I requested a free sample of this product right before it was released not knowing how I would use it. It sat on a shelf in my classroom for a little while until I saw it in an e-mail mounted to a table. I have a table at the front of my high school math classroom and I put it there. Now when my students are working on their collaborative group work, I can call individual or small groups of students up for extra instruction or to ask them to perform a task. It writes smoothly and erases easily so it's great for quick explanations. If I had a classroom of tables instead of desks, I would purchase one for every table so students can share ideas and work collaboratively. [This review was collected as part of a promotion.]
