I just wanted to share this comparison of same urine on the first response vs. an 88¢ cheapie. I am currently on day 12 of testing out the trigger shot, so this is not a true positive.

The cheapie shows a very faint line, and took longer to get darker. This picture is after 4 minutes on the cheapie, and a little after the 10 minute mark the line is darker and more noticeable.

It's faint still, but there is no denying and no need for squinting to see the second line on the first response!
