Also suitable for old persona.

I still have the old persona (the white big fridge :-)
I bought the sticks I the computer to prevent and to become pregnant use.
As to get pregnant, I used him for the first child and my fingers were expired, I bought this here ... What can I say. Ie 1 cycle used 8 sticks and now the rest of the pack is in the closet and goes stale until you get the next job, because I'm pregnant again. I can therefore accurately determine ovulation and become pregnant or use to prevent it. Very reliable and as we have said can also be used for the Ancients Persona computer. My I then bought in the 90's if that someone should help you decide.
