 hr) is off the charts incorrect. Actually need to replace all units with a more reliable product such as Acu-Rite
