I had gutters installed for the entire house and the gutter guard just in the back. The system works great! My only mistake was that I did not install the guard in the front of my house and guess what happened? I just called up the gutter guys and they were more than happy to come back and install the guard for the front. They came and did it the same week I called! My overall opinion, although a bit pricey, but comparable to their competition, is that this product is a home run! I never have to get on the second story of my roof again. My gutters have not clogged since the installation. The staff and crew are great and I would recommend this product to anyone who asks me about it.
