I use several of these at once -- one (color coded) for each project. It's easy to grab the right notebook and take it into a meeting or check what is on the to do list or add contemporaneeous notes. The size is perfect. It fits into a purse or briefcase and stays right next to the iPad. I found it best to only write on one side of a sheet since I tend to highlight or use permanent markers. But for regular writing both sides of the paper can be effetively utilized. One of my "go to" paper items.
I love these notebooks and so does my son. We use them for everyday business note taking and they work great. They are bigger than the small ones but you can still easily fit them in your purse or bag. The pages are perforated so they give you a nice clean edge. The pages are a bright white and are wide enough to take extensive notes and not run out of room. I use these for home use too to write down a recipe or an email address when I need it. They are very convenient to use for everyday use. We love them and I buy them often.
