Yep got one, and 2 of my friends have the same, another Viper guy and an SRT8 owner.
It is the only way to go for VA/DC residents since it cannot be picked up by radar detector detectors.
It is a heavy unit- thick gauge metal (I guess to shield it from outbound leakage)
So far so good with good early warning on radar, have on had one laser alarm and that was in MD.
The dark mode is especially kewl as the lights go out on the STI unit and display on the pwr cord near your lighter.
