Query: disappointed...

I bought the Rowenta Effective DX 1700 from Bed Bath & Beyond (they had an offer with $10 off), about an year ago. At first, it seemed to work very well, and I loved the way the ironing plate sled over the clothes. But, in less than 6 months, the iron heated up only immediately after plugged in, and maintained a much lower temperature shortly thereafter; in addition to this, using it mostly for cotton, there is no steam whatsoever coming out.... Very disappointed...
