Box that will help you sleep better
It is an excellent product because you can use it even if you don't understand english, because the product have representative images.  I liked that the product is very portable and it can work without having a plug, it works with an external battery.  The sounds it brings are very attractive, beautiful and relaxing: white noise, wind, ocean, crackling fire, lullaby, thunder, rain and stream.  I tried it at bedtime and it really relaxed and helped me sleep.  It also brings a button to program the time you want it to sound (30, 60 and 90 min.) and two to control the volume.
