Perfectly packaged, reflecting the seriousness of the manufacturer, the pilot is distinguished by the possibility of immediate use out of the box, requiring no load (partial load of more than half of autonomy is already present) and not requiring the use of the manual for operation. Its USB port and cable are all ad hoc identified on, nothing complicated. This night is given to 200h max, but we must foresee and avoid this ideal autonomy pilot with an automatic brightness sensor for its start and its extinction (in addition to the on / off button of course), if the bedroom curtains remain closed longer than the length of daylight and darkness during the baby naps, autonomy is inevitably somewhat reduced. That said, for the moment, it is very stable and the small backlit display which indicates the remaining battery does not show a rapid discharge, which reassures its consequent autonomy.
