I begin with what surprised me most: I expected a larger pilot, and he happens to be very small (not even 10 cm high). This ultimately is not so bad: we can take him everywhere. Despite its size, the brightness is more than sufficient and the day / night sensor and automatically works fine. I have not yet been arrived at 200h to use, but given the state of the battery, it seems to hold a charge very long. The micro USB fetching is ultra convenient (all mobile phone - excluding Apple - are equipped with this type of cables, no need to transport the small USB cable supplied with the pilot. In short, I highly recommend this cute little product (maybe a bit expensive).
