Query: Can't Sleep Without It

Perfect for a stressed out light sleeper. My husband was switched to the night shift and would inevitably wind up waking me when he comes in at 3:00 am. Now the sound machine drowns out just enough noise to keep me sound asleep and boy what a difference it makes. The aromatherapy is nice as well but to be honest I don't use it that much. The nature sounds were worth it by themselves. Highly recommend this product and I would have paid double for it.
