Ya, no warranty lol but I actually like it better this way.
All the humidifiers and heaters lately have digital controls that reset every time the power goes off. Makes it to where you can't use things like a rainbird to control. Plus the power goes out enough here that I can't depend on it to stay set while I'm gone.
Had to find a manual heater for my dog's room, otherwise they would freeze whenever the power flickers and it's -20F out
