QOSEREN Panel Heater Purchased for around 2000 yen. I kept it at home because the size didn't fit. Panel Heater, Essential for Cold Winter Days: Panel heaters are warming devices that function like underfloor heating for humans. They warm your stomach from the floor, raising your body temperature and aiding digestion after meals. Variable Temperature Heat Mat: By turning the dial, you can set your desired temperature within a range of the ambient temperature to 45°C using self-temperature control. This product is attractive because you can freely adjust the temperature according to the type and condition of the reptile. PS: Since there is no temperature display function, we recommend using it with a thermometer. The range of ambient temperature to 45°C means that if the ambient temperature is 0°C, the panel heater can reach a temperature of 45°C, but if the ambient temperature is 20°C, the panel heater can only reach a temperature of 15°C. Convenient to Install Panel Heater: It has a thin, sheet-like shape, making it lightweight and easy to handle. Since it is basically used outside the cage, there is no need to secure a cord hole or installation location, and there is no worry that the reptile will touch it directly and get burned. Use a Panel Heater to Create a Temperature Gradient: To create a temperature gradient, you can place the panel heater outside the cage. By placing it on the bottom of the cage for about 1/2 to 1/3 of the area, you can also create a temperature gradient. Multi-Range Usable Reptile Heater: This is a panel heater to be used under the cage. In addition to reptiles, it also supports amphibians, small animals, and birds.
