Just a quick tool tip today. I discovered this gadget when our family rented a house in Hawaii several years ago. This little door stop kept all the doors from slamming shut all the time when a breeze came through. Also handy for keeping the door open when you are bringing in armloads of groceries. It's like having your own doorman. That you don't have to tip! I love the one I installed at home.
