Of course I have the disc is not taken, the measure would be for a test but a little too far. But I have at the plate shaken and the alarm went really promptly with a nasty tone going on. One has indeed perceived, even in remote areas, but in my opinion he is neither loud nor intensive enough. Compared to our smoke / fire detectors, the alarm is very friendly.
You can leave him not (except by removing the batteries but that is also useful). The alarm goes 180 seconds, then it is off. According to the manufacturer, the batteries hold the handle 2.5 years on the alert. If the batteries begin to run down, the handle logs (similar to smoke / fire alarms). The alarm function is given only with the window closed and grip. Open or tilt the silent alarm.
The processing is simple. The material cheaper plastic. So really great I do not find that now and I do not believe that these attacks will survive many years. For the price of about eighty euros I would have expected a little more.
Conclusion: the handle works, but quality and the sound could be more aggressive. A Locking function of the handle would certainly have been possible even at this price, and really would provide a sense of security, especially in tilt function. Therefore three star stay for this product. Better than nothing is the handle, but not really mature.
