I was sent a free sample of the 3M Post-it Super Sticky Dry Erase Surface, 3ft x 2ft, in exchange for a review of the product.

That said, I found it very easy to "install".  I chose to cut the sheet into smaller sections and apply to a school table top for mini dry erase areas for students to write.  It erased easily and didn't "ghost" or leave any stains behind from the dry erase marker.  The students loved having the dry erase surface available at any time instead of having to get a board to write on.  It also made it very easy to use during small group lessons.  I didn't have to waste time passing out boards and then picking them back up.  I think this product has a variety of possible uses and I could see myself purchasing it to use again in the future.
