So - I've put the Test C in my orderlist first.
I guess, this is atleast an indicator, that the kit with the "1" is the Test.
That strengthened my belief that the vials with the copper ring is primo and the other one is test.
Well I've came home today, after putting a vial of both kits into my fridge. The one, that is supposedly test (Nr. 1) crashed, while the other one is still clear.
Isn't the Primo supposed to crash first? Now I don't know what to believe.
I guess its either Jano or I do a mix, since its a decent primo/test ratio anyway
