Review on ETC-JLD612-A Temperature Controller With Dual Display And PID Control By Lightobject by Luis Estrella

I'm using this for a sous vide setup. It worked just fine for a few months, but now it randomly stops working. It will cycle through turning the heater on/off a few times, but then it will just stop heating altogether. The auto-tuning stops and the temperature drops and drops and drops.until I manually turn the auto-tune back on again.then it fails.etc etc etc. Very frustrating.
