Not really sure if they're the same ones. This is in Sydney btw.
Blue with white specks with "US" logo on them, indented edging, slightly crumbly (ie, you bite into it and it breaks into big (ha!) chunks)
Had half since I wasn't sure what the effect will be (was told EZ test turned purple, I have my doubts on that). Lasted around 2 hours tops, and I mean tops. Had the other half 2 hours later because I didn't feel much, and it again it was very very mild.
Majorly disappointed as I've "abstained" (heh) from the stuff for the last 3 months, so I thought I'd feel SOMETHING.
Enjoy
