I called for a estimate for my home and John came out and explained the product, measured the gutters, and gave me a cost. He called today and ask if I had made a decision on buying the product. When I told him I had done additional research and decided not to buy, he told me he wished I had done the research before he came. My idea of looking at the actual product and getting all the information from the salesman available, then fact checking must be a new one.
