On the subject of accuracy: deviations from 15m, as described by others, I could not tell. What I could understand very well, however, was the deviation caused by the satellites - are located on different days identical played routes side by side. This is the mini Homer terrible reproach
What I personally on the device is not as good feel that the display 19:00 to 7:00 is always dimly lit. For me, it would be entirely sufficient if the lighting anginge keystroke - now she is in the same period brighter keystroke.
The absolute hit it would be if the device would have Bluetooth - the corresponding icon is already in the display available (anticipation is spreading).
The telephone contact with the supplier leaves a positive impression and also the replacement USB cable as well as additional documentation to operate the mini Homer to proprietary software arrived promptly with me.
