Even better than expected. It has all kinds of great features and it does work perfectly. The issue is that there are no instructions. None on amazon, and none with the unit. After spending some time searching other thermostats on amazon that looked the same i was able to locate instructions from a different seller. Other than that, I am Pleased. In case anyone's looking here they are. ### ⭐⭐⭐⭐ Max temp? *by M***E on January 21, 2024* This listing says the temp controller is good for 500C but the product itself says its only rated to 120CBe wary ## Frequently Bought Together - Temperature Controller 12V 500C Dc 12V Led Digital Thermostat Electronic W3230 Led Digital Temperature Controller Thermostat Switch Sensor Meter(Dc12V) (24V red and Blue Display) - Fielect Gear Motor DC 6V 50 RPM High Torque Electric Motor Micro Speed Reduction Geared Motor Eccentric Output Shaft for Car Robot Model DIY Engine - Twidec/6Pcs Rocker Switch 3 Pins 2 Position ON/Off AC 6A/125V 10A/250V SPST Red LED Light Illuminated Boat Rocker Switch Toggle KCD1-5-101N-R --- ## 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.ae/products/726779869-temperature-controller-12v-500c-dc-12v-led-digital-thermostat-electronic](https://www.desertcart.ae/products/726779869-temperature-controller-12v-500c-dc-12v-led-digital-thermostat-electronic) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-13*
