We paid Chicago Gutterglove LLC to put their product on our gutters. They did the work in late October, so, we haven't really had enough winter weather to see how well they work. Their pricing was good. They didn't show up when they were supposed to, so, we rescheduled, and they didn't show up again. When they finally did make it out to us, there were questions about the gutter sizes being right. They had to re-measure and it just seemed as though a lot of time was wasted because they didn't do a very good assessment of the job before committing to it.
