I think it was relatively easy to use for this application. The work is tedious, because the letters have to be transferred and frequently need to be teased off with a pick (like a dentist would use). I do not have a lot of experience with the machine. My wife and girls are the main users. I am going to try it with some other pedals that need labeling. My concern is that the stickers may not weather well; hence, my question above.
