Working fine. However the build quality is not very good. ### ⭐⭐⭐⭐⭐ Value abule money *by K***R on 14 July 2025* The product in question presents a commendable quality; however, I must express my dissatisfaction regarding the initial confusion experienced with the F1, F2, F3, and F4 heating display unit temperature settings. It is imperative for users to have a clear understanding of these settings to ensure optimal performance and safety. The lack of straightforward instructions or intuitive design may lead to frustration, particularly for first-time users. It would be beneficial for the manufacturer to provide comprehensive guidance or an instructional manual to alleviate such confusion and enhance user experience.(Very nice product) ## Frequently Bought Together - Real Instruments Digital LED Display Temperature & Humidity Controller With Thermostat Control Switch NTC Sensor Probe Thermostat Adjustable Dual Display Thermometer For Egg Incubator (STC-3028) - Electronic Spices 12v Brushless 3Inch DC Cooling Fan for Pc Case,CPU Cooler, 2pcs, Black (80X80) mm - xcluma 24V 12 LED With Adapter Color Changing Ultrasonic Mist Maker Fogger for Water Fountain Incubators Air Humidifier --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/409156564-real-instruments-digital-led-display-temperature-and-humidity-controller-thermostat](https://www.desertcart.pl/products/409156564-real-instruments-digital-led-display-temperature-and-humidity-controller-thermostat) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
