Worth every penny but install with extreme care and precision.
Up front, the only additional thing I would ask for is a scale cut out to assist with getting all the landforms on the wall to scale on the first try. The box has a smaller representation of a world map, but the scale doesn't give you the proper sense of space you'll need to get this map on the wall in the right proportions. This is critical because the peel and stick adhesive is aggressive and if you misplace a landform, you could peel your latex paint off the wall trying to reposition it. As such, the box map is missing finer details necessary to get all the islands into place. For that we had to go to blowups on Google Earth. So to do this well, you'll need a really access to a well detailed Mercator map (computer) and a long level to keep the continents in the right place relative to the equator. But damn, the product is pretty. The cutouts are precise and perfectly legible. Time will tell if the adhesive works on the wall over the long haul. Despite the higher degree of difficulty than anticipated, it looks freaking fabulous. We are very, very happy with how this turned out.
