the good : sound be fantastic - provide a assortment of sound from foghorn , to train , to city street , to the rainforest and everything in between . I personally listen to rain every night . the sound obviously repeat but you can not tell unless you memorize the minor effect -lrb- for instance with the fire crackle - if you remember one part have two crackle than a pop - you will hear it again and realize it be repeat -rrb- . the bad : if there be a power outage and the power come back on - it will not work . I have to unplug it again to get it to work . on two separate occasion , we have a power outage and the clock have come back on . I have go to use it and silence . I can press the sound and the volume but nothing happen ; however , if I unplug it and plug it back in - it work . the ugly : the screen be bright ! there be a dimmer to turn up and down the light but even the lowest setting be very bright ! I have to turn it away from I to sleep . also , do not have anything with a radio frequency near it or it will pick it up . I have to watch my cell phone and baby monitor and keep they as a safe distance . very easy to use , very easy to set the clock , and provide soothing sound that blend perfectly with the background .
