I love the fact that my Macbook and iPhone can both take advantage of this feature, and this kit is excellent except for One Thing. Why not label the darn plugs? I write this only in hope that they will improve this in the future. Even a letter code would help. Korea and Europe are so similar that you cannot tell them apart. There are slight thickness differences, but it takes some effort to differentiate them. Why not emboss the countries or a letter code that corresponds to the images on the back of the box?
