The Big Red Rooster White Noise Machine has some really great noises that sound very authentic. My favorite noise is “thunder”, I love the sound of a thunderstorm. My daughter really enjoyed the “summer night” & “ocean”. I liked that your could set a timer for the amount of time you would like for them to play. It usually takes me a lot an hour to get to sleep so being able to set it to 60 minutes is great! You can also set it to quiet or loud. 
The white noise machine has a plug in but you can also 3 AA batteries so you never have to be without it. 
Overall we enjoy it, however, I think it would be far more useful if it was also a clock or radio, but that’s just a personal preference.
It has gotten a lot of use so far! [This review was collected as part of a promotion.]
