Break in: 2
The price point was great, I've used the Light 2004 80/20's before for recording and they've been consistent in the past - not this time. I'm not sure what changed but in a climate controlled recording room, these strings will not stay in tune even after an initial stretch and three days of break in time. They're consistently inconsistent and lose about 1/4 of a step from A440 each time I pick it up. I can't record with them and I wouldn't gig with them but I'm guessing they're fine for practicing or as an inexpensive string for teaching or emergency backup.
