I have a Kambrooke which I paid about $30 for which beeps at me if I leave it for more than 12 minutes. If I continue to ignore it it switches the heat off. All I need to do is move it and it starts up again. I'm not crazy about it beeping at me. I preferred the one I had before which I bought at a store like your dollar store for $25.00. It didn't beep at me but would switch the heat off it it sat for 10 minutes. Again I only had to move it to have it restart. My iron stays on most of the day at least 4-5 days a week.
