I appreciate all the feedback...

Can someone recommend a good place to order these integrity strips? What if I ordered directly from urineluck.com? Would there still be the need to perform the integrity check?

I've used QF successfully 3-4 times with no problems. But some of the new info is a bit disheartening. I'm sure it's just some headshops that sell that shit when it's expired or don't store correctly or some shit. At least I hope that's the problem and not a QA/QC issue at the manufacturing level.
