Just had this product installed 11/16/14. We had after a minor snow storm < 3 inches that covered the roof gutters and leaf filter screens.
Later that evening and over the last few days as the snow began to melt on the roof, the water was not flowing into the gutters but over the top of the gutter system. In my opinion if water is steadily dripping / pouring over the gutters then the system is failing to do what it supposed to do. Water is not going into the gutters as it melts.
Product fails to deliver as promised.
