The clips on these gutter guards need to be compatible with your gutters. I have aluminum gutters with boxed rims, so the clips didn't work. The clips work on flat, folded rims. I ended up flattening the gutter, and tucking them under the shingles and letting the edge sit on the gutter rim. When I saw them from the ground, I could see how they were a wavy edge. When I'm on the 2nd floor and looking over the roof on my low roof, the gutters look crude. Also, if you end up cutting these guards to fit your roof, you will need to avoid a single hinge attachment. In spring I plan on removing these eyesores and going with white vinyl guards.
