I have an Oliso too. I don't use steam either, just a spray bottle. So I can't comment on that.
However, I have LOTS of problems with the front foot (at the pointy nose end) of the iron. I doesn't retract all the way. It snags the fabric and crumples it under the iron. It irons in more wrinkles than it irons out. I've had it for a little over a year, & I would not buy another one.
I have replaced it with a Panasonic cordless, and a small Dritz Mighty Steam iron. I like them both.
