DR Strings NMCE-9 Lite (Multi Color)

These strings are very interesting to play with the Rocksmith game (the string colors match the game), but also for learners general use, and they look cool! But that is it.
Unfortunately, the colors wear out quickly.
And I have the impression that the sound is not very alive, compared to regular nickel wound strings. They are trickier to tune and it seems not holding long, need to retuning frequently.
