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

I buy a lot of these, around 40-50 a year. And they've always worked fine, but I've had one where the thermocouple connections didn't work. I have exchanged it for another one that works fine but one out of the box is broken and as I buy them in bulk I often don't use them all at once and now my return period has expired and there is no way to fix that Contacting companies ( Best Rich) and they have no return policy which is listed here on Revain which I think is crap. I will not buy from this company again in the future as they have no way of contacting them.
