I have been using a travel iron, & love it, but I have noticed, when I turn it to the off position, it does all go cold, so I know it stays on a bit. So, I have just gotten into the habit of turning it off, then unplugging it. I also check my studio, one last time, before I go to bed at night. It's the bedroom right across from ours, so no biggie, but makes me feel better doing it, just in case.... Glad no one else has had any iron problems like these!...
