First test article of this kind, so no point of comparison with others, but seems to do the job, always hoping it will not be necessary to use it in a real case. Attaches well on the windshield, does not occupy too much space. The integrated battery can not be held 1 pm, but it's there, and eliminates the need of power supply wire for short trips. The software to trace the route on PC running smoothly. So no major criticisms to date.
