Review on Goabroa 12 Pack Mini Small Hygrometer Thermometer: Digital Indoor Humidity Gauge Monitor with Temperature Meter Sensor (℉) – Bulk Pack for Accurate Climate Control by Adam Price

Needed six hygrometers for my humidors. I bought these 12 packs for an additional $5 thinking half would be incorrect if I'm wrong. I put them through the scientific test. 12 hygrometers and a pack of Boveda 69% placed in a tightly sealed Tupperware container. I took two readings from each hygrometer per day for four days. The hygrometers were gently shaken and changed position between each measurement. The results really surprise me. 96 individual measurements were taken, ranging from 66% to 71%. The average value of each hygrometer varied between 69 and 70%. The value of 12 hygrometers was 69.6%. Thus, all hygrometer readings were accurate enough for my purposes. I was surprised. Guess I'll have to buy more Tuppador cigars and cigarettes to use all those hygrometers!
