Quality of the vinyl and the print is really nice.  I went with the denim blue color and it turned out really nice.  The 4 stars has more to do with peel and stick wallpaper in general more than this particular product.  This would be much better suited for a single wall rather than a room - trying to get this hung around corners and obstructions without creases in nearly impossible.   If I ever have a choice between this style peel-n- stick and traditional paper I am going the old way every time.
