This iron has a large amount of holes to let steam through and the results are undeniable. I tried this iron on a big basket of laundry and I finished it twice as fast as my old iron. The large water tank lasted the entire time. There are no heat settings because this iron figures it out on its own. Like magic! I even tried using it as a steamer and that worked as well. I will definitely be checking out this brand in all future purchases.
