Good things
  • Good quality build
  • Very long battery life (SiRFstarIII Low Power chip)
  • Both USB and Bluetooth are bidirectional port (can access to SiRF chip with SirfDemo)
  • Recognized as (pseudo) Ultra Mass Storage (as an USB drive) to get log file
Bad things
  • I said pseudo Ultra Mass Storage because to set the logging interval and erase the log file it (their software) sends nasty USB commands.
  • Erasing the log only works by formatting the device under Windows. The device recognizes a special USB sentence to know it's being formatted. This doesn't work under linux (mkdosfs), meanning it's impossible to erase the log file.
  • LEDs are difficult to see.
Summary
  • A really great GPS, perfect for Windows users.
