I am a school social worker and 3M offered this product to our school as a sample.  It was and has been used well by our staff.  As a social worker, office space is at a premium and we are forced to create "mobile" offices.  This product came in handy in order for me to create a makeshift dry erase board for use during my social skills groups with students.  The ease with which I was able to hang this on the wall in my office was a blessing.  No tools required!  Sadly, it was removed over the summer as they decided to paint office walls.  Thank you for this great product!  I would purchase for home and school regardless of the price as it is worth it!  Highly recommend this if you work in the schools!
