Billy, our gone to the moon and back still cannot perfect a better guttering system. Billy, that screen is a band aid to say the least. I have seen that screen so packed with debris that the gutter won't even drain water.
Many of my customers are taking theirs down completely; where and only if there is not a flower bed or erosion problems in not haveing one there.
I am seeing more and more of that "rain handler" around, tech looks and works nice. Just do not have any first hand info on it.
