It even works!! I had it plugged in all night, it held good temp. Waiting on my new wicks and thermometers from Cutler Supply, so that I can test out the humidity. The tray is in great shape and hold water, just needed some cleaning. I took it all apart and cleaned everything the best that I could. I don't have the bottle and they want almost $14.00 for one. Does anyone know if any bottle will do or do I have to have that one with the nut on it?
