Snoop's Take

The Extech 445713 Big Digit Indoor/Outdoor Hygro-Thermometer is designed to monitor temperature and humidity levels, making it suitable for various environments, including home gardening and reptile care. However, consumer feedback indicates significant concerns regarding its reliability, with remarks such as, "The thermometer is trash, you want a digital one," highlighting a preference for digital alternatives over analog readings. Additionally, users have noted discrepancies in humidity measurements, stating that, "Humidity very inaccurate I have 6 sensors and all of them are more than 10% lower in RH readings," which raises questions about the device's accuracy and precision. Given the overall sentiment expressed in user reviews, this product is not recommended for those seeking reliable temperature and humidity monitoring solutions. Users are advised to consider digital hygrometers for more accurate results and dependable performance, especially in critical applications such as reptile habitats or sensitive agricultural settings.
