I have a rowenta and oliso, both leak. Conclusion irons leak. I still ad water but sometimes it can be a headache if it leaks. My rowenta likes to choose when it leaks, sometimes it does not. I got an oliso just for stean to use my rowenta as a dry iron since the heat of it can't be beat and it heats up super fast way faster than the oliso even in auto shutoff it heats super fast. Oliso brand new leaked so what is a girl to do. It leaks less than my rowenta so it will be my steam iron
