four star be suppose to be `` like it . '' and I like it . but I do not love it . the display and design be great . I be go to use `` sound quality '' and `` functionality , '' which I give only two star , to describe the two problem : the sound loop be just too short . and the quality of -lrb- some of -rrb- the sound just be not what it should be . what be frustrate be that the actual equipment , the speaker etc. , \* be of high enough quality ; the evidence be the rainforest sound , which be absolutely beautiful , crystal-clear , soothing , lovely , with a invisible loop that give you no impression of repeat -lrb- if anything it sound as if it go on forever -rrb- . it be everything you could want . in we own view , all the other fall short . the Thunderstorm , which we would love , the Chimes , which we would love , the Ocean -lrb- I think it be -rrb- , which we would love -- they be just too short . the chime be beautiful , the sound quality be crystalline , and after listen for 15 minute the short loop , the repetition of exactly the same order of the chime you hear and you know which chime be come next instead of produce a natural chime sound of random and hugely vary tone -lrb- which you could achieve by make it three time longer -rrb- , be irritating , not soothing . same for Thunderstorm . same for ocean ; you know which seagull be go to call next . sigh . and as for the rain , any Hollywood movie have better , more realistic rain sound -lrb- which be also synthesize in almost all case , beautifully so ; you can often hear the individual drop , as you can in real life -rrb- than this , which sound indistinct and fuzzy and , frankly , more like white noise than natural rain fall on tree and pavement . why -- why !? -- do not the idiot -lrb- sorry , but -rrb- who put in the money and engineering to make this a potentially terrific , perfect machine , whose design , feature , and hardware quality be all excellent , sacrifice on the one thing we really need and want and which they could easily provide : the sound themselves . rainforest be almost perfect : subtle , lovely tropical bird call , the rain gentle in the background . we use it all the time . thunderstorm and chime and ocean should and could be as good . if you create a watch that look great , whose mechanic you make perfect , for a good price , and then sacrifice on one thing -- it can not really keep accurate time -- you be a fool . would I buy it again ? it be difficult to find a good machine that be not over or well over a hundred dollar . so maybe , yeah , I probably would , just for rainforest . but it be so disappointing . the ec-b100 have huge potential . that potential be poorly use . ridiculous .
