I own 2 of these radio controlled clock, a silky August 2011, a silky February 2012. I had a similar model of Casio in advance, was always pleased with Casio. Wanted a new clock because the old tracks had substantial hand. Join two clocks error, the clocks fall out, the display goes out and when the clocks again start then to work state, which means: Date 01.01. wrong time, 12 hour format ect. Also no radio signal can then be produced, it appears Err - Bin with the problem as a watchmaker, battery voltage was measured and was okay, after a few weeks the same, time off, the display is empty, then working condition:. 01.01. wrong time ect. - A resume of the radio signal is not possible, error message Err -. But clock can be set only manually is not the meaning at a clock! So again a watchmaker. The whole happens involuntarily, not at regular intervals, times are a 2 months between dropouts, even 2-3 weeks. After 4 times the watchmaker clocks are unused at home, will try again to send, it is indeed to guarantee cases. Conclusion: not recommended
