I got their "never fail" kit, and it failed miserably. Even after a week of abstaining, I still tested positive. Their products are a complete waste of time and money, and they do NOTHING!! Their support is a joke, their products are nothing more than junk. I am now in the position of having to re-take a test after several more weeks, hopefully I will pass then, but I will NEVER EVER use passyourdrugtest.com again.
