I am really not satisfied with Chicago Gutterglove LLC. I had them install the screen type gutter gloves over my gutters about two years ago. I really am not satisfied with how they build up with ice during the winter. The product itself just does not work with snow and we have a lot of that here. My song got the smooth gutter gloves installed on his gutters and he says they work fine. I think the smooth ones may work better but for now I really don't like that the gutters get buildup of that ice in winter. For this I would not recommend Chicago Gutterglove LLC. or the screen type gloves.
