One of the Best

As an octogenarian with a sensitive bladder, a good nights sleep is a real challenge but with Brainwave Im OK. Getting to sleep is easy and getting back to sleep after a bathroom break at 3:00 AM and 5:00 is no problem either. Setting the rotation pattern was hit-or-miss but I finally managed through trial and error. (They need to provide instructions for this-Id have given the App 5 stars if they did)
To get the best out of it you should pay for the upgrade
