Thank you for viewing. I've used this for two years. My bird prefers being on the ground, and I no longer need this heater, so I'm selling it. The box is large, so I won't include it. Please save the images here. The main unit (the switch is hard to see, so I've written "on/off" with a marker). The main unit and two metal fittings are the items for sale. Please ask if you have any other questions. The condition has some discoloration from being used outdoors, but it works normally. I've confirmed that it heats up.
