I would honestly say it was 30-50% brighter. If you look back on posts about it, you will see me saying it’s wasn’t worth it and the only benefit was the color, but people said they get brighter over a few days and they were correct. I wouldn’t pay the full Price To buy them new TBH. I think they are worth it used, but I wouldn’t buy it for the full price. You can take that as in trying to sell them or you can take that as my feelings haha. I’m being 100% honest.
