Since there are so many reports about Rowenta, obviously there is a problem. If you have had a fire or overheating problem please report it to the Consumer Product Safety. Safety is the issue and nothing will be done unless it is forced upon the company. Anecdotal information is not enough. If you have had an issue with Rowenta, go online to the Consumer Product Safety and make a report. "I did not find any reports of Rowenta irons having problems." (recalls)
It doesn't seem to be a specific model, but an overall engineering problem. Call the company if you are having problems with your iron. Mention the quilting board. I think they will get the idea that their best prospects for new irons are very unhappy with the quality of this product. Do you belong to other forums? of course you do. Ask about other peoples' experiences with the iron. Let's get the word out.
I loved my Rowenta iron. I never had an iron that performed as well. Unfortunately, it is not a safe product. I don't want anyone to be injured or lose their home to fire.
