I'm in a similar situation, we never know when test day is so I keep a bottle of QF in a small "pocket" I made, just cut off 3-4 inches off an old sock and sew it into the strap of underwear but you MUST keep a heat pack on it while using this method, you can buy heat packs cheap on ebay or wal-mart or CVS. The best part is it looks like your really peeing, you unzip, reach down and unscrew the QF top and pour it in. I modified several pair of underwear like this (wouldn't want to wear the same pair everyday, LOL). BTW I re-heated mine over 200 times like this until it was needed and QF still worked like a champ!..
butch100 Reviewed by butch100 on . I get randomly tested. Will this Whizz Kit work for me? What I'm wanting to know is, if I buy this and just keep it strapped up against my leg each day at work, if I'm pulled for a test, will the pee be warm enough to pass the test? Because if so, I won't mind wearing this around every day to work, lol. It's such a simple job but I work for the State, that's why there are randoms. However, they are few and far between. My friend worked here for 2 years and wasn't tested once, after the initial test. Maybe it can be once every 6 months or so. You Rating: 5
