So after testing I have come to the conclusion that I like Instant Shine 2.0 (mx288?) best out of the 2.
Not only does it last longer, it diffuses better. I noticed people were zooming in, lingering around, sometimes I would be talking to someone, they’d walk away do whatever they had to do, but then come back and conversate some more.
2.1 (mx289?) wasnt too bad either, but it was closer to the original imo and a bit more subtle to both 2.0 AND the original, whereas 2.0 was much more blunt.
2.0 also has a better (good) scent for whatever reason.
