This past winter huge icicles formed on the gutter. When the icicles began to melt water went behind the gutter and dripped on my front porch. Meanwhile my back deck iced over from dripping icicles. I called Leaf Guard with no response. Now it's summer with several severe storms rolling through western Pa. With each storm the gutters are worse - a waterfall cascaded over my front porch during the last storm. I am getting more water in my basement than ever before. There is standing water in my gutter I called Leaf guard today - I'll see if I get a response User's recommendation: Don't Buy.
