Addendum: 12/15/2014
Must my statement into perspective a bit. One sees the light and easily carried by the black area. Is really not annoying and because the stickers come in 2-pack, you could stick the second nor the first. I will not do because it does not bother me. Sorry for too rapid Erstaussage.
And since the delivery takes a long time, one probably better two times order, if you want to mask off two controllers opaque. Saves time.
