Great product. Could be very useful, however, i tend to be very hard on my work materials. I was using this product daily for work notes and keeping track of daily events. It spend half the day being yanked out of and shoved back into a pocket last summer. For the most part it help up, but the edges started fraying and pages fell out. Its very useful, but if you're hard on your gear, i would choose something a bit sturdier like the hardback notebooks or the thicker moleskines. I have a set of the other moleskines and i love them.
