It could have been much ... if it was the quality one would expect from this brand. Besides the batteries wear out very fast (especially compared to a VTECH pilot), the mobile function is very temperamental: it really the batteries are charged to their maximum. Indeed the mobile dock quickly. I even thought that it was ultimately failure (it is not far). The leaves are struggling to recover, and that even with fresh energizer batteries! I wondered if I had to send it in for repair ... Outside that (large!) Default, the mobile is very pretty and well captures the child's attention. The melodies are classical (with some false notes !!! it must be done!) And the sound function "sounds of nature" is itself harmonious (phew!). So there are 4 music themes, three great composers (memory Beethoven, Mozart and Bach) and the sounds of nature. The light function (on pilot basis) is quite useless. This is a fixed backlight vague, uninteresting. Level setting is brief: 2 sound levels, the possibility of light, mobile, or one or the other. There is a timer (about 10-12 minutes?). The remote control is proving fairly useful in my opinion. Namely (perhaps a fault of my model): the mobile is retriggers alone without reason after it turns off normally after about 10 minutes, several hours after ...? As for me, I do not buy it again. I have the traditional model of Fisher Price (one with jungle animals or cubs-straw): it is not perfect but seems a little better ... PS: the assembly is long! Not very complicated but long. Again, there is an effort to make, even if it is supposed to mount once.
