I bought a Auber SMD200, Solid State relay, and probes and wired myself. for my fridge smoker. Works great. Auber Instruments was so great. I did a bench test with the setup, calibrated my probes, and then unwired and rewired in my box. I screwed up wired the 220V to the PID relay output. Fried the 12V circuit. I was at the final stage and just wanted to finish the smoker. I called Auber and told them what I did. They said that they would fix the PID for $10 with shipping and it would probably be 3-4 weeks including shipping. I ask what they could do on a new controller. They gave me a nice discount for a new PID shipped overnight, and I still had them fix that fried PID for $10. Now I have a spare for an extra PID to play with.
Excellent Customer service. I would not hesitate to by from them. They are worth the extra $s.
