I am using the gutter filter "style" product on my home with outstanding results. Take it from someone who knows a thing or two about gutters; this is the best system I have seen yet. But remember, there is no magic bullet for gutters. Regardless of what system you choose to block debris, they all need service. Know this going in and you will be far ahead of the "games".
Hokey hoods are nothing more than black magic. At least with this product, one has a chance to see what is going on up there in the gutter. Best of all, its a lot cheaper than the better advertised products and far more effective.
