I had a series of the older models. I now have the yellow and it has been working now for a few months. So far no problems. However, I would not replace it with an expensive one. I do like the legs that jump up and down.
If you do get one but do as the other post suggest, keep box and receipts and get it exchanged and go directly to the factory if necessary. I would be cautious buying it from their booth at a quilt show unless the booth people are from the company. There are groups who sell the iron who are not from the company and some are difficult to deal wth if you have a problem and didn't buy directly from them.
The best advice on buying an iron is the one that says get the cheaper ones and toss when problems.
