This night-projector visually it all to a little girl who loves princesses stories. The idea is good but the design is still in review. Slide casters are easy to insert, and it makes sense to respect! What is not obvious at first glance. Once a smoothly inserted, it must be rotated to change the image will be projected on the ceiling. You can adjust the sharpness of the image by rotating the top of the lamp, it is not difficult. At the base of this lamp, a button to move the proposed pilot mode, projector or off. We can not have sleep modes and projection simultaneously. I thought something went at least on the base, but no, it's just improved lighting or a fixed projection. 3 notches to move the button on the selected mode are very close together and not too easy for handling by a child. Last, the batteries! This device requires 3 LR6 batteries (not supplied obviously), and no possibility of connection. While LEDs consume very little, I am afraid that it will take to invest in a stock of batteries. A good point, however, on the number of images available. I put 3 stars because the idea is good, it's solid air and I like the little girls but Philips can still work some negative points.
