I would not purchase Leaf Filter system again.  In 3 years it has done a good job of keeping debris out of the gutters, but the black stripes that form on the front of the gutter between every 4' section of gutter guard are unacceptable!  The tech support rep for Leaf Filter said to just get up on a 2 story ladder and wash the stain off each year if it bothers me.  Totally defeats main objective of the system--keep me off of a ladder!!
