Highly recommend this machien
because I have Tinnitus in both ears I need white noise to sleep.  My 12 year old grandson surprised me with this machine for my 66th Birthday. Wow!. I love it. It is battery operated or it can be plugged in. It has several sound levels and because I do some traveling with friends I can place near my head so it does not disturb anyone else. Have 8 different sounds. I use the rain one which is very soothing. I do wish though they would have put in a fan sound. I have noticed though I go into a very deep sleep with the rain sound and get 8 hours of sleep which is very unusal so guess the fan is not that important.
