gaming paper?

I have been seeing a new product called Gaming Paper which is a thin, paper version of a battle-mat used for gaming.  The paper is about 2.5 feet wise by 12 feet long.  it's supposedly reusable and disposable.  Has anyone tried using this and what's your review?  I have 2 battlemats, but age, and old marker stains on it are making it less desirable to be used anymore.

I've heard of this thing, like a dry erase mat with hexagons on it... something like that maybe?
