I have used it a few times and am happy so far. I was pressing some bias strips and found myself reflexively pulling my non-ironing hand away from the iron until I realized that unless I press the steam button, this really is a dry iron. By that I mean that with my Rowenta Professional regular iron, I could not use a steam setting and keep my other hand near the tip of the iron without burning my fingers. This is amazingly good. The steam is a burst if the button is pushed, or continual if locked down. Let me tell you, there is steam.
It really pushes steam through the fabric, even thick fabrics. I tested it out on a pair of jeans and was surprised at how the other side looked without pressing. The pillowcases were so fast - everything is faster - that I stacked two at a time and it was fine.
It does take about 7 - 10 minutes to heat, and can be refilled while it's still hot. In the first few days I worried about my decision and wondered if I should have ordered the Rowenta as well and given them side-by-side tests, then I got a grip on myself and let it go.
It's early, but I think this is a good addition to the sewing room. The steam, weight of the iron, ability to hold more water than a portable iron, and genuine difference between dry and steam are all good qualities. I am concerned about leaving it running for hours at a time while sewing, and the instructions do indicate that it should be turned off to cool down after an hour of use.
*Yes, sometimes I press the pillowcases and my more expensive sheets. This helps prevent fraying and wear from the creases along the edge that will eventually "crack" the fibers. Since I'm not a pressed-to-perfection person I have to remind myself that this falls under the category of properly taking care of things and just do it.
