I hesitated to buy it saw some very negative comments and I hesitated with the version with pilot and melodies! Finally I do not regret my purchase and will buy a musical mobile for baby! I'm not yet used it for the whole night but to monitor baby when I leave it in his bed, with the trigger by voice. The zoom function is practical, too bad we can not point the camera remotely! The image is sharp, which either in daylight or at night! And the very simple functions on the receiver! I for one am glad that plugs into the camera industry, I did not want a device with a battery change every day: - / so that's a positive for me and a selection criterion this product! Bought with a discount on Amazon, I am very satisfied! (I do not think I would have bought at high prices as a bit expensive !!)
