I have not tested this. This incubator is being sold AS IS. Its beautiful with a little work and restoration this would be a great working incubator and art piece. I can not find a plug in for this. I think it needs to be wired for one because it looks as if it was hooked up to a 2nd 'Mother' incubator. There is a wire that I can see that had been snipped about 1/2 up on the left side in a little hole. It is missing the 2 trays in the top and one in the bottom. I also do not have any of the wire baskets that originally came with it. I am located in Boise Idaho and am ONLY offering local pick up.
