Great little machine
I am a light sleeper, it is not easy to fall asleep, and I often wake up at night, you know, I just want to try it, maybe it will help, if not, I can return it to Amazon and then I was really shocked by this sleep machine. On the first night, I chose a low-volume cket sound (without turning on the light), and I stayed asleep until the alarm went off! I strongly recommend this machine for people who lack sleep, it will help you!
