I have one iron that turns off after a few minutes which works well for me. Then when I'm done for the day, I manually shut it off. But, I also have a small iron I keep by my sewing machine that's great for piecing. I leave it on while I'm working then turn it off when I'm going to be away from it for a while. To remind me that it's on, I put a hair scrunchy on my wrist as a reminder. I had to do that when I left it on overnight ( :shock:
hope this helps !!
