I buy this clock because I want a `` set-and-forget '' clock that also have a thermometer . my major complaint about this clock be that in the two week that I have own it , it be never be able to sync with the atomic clock ! it keep try every night and never succeed . since return it be not worth the hassle , I decide to open it up and look inside . -lrb- I be a engineer , with some knowledge of how these circuit work -rrb- I be surprise to find that the the circuit inside look extremely cheap . there be a dry solder where the battery wire connect to the circuit board . the antenna -lrb- for the radio -rrb- have its wire short . everything look very sloppy in general . I then manage to separate the short on the antenna , hope that it would make the radio work . no luck . the radio sync still do not work . which be hardly surprising consider that the antenna itself be not cleanly wind ! it be unevenly wound by hand ! not machine wound . do I mention that the build quality be horrible ? I do not know if the clock 's circuitry have support for manage daylight savings or I have to reset it twice a year . I 'll find out in about 4 month I guess . but for the price , I guess it be a decent enough clock . it serve my purpose : maintain time fairly accurately and have a thermometer . I would really like to have the clock sync with the atomic clock via the radio though . Edit -lrb- 17-jan-2010 -rrb- : okay , so the radio feature finally work out , but it be still kind of flaky , work sometimes , do not sometimes . I be willing to now give this product the benefit of the doubt : maybe it be my location or something about the construction of my apartment that be the problem . I have revise the rating to 4 star now . would give it five star if only I have not open up the clock and see the shoddy construction .
