Great product and does what it is suppose to do.  I've got the griddle w/ the hood.  I needed the screens to block the wind we have.  The screens work great.  I never have to worry about the flame going out.
But, I wish there were screens to fit the models with the hood.  I still use them.  The hood does not close completely.  But between cooking inside or using my - I will use my griddle. Small price to pay to keep the flame on.
