I love that you can store them safely! That they are easy for me (and others)to find when we need one at my house without having someone else come with us each time! You don't lose anything because once there is an empty box available then its yours until another person gets their hands into those boxes again - great!! No issues so far but would like more information about insurance coverage if needed; also any special rules regarding what happens after all documents/boxes inside of this product reach capacity limit set by manufacturer?
