Thanks for the information. I have two Rowenta's; one in my laundry room (the most expersive) and one in my sewing room which I bought on sale at Bed, Bath and Beyone plus a 20% coupon. I have never had a problem, but I do unplug the one in the laundry room all the time. I have been turning off the one in the sewing room, but I am quilty of leaving it plugged in. Thanks to your message, I will in the future unplug that one also. No matter what the brand, I think it would be a good idea to disconnect the cord from the outlet.
