The whizzinator is a good product because it takes much of the worry out of keeping your sample at the right temp, which really isn't that hard without a whizzinator to begin with if you practice. However, if they look at your penis while you pee (observed test-watching the flow of urine leave the body and enter the cup) it isn't going to fool anyone but those that are nearly blind.

Getting caught using a device that fools a drug test is against the law in most states so if you get caught you will probably violate your probation as well as pick up a new charge. My advice, stop smoking while on probation. Yeah it sucks but so does jail or prison.
