If there was anything to complain about, then the very light and non-dimmable display on the unit and the lack of a power switch.
But how anyone can complain about here, that there are any updates for your device, I can not understand for the life. If this is nevertheless an indication that the system is reliable. Updates are then usually offered when different things are in disarray.
The Lano 602 is certainly not the best models on the market, but for me is true for the experience of the past: it is sometimes worthwhile but to take some euro more into their own hands.
