Over the years I've purchased a lot of irons which later burned out because of the volume of pressing involved with the amount of sewing I do for my business. Throughout the years, as my knowledge in sewing expanded, I found the irons I was purchasing were the wrong kind/type.
My most recent disappointment with an iron was the Oliso. The first year I had the iron, it started leaking. I would have to keep a hand towel on the ironing board to catch the leaking water so it would not damage the fabric. Two years later, my Oliso iron had burned out completely. When I tried using it one day, I filled it with water and the water ran right through the iron onto my ironing board.
