Does this run WITHOUT the timer? I need something to run a minimum of 10 hours. I fall asleep in about 3, but 5 hours later the raccoon on the roof wakes me up every damn time! A white noise app has drowned that out but drains my phone, even on the charger.
We use this one, and we love it.
The train sound is our favorite
