This white noise machine is wonderful. Its has different noises most I love the flute however is normally my favorite but it started annoying me because it was continuously playing the same exact few seconds. This would be even better if they could have done it to where it plays different flutes in a random pattern so you wouldn't hear it repeatedly. The other only issue I had was the volume down button has a delay or doesnt always catch when I push it so I have to push it a lot lol.
Other than that its portable very easy to use, and no having to fidget with an app that wont always play what you want to hear. It may be an electronic but its extremely user friendly. I like that all inhave to do is choose what noise I want an push the button a few times to get the sound I'm looking for the timer helps as well.
