Bests & Worsts Reviews from Amazon

The pace of this thing is faster than my normal bedtime breathing. I'd have to start breathing faster in order to use this the way it's intended. I have dry eyes. Staring at the blue light made me aware of the need to constantly blink. All in all, it made me wide awake and not sleepy. I'd bought it for those nights when I stay awake too late and then have problems falling asleep. Not gonna use it.
