I received this sample from 3M to evaluate.  It was amazing!  As a volunteer fundraiser for charities in my area, it was the perfect design for sitting on a table anywhere we held our meetings to brainstorm ideas, drew vertical lines to make a monthly calendar/schedule for tasks/events, and list agenda items for upcoming meetings.  It is portable, lightweight and so much better than the heavier chart pad holders that we used to have at work.  We will definitely be using these in our future meetings.
