It's only 25 cents. It's functional. Saves me the hassle of shopping for hex or grid paper. I don't think I'd be laminating these sheets like the product suggests (if I'm gonna spend money on lamination, I'd buy a full size battlemat). It's not completely editable. The grids themselves can't be edited, only the "back" of the cards. Would have liked it is the actual grids were editable, so you could, say, color grids different colors to signify terrain, walls, etc. Would allow for a neater apearance instead of manually having to color in or draw these elements.

Very enjoyable product that helped me thing of some more interesting ideas and what to do with in my games.
