I get this clock because the alarm sound be call chime , cathedral bell , and something else I can not recall , but it turn out they be all very annoying . I really want a zen clock that wake you up with a actual chime but could not afford it . I think this might be a nice replacement . I have be very disappointed . as other mention , the nature sound be way too loud and can not be adjust . I have not use that feature since the first week I buy it . I be now in the market for a new clock . the alarm sound be drive I crazy !
