I live in a very windy area so before I got my wind screen I had a hard time getting consistent even heat on the griddle. When it was especially windy it was difficult to keep the griddle areas at the temperatures I wanted. 

Once I installed the wind screens I can get higher and more even heating across the entire griddle. It’s taken some time to re-learn how to use my griddle but I can now cook with out fear of the uneven heating I experienced before installing my wind screens.
