Many thanks to Post-it for sending me this sample product. I'm now totally dependent on it for brainstorming and generating new story ideas. The size is perfect and can be seen from the back of a classroom. I think a good addition in future would be to add a tab in back so that it could stand on it's own on a table in case you don't have an easel handy. Other than that, I had no problem using the product pretty much anywhere. I used sharpie fine point markers, which worked well also. [This review was collected as part of a promotion.]
