"Parking sensor" cum laser detector

I'm thinking about getting a "Parking sensor" which also happens to detect on coming and rear laser detection, are these things illegal? I found one on ebay and wonder if anyone has had experience with them? Oh here's the link. [link removed by getsurfers] Cheers

Yes, these are illegal to use in the EU and US.

Don't try to use illegal things otherwise you will be in trouble.

Parking Sensors gives safety to your vehicles and keeps your vehicle in excellent condition. This has been mainly designed for SUV's, trucks, vans. The poor rear visibility of many cars, SUVs and other large vehicles increases the risk of hitting obstacles like small object, or even people when driving in reverse. With backup sensors installed, drivers can lower the risk of collision when backing up or parallel parking. So Using could bring safety to your car.

As a parking aid they are great, as a warning system for Laser based speed cameras they are a waste of time, by the time the device has alerted you to the fact the car is being tracked and you hit the brakes the Police will have the evidence you were speeding - Total waste of time - Mike
