The dry erase surface seems about as good as a standard white board (writing and erasing), and the back is super sticky as promised.  I tested this on a standard surface, and the adhesive and resilience of the material made it hard to remove.  And once I did (it kept flipping back onto the surface and re-sticking), it also stuck right back in a different position.  I want to put one on my fridge to organize lists, and I think I can; my main concern was my toddler destroying it, but with how thin it is, I don't think he'd be able to remove it.  Again, the material seems solid, but I can't say much about the durability of the white board surface for writing/erasing yet, nor about how well it can stick to an uneven surface.
I received this item for free with the expectation of a review.
