I had been cleaning out my gutters for years because everyone I knew that had gutter guards said they didn't work. As I'm not getting any younger, and climbing ladders is no longer safe, I decided to try out Master Shield because the seemed to have a better design. I was skeptical that any gutter guards could be this good. I was wrong and Master Shield was right. They have been exceptional. Now I stay safe on the ground and my gutters stay clean.
