Dispense placebo-Warner

For the Note when boarding to fasten your seat belt on a costly gimmick. Although the purchase is legal - just the application in the car is illegal - and one should even be stopped and the device is discovered, then it will be really expensive. Although you can the unit under the head restraint "hide" - but "hidden" stay that way all mobile measuring points and laser guns of modern highwaymen.
But then it has at least beeps when you exceed the preset max speed. This goes on the highway then quite annoying. And if you again have to see what speed, now indicated by the device again - shame about the money, the device does not deliver what it promises.
Only positive effect - the glance at the speedometer and the road signs is again so important as it should be - the placebo Warner thank !!!
PS I leave a super radar detector - almost rarely used ...
