As a firefighter this was one of the first things we purchased after we moved into our 2 story house. There is simply no reason not to invest in something so cheap that can save your life. Lord willing you will not need this device but you do not want to be in the position of needing it and not having it. I recommend at least 1 in the upstairs of your housing unit in a place that is easy to get to. This ladder is well made and easy to deploy if necessary so that even kids can do it if left at home and the worst happens. I would certainly recommend this product to others.
