Hi! 

I finally got my NL-602u, and wanted to report that it works out of the box 
using
gpsd 3.6 via "gpsd /dev/ttyACM0". It performs very well under rough conditions
(small window, dark rain clouds). Positioning is quite accurate and a fix is 
quickly
acquired. Whats really nice about it is 115000 baud rate and 5Hz update 
capability. 

Maybe someone can add it to the hardware list on the homepage.

Regards, Benni
