used the sound machine every night since I received it. I love the variety of sound choices and the fact that I can set it on a sleep timer if I choose to. I havent found anything I dont like about it. I plan to purchase another to give as a gift. Up the decibel range for Tinnitus users I hva Tinnitus and use sound machines to block out the internal sounds that ocurr with this syndrome. Yhe sound machinr nrrds to have an increase in DB range to allow the listener to block the inner sounds /noises that come with Tinnitus. Not loud enough !!!! Not so sure... I gave this to my mother for Christmas two years ago. I just came back from visiting her on the East Coast and it was still in the box, sitting in the rear of her van. She let me use it while staying with her for 2 months. I had the machine on its lowest setting and it was much too loud. If I could dial the volume to my needs, itd be the perfect machine. Like others I had to muffel it with a towel or washcloth to get it lower.. too bad. Im looking to buy a machine for myself right now and would love to have this machine, if only I could control the volume...too bad... THE REAL DEAL!!! I live only two miles from a beautiful beach and never heard such great surf sounds before now! This
