We are more standardized than we think! I also trim out the logoHaha, me too for the only one that I have used, which is on my analyzer case, although the label needed shortening anyway.
Right now I have them only on my jetfins, since there are so many around and I want to be sure which are my ones. I may add them to the canister of my next light for the same reason.
EDIT: Also, never had a GUE T-Shirt on me out of my apartment (except maybe during GUE projects or classes). But that it isn't true only for GUE... I just don't like logo-clothes: the same applies to my red cross clothes, Erasmus student network clothes, etc.
