Very satisfied with the purchase! Sounds different and their many, clean and nice, several kinds of white noise even, and also the sound of fire, rain, sea, forests with birds, hearts (only later at Chela tachycardia :))), clock, two lullabies on piano, cicada, train, etc. The sound is so realistic, the effect of presence is created and easily believe, that you are in the forest or on the ocean or outside the window bad weather-and you are in a warm bed!!!! I took it for the child, but I'll use it for myself! Looks quality if you doubt, then do not! Take it will not regret it! Came quickly, packed perfectly! Seller respect!!
