They screen works for me....The North side of my house has a large oak tree that drops tons of oak leafs every Fall. Most of the leafs blow off the screen. Some accumulate on top of the screen. None make it inside the gutter. I blow the leafs from the screen twice a year using a very small nozzle attached to the end of my garden hose. The entire job takes about 15 minutes. I have not had to clean the inside of the gutter for 3 years. There is a small amount of fine sand laying on the bottom of the gutter.
The screen comes in 4 foot long sections, and is easy to install.
