Review on Powerful URBEST JQX 12F General Purpose Automatic: High Performance at Your Fingertips! by John Destruction

I have two 400x400 heated platform printers. This relay worked like a charm and gives me the comfort of knowing that unlike solid state relays it works. They will fail in the open position, completely cutting off power to the heater. Although I've given more than one failure. The contacts clicking, which is annoying to others, lets me know it's working and lets me see the range it's holding temperature without the need for a multimeter.
