While these notebooks are pricier than I would prefer, I still like them to use at work. For the most part they are pretty sturdy. This is the third one I have purchased. The first one I bought lasted a little over a year until I dropped it and the binding in the back tore. The second one I purchased lasted for for over a year until I filled out every page. I particularly like the graph paper versions. My job requires the occasional construction sketch. If you like keeping a dedicated work notebook then these are an excellent choice. If the price was a little cheaper I would have no problem giving them a 5 out of 5.
