My retarded buddy was turned on to radar detectors by watching my videos on youtube and decided to get himself one as well. I repeatedly said do not buy a cobra but what does he do, but gets a cobra. The same one as the first one i had bought before i knew what was good the xrs 9540.
He wanted to see how well it did to my bushnell.
The first run i got him with out setting the detector off. He was a little upset
The second run i decided just to do constant on just to give him an idea of how poorly it does. The test courses was only 2/10 of a mile with a little hill in the middle. He stated that the detector didn't alert till he seen my car.
What a dumba$$... I told him not too now he is out 150$ and the risk of getting a ticket.
