This may be the best thing ever! This portable white noise machine has it all, in a perfect compact size. With 36 different sounds I love the variety it gives me. So perfect and portable I can take anywhere, in fact right after I got it I had to do an overnight trip and it went with me. Threw it right In my bag. Easy rechargeable battery and USB cord make it convenient to charge anywhere. Adjustable volume and timer that lets me keep it on all night or set how long I want it to run. Not only did it calm me and I fell asleep quick, even with not being in my own bed, I also like turning it on during the day when I feel I need to relax and destress. Even when I am at home I love that it doesn’t take up space.
