No one mentioned Gutter Helmet? http://www.gutterhelmet.com/
Conceptually, this is the only product I imagine working. I don't have
any deciduous trees tall enough to get leaves in my gutters, but if I
did, I'd install gutter helmet. The problem with screens is they get
clogged.
LOL The problem with Gutter Helmet is that it's more of a gimmick than
a solution.
