I have the Oliso and if I had to replace it ... it would only be with another Oliso.
I love the 30 minute shut off
I love the quick re-heat time and the fact that once it's on, it stays hot
I love the 12' cord
I love the slick surface that I rarely have to clean, and when I do it's only with a damp cloth
I love the weight, it's not "light", it's good solid heavyish iron (I like them heavier as I feel the weight helps to get a better press for good flat seams)
I usually turn the feet off because I like to let my iron sit on a block/seam for a while and instead of holding the iron, I'll grab another block and open it up to get ready to press ... assembly line ironing. I'll turn the feet on when I'm ironing yardage or clothing.
My only complaint is that because I leave the feet off 90% of the time, every now and then the front foot will "drop" slightly and if I'm sliding the iron the tip of the foot will catch an edge of the fabric. To fix it though is easy ... I turn the feet on, let them drop completely, then turn the feet off again and they recess completely back up into the iron where they belong. It happens after about every 8 hours of usage so it's not a big deal.
I don't use steam so I can't say one way or another about the steam function of the iron.
