Don't know why but I can't see the pic from my PC, but I can see them from my phone?? Odd huh!
So you can see in Batch 1, they are nice and obviously pos compared to the neg tests and the lines are quite thick.
Batch 2 are not so obvious, more of a fade in/out effect, and the lines are thinner.
The ebay ones are nice and dark, but also have the fade in/out.
