The I item work fine. The temperature is fully cover with dust due to the old age and the seller photo is accurately show the condition of item. I use the circuit board mix with my old housing to make it better appearance. I did the clean up with electronic cleaner to the temperature sensor that fully cover with dust. The seller almost send me every thing except 1 piece that I red circle in the photo. I would give a plus value score for that. When I ask the seller about it, no response back.
