I've never guessed rain guard gutters would have worked. I never understood how the water would run inside the gutter but not the debri.
Using my common sense I figured pine needles at least would make it inside with the water. But then I wondered, "hmmmm how would you clean it out?" That's when I decided to read the reviews.
I don't have these useless gutters but figured I would offer some potential advice for everyone who had been robbed by this company and report them to the Better Business Bureau and see what they can do for you or start a class action lawsuit. You deserve your money back, you worked hard for it!
