I bought this here and ive been using it for about 2-4 weeks. not daily tho. the times ive used it its worked pretty well and i dont regret this buy at all. The only thing is that after a cold start when I click the logging button it sometimes detects like if was over a km away and a second later it detects me right where i should be (reflected on the log), this might be a problem with my location or just a small bug that i fix by Having to wait for the gps to locate the satellites first then press the log button and then I stop and turn log on again. im not sure if its something that just happens once in a while or what but i just rather not risk it when using it to see how much i walked or such.
When connected to my nokia 5530 it works very well with the Ovi Maps Application and VERY accurate. easy to install too.
My worst review for it would have to be for the terrible software that comes with it. its just slow and not very easy to use when your trying to cut a part of your saved log… but im searching for a alternative program.. maybe google earth will do… but im yet to download it..
it feels a bit cheap. but as ive used it it seems to be pretty solid.

Small (but not small enough to serve as keychain), very sensitive, decent battery life. The supplied software is reasonable but stopped working after 1 day (couldnt find GPS). Solution was to update GPS drivers from Silicon Labs site

This multi-purpose device does a great job at a number of things. I link it to my Blackberry for Gooogle Maps and I use it to a location data to my photos.
Fast locks and great battery life. It is small and light.
