We use the logger for our cycling and are very satisfied. The unit records exactly all the ways I did not expect more. The tours with us are between four and seven hours, the device maintains this time through without problems. An installation of the stick on the PC was not necessary, the transfer of routes from the stick to the PC is no problem. The synchronization with my Canon camera also works after the time zones of both devices have been matched. Update: In the meantime, the logger is with us for almost a year in operation, and we are still satisfied. The recording of cycling and hiking is very precisely, every little detour or side trip from the path is registered. We have the longest record 11:30 (with continuous motion) without recharging. The included program is spartan but adequate for my needs. The tours are presented in Google Maps, can be exported as GPX and KML.
