Radar detectors

My dad's car was set up with radar detectors recently. They are currently in search for someone who can conduct a radar detector reviews. Each reviewer evaluates radar detectors differently , so it's not a good decision to conduct only one review. My dad is interested about the features of his detector and he would also want to check the range of the radar. Will they find someone soon? I hope so. This is just a new device in their car so they are pretty much excited to learn more about it's features.
