negative : it would be nice if the display would turn off . even on the lowest setting it light up the room . negative : the Oceanside sound loop too quickly . it be one wave over and over . you can actually hear where it start again and sound more like a skip record . I purchase it for this sound and think it would be of better quality . there be no attempt to even sound random or mixed . after a couple of night it be more like listen to a dog chew on itself . positive : I like the look and feel of the design . most of the other sound be pretty good but not the sound I really want to drift off into sleep with . I 'll try a few more sound but believe this will be on my return list this winter .
