Unfortunately, the software had already been registered and tested by Vorkäufer and I just could not use therefore. Since the manual is that the software only works anyway with this hardware makes a product key is not much sense and only this, that you send back the equipment and buying a competing product performs. On the other hand, I understand that you want to view the software before purchase, as this is often very deficient in GPS loggers. I can only report that the 1st Fix lasted after purchase less than 20 seconds, which I find very good. Not liked me the 3-fold slide "from / BT / Log", the locks too imprecise a dissolved better with my old loggers, since the paths between the engagement are a little larger, but ultimately not a big problem if you are in Typically, the log function and not use Bluetooth. It's annoying that I have to return the unit for such a thing. The Android app MTKutility (v2.5.2) has to update problems A-GPS, if other functions of the Android App are ok, I could not test. Because of the double copy protection I forgive only 3 points.
