Review on 🌡️ Uxcell A11061400Ux0129 Thermocouple Temperature Controller: Advanced Control for Precise Temperature Monitoring by Michael Vargas

I had a death for 6 months and one died. So 33% of them seem to be working fine, it really annoys them having to replace them so often, I have no idea what's broken about them but my PID just says ERR, they don't even move, they just sit in Water and temperature control, no kinks, no breaks. I don't know why they don't last long. They are accurate when they work. Update: August 2014, none work anymore, all have failed. I don't buy them anymore.
