My In-laws bought this high quality piece of crap RadioShack detector a few years ago for both of their vehicles. One being a Nissan 350Z, (yes I know so sad). But anyway they have had at least 3 tickets in Michigan in the past few years but still think this radar detector rocks. I could not find any tests out there on the RadioShack models to prove to them they need better detectors, I am assuming they are on the cobra level. But if anyone has any info let me know.
