I'm not really interested in the band, which I didn't even know was a thing until now, but suddenly I'm feeling a bit ripped off that I didn't get one along with my I.I.
As for the sunglasses, there seems to be a false perception among some that they came with the bike, I assume because it appeared in some promotional material. I was neither told that I'd get a pair of glasses with the bike nor did I expect them (and FTR I didn't get any).
Not that it wouldn't be cool if they were included. Much more so than a band.
