Avoid Little Logbook device at all costs - totally unreliable.

I have been using Little Logbook device to track my car trips for SARS purposes for some time. I find this device totally unreliable and inaccurate. It seems that software gets upgraded without notice and this you only discover when you plug your device into your computer to download trips. It happened (not the fist time !!!) that recently I had almost a whole month of missing trips that could not be downloaded because I had to reregister my device for the same car. This in spite of me making sure that every time I start my car the light is flashing on the device before I start my trip. So no excuse for the device not properly attached.
