I've been interested in the Q2 in blue for a while but I keep seeing it looking really different in various lights, does it really change that much?

In the pics on their site I can see a bunch of dots where the white goes into the blue a little bit, presumably to help the two colours stick together. I don't see them in your pic, your's looks super clean, is it something they've fixed?

Are these PBTfans Klein?

It makes more sense to me to have blues on locks rather than enter or delete.
