Quintezz Drive Control test result deficient

The Quintezz-Drive-Control I have now tested approximately 1 year in my car on suitability. The result is more than disappointing. Almost non-stop false alarms annoy a very short time. When driving past real speed traps, Lasermeßgeräten, etc. me the device, however, has so far never been warned. The only thing works, is the warning of fixed speed cameras using GPS, which can, however, usually knows already and now faced each useful Navi warns as well.
Conclusion: The acquisition of Quintezz Drive Control is a waste of money.
