Review on 🌡️ MYPIN TA4-SNR+K Dual Thermocouple Temperature Controller with PID and Digital Display, Dual Type-K Thermocouple by Jared Gopalan

Here you get what you pay for. It works, but if you don't know what you're doing, you're probably going to have a hard time. The instructions are difficult to follow. It has a setpoint limit of 1200f (which wasn't listed in the description). It will show thermocouple readings above that value, but you can't set it to a higher temperature.
