This stuff is fantastic.  Wish it would have been for sale when I was in the classroom.  The stuff I put up was inadequate and over time, it wore through quickly with daily use.  This is wonderful.  Right now I am trying it out on my desktop so I don't have to constantly look for sticky notes.  This was given to me by 3M.  I recommend this product to anyone for their classroom or for their desktop. [This review was collected as part of a promotion.]
