It took us about a month, but we finally got the big screen doors working properly out back. These are the larger doors that lead to the #newoldbackyard and little patio we have out there. They have this self-closing mechanism that allows us to set them to self-close automatically. It is pretty great - especially when you live with three little savages that don't EVER close any doors behind themselves. Except, when it turns into a guillotine when one of said kids doesn't open them far enough when they try to sneak out. It *does*, however help incredibly well with keeping the house flies out of the, ahem, house. They remain just flies for the most part now.
