A well designed product, usable immediately. A very respectable battery life with two light intensities. The child is reassured by light and by the fact that he knows and has a habit of this pilot, the latter being mobile and independent. Listed little less it is regrettable absence taken for the sector, (everyone is not necessarily a computer or a USB port on hand), and the contact could have been made in a softer material. Also note as the pilot, a round label that it is better to remove before handing the object a little curious. Otherwise, a good idea to reassure the little ones with an object that becomes familiar and useful.
