Legal?
Radar detectors are prohibited in the Netherlands. However, a Stinger is one car computer, no radar detector, and therefore the use of this is also legal in the Netherlands. This has also been confirmed by the Food and Consumer Product Safety Authority. A Stinger, your computer in the car, functions just like a smart phone or computer on your desk: Depending on which apps (features) you put on it, your Stinger can perform various tasks.
In almost all Western countries, the use and possession of a Stinger is completely legal. In the Netherlands, too, the sale, possession and use of a Stinger are completely legal. Note, there in the Netherlands the use of a radar detector is prohibited, it is not allowed here to the Stinger Radar Alerting app to use. However, if you have Radar Alerting on your Stinger for use in, for example, Germany and return to the Netherlands then you can easily delete this app, after which you also fully comply with the laws and regulations in the Netherlands.
The use of the LaserShield app is slightly more nuanced. You may drive with Stinger Lasershield in the Netherlands, but you may not use it intentionally to obstruct a police laser check. However, you can also delete this app whenever you want.
All hardware is allowed
The possession and use of all Stinger hardware modules is completely legal in the Netherlands. The reason for this is that each individual Stinger module can perform one or more functions that fully comply with Dutch and European legislation and regulations. For example, the radar antenna is essential for the PoliceCheck and Safety Signals app, the GPS antenna for SpotList, Trajectory Monitoring Alarm and Trip Registration and the laser antenna for PoliceCheck, Laser Alarm (this function is in contrast to Radar Alarming fully legal in the Netherlands) and Safety Signals.
