The GPS antenna works fine and syncs quickly. The size of the device can easily carry with you.
The biggest problem is the supplied software. It is not intuitive, unnecessarily complex and rather slow. Unfortunately, the device communication protocol seems the owner, and there are few alternatives to the supplied software. However, one can easily export the data in GPX format to process with third party software.
Another concern, which would have been easily avoidable, is that the large button is fairly sensitive to accidental pressures, so the GPS stops and restarts during the day, as long as it exerts a light pressure on the button .
Finally, the two LEDs (red and blue) indicate the status of the unit (ON, in the search signal, find the signal, etc.), by a blink code, not always easy to decipher.
Overall a good buy anyway.
