very nice clock . it be attractive , the display contain the information I want , the numeral be large , it be light & small enough for travel . be solar power be a big plus as no more battery to buy . that the temperature read a couple of degree too warm be minor . set up be straight forward . a lighter background would allow view at a greater distance . I do not use the alarm so can not comment on that and the atomic part be not relevant for I . solid 5 star .
