As I've said, of the various collection systems out there, Leaf Relief is the best and I recommend it frequently.
However, the FACTS are:
1) debris decomposes and does not blow off the panel as claimed;
2) When it clogs, and it does clog, it will overflow over the lip of the gutter;
3) And the 10 year no-clog warranty is for the INTERIOR of the gutter only, and does not warrant that the gutter protection product won't clog.
I believe in being completely frank with customers. Provided they know what they're buying, I believe Leaf Relief is a fine product offered by an outstanding company . . . both in the U.S. by Alcoa and in Canada by the original inventor, Alu-Rex (where it's called Gutter Clean).
Thanks much for the exchange. Please do feel free to call me.
