I have a job where I'm outside in all kinds of weather.  I also have to carry paperwork around with me, pens, etc.  This clipboard allows me to keep papers, a few pens and even a Kindle Fire relatively safe from the elements.  The hinge is strong.  The cover stays perfectly lined up as long as you don't give it too many bumps and bruises, the spring loaded locking mechanism that keeps the lid closed works well and you have an instant "work table" anytime you need it.
