I've ordered from the urine-pimp and I passed my test. It was a non-watched test for Costco.

I htink fake piss is a good idea if you are wiling to shell out the 15 or 20 bucks. You can also get piss from non-smoker friends, but it isn't as convenient and there is the problem of heating it up.

I might buy one of those fake penis things (urinator) if I ever need to take a test where they watch.
