Don't do it!!! We had leaf guard gutters put on 10 years ago. Approx 6 months after, they were installed wrong and we lost an entire wall in our bedroom. It was a waterfall inside one day when it was raining.
When I called the company, told them what happened, they were completely dismissive and told me to sue them. We replaced the wall ourselves.
Today on the other side of my house, where the gutters were actually installed correctly, the gutters clog worse than the old ones we had. I actually have a picture of a small tree growing out of my leaf guard gutters.
Never clean gutters again, well not with leaf guard. I can go on and on.
