In my opinion I think the Cobra brand is the most popular brand out there. Surely its far being the best but it seems that every kid that gets a car on his 16th birthday heads down to his local Wal-mart and buys one.
There is also the vivid shopper dad who browses around the store and thinks to himself "So what garbage should I buy today to get through my mid-life crisis"? Then he seems a radar detector (Cobra) and decides to buy it.
There is also the mad motorist who just got a speeding ticket. He is so mad at the world that he proceeds to his local Wal-mart and buys a RD to be protected from the LEOs.
These people they all buy a RD without doing research because they think 'All RD are the same, paying more than $50 for one is a waste".
Its sad but most of the radar detectors that I notice on people's windshield's are Cobra's and Unidens. Its a rare to see an Escort or Valentine one. Maybe those owners hide their units.
So what do you think is that popular radar detector?
