Used for 7 seasons. The light bulb was replaced last year. It still works, but the plug is too big for the new cage, so I'm selling it. Since it's an electrical appliance, I can't guarantee how long it will last, so please consider it as a temporary solution. It might be a good idea to have a spare. The light bulb cover has some peeling on the hook. The thermostat has bite marks from a Java sparrow. Please check the pictures.
