I was having night terrors, night sweats and insomnia especially during the hot summer months. Then when I would finally fall asleep, I was tired the next day, regardless of how much or little I slept. I had heard about sleep noise machines but wasn't sure if they really worked. I tried this one and I can genuinely say that my sleep has gotten deeper and more restful. I don't get night terrors anymore and I don't think I sweat that much anymore, and if I do I at least don't wake up from it and my clothes and sheets aren't wet. I feel better rested during the day and less groggy. Overall great buy and I highly recommend.
