As I said I would.
However, I had to also as described above enable the required protocols. That cost me some time and is even something for at least savvy PC users. With this program you can see the mouse namely shoot quickly. (So always at this mouse always think of the 57600 baud, never decide to do so) After a mistrial and a bit of practice with the reprogramming of SirfDemo succeeded easily. Remember, that your Bluetooth connection required for reprogramming the PC. (Incidentally, I had problems with my Belkin Bluetooth Dongle, it has also been reported in several other forums because the COM ports can not be set up properly). As you noted, the whole procedure is not very easy, and should be carried out only after an intensive study of various Internet forums.
After a single reprogramming, however, the mouse is ready for action.
Battery life is approximately 8 hours with fully adequate.
Now I am very satisfied with the mouse.
