The thermostat still seems to function appropriately. I try to keep the sole plate cleaned and ever so often you are to empty the tank fully and rinse a few times. Recently when I did that a plastic looking screw fell out of the tank and broke apart. I am not sure what its purpose was and so far the iron is still working.
I am not able to purchase an expensive gravity feed iron, though I would love one; getting eight or nine years out of this iron thus far leads me to consider purchasing another similar iron. There are some other Rowenta irons that I have seen; I have not checked any reviews about those.
I would appreciate feedback or suggestions about good irons that you have used. Feel free to leave a comment on this post.
