The flagship of Snooper's range got off to a bad start with a very poor windscreen mount that caused the device to develop an irritating wobble.
Thankfully, it was more impressive when in use, with a bright and easy-to-read display and simple controls for setting a host of personal preferences.
The voice warnings - which also gave the speed limit - were good, but a couple of errors during the test saw it drop points.
