Pound World/LAND tests

[Queen Bee.]

Has anyone used the pound world/land tests (I cant remember which i got them from) but they are in a pink and purple box and you get two boxes for 1£, do you know if they are any good? are they bad for false readings?

Thanks for any help!

ALSO:
When I used one the white part of the test would turn pink/red with dye the line would show but the dye would float around the white and not go away til it dried is that normal?

I used when I got my bfp with my daughter.

I've used these and they've been fine apart from one of them which left me with an evap, but that was just one out of about a hundred lol, and yeah the pink doesn't really fade till they dry, it's normal it stays about 5-10 mins x
