The iron shows some general signs of wear from use, and has some scratches, spots and debris.  I powered the iron on, and it gets extremely hot.  I added some water into the cap, pushed the end button and steam came out fine.  The selector dial also turns fine.   I'm not sure what the yellow button does, and am not sure if it's working, so the unit is being sold as is or for parts only.  Please see photos for actual condition of item.  Thanks for looking!
