I'm writing this review to clear up misunderstanding about product as I see a couple.The gist of it is. It will turn purple instantly or within a maximum of 15 seconds.If it does not .Then it's a negative.It will however turn purple anyway if left on many other things for longer than 15 seconds.Summary 15 seconds or less anything more is false results.Hope this Helps

Is what it is

This product will react to female discharge! I tried this on while on my period, no sex of any kind in the amount of time stated on the box and still got reaction due to my period blood. Instructions unclear too, if you let solution sit long enough paper will always turn purple.

Quick delivery

Fort idid it wrong. You have to let the paper dry before you put the other tuff. And it work

Tried this and it actually work.

Directions aren’t extensive, did read twice to make sure there were no mistakes. Tested a sample I knew to be positive, and purple coloring was unmistakeable. Transferring dried sample from clothing might need more than 2-3 drops recommended, but ultimately was successful.

It's ok.
