like some of the other reviewer , I too notice a very short sound loop . on most of the option it be annoying and not relaxing . but a few of the sound like the surf one , you can not notice it as much . also , there be complaint about the brightness of the lcd . I do not find that too bad . it be like have a soft blue nightlight . all in all , it be pretty good . the two alarm option be nice , the sound of a few of the track be decent , and it totally mask all the noise around I . so , I would recommend it if you can fine one sound track that be to you liking .
