Gamechanger! I was looking for a fan sound and this one has the perfect solution! I can finally get stop having to run my floor fan at night

There is really no "in between" with it. I turn it on, and absolutely no volume until you hit max volume, at which point even the most tranquil sound is downright disturbing. Someone heard it and took it for herself, claiming she could use the noise to drown out traffic when she sleeps during the day. I hope it works out for her. I was going to return it, assuming it was defective otherwise. The quality of the sounds were actually quite nice, but there was something wrong with my unit for sure.

It is simple to operate, convenient to carry or place, battery or current, wonderfulChoice of sounds. Love it. That's my feedback!

Update: After working with the machine, I've learned that each button has three sound settings. For example, pressing the lightning button a second time gets you more thunder with some rain. I still get the odd skip and the rain can be too much of a trickle at times, but it's a good machine and I'll stick with it.The seller responded to my original review, which I deleted as it was a user error situation. They were very nice and that kind of customer service is hard to find these days. Thanks!
