I purchase this clock when it be power by a c battery and would have rate it five Stars . unfortunately when I re-order it recently , it have be redesign . it be now power by 3 aa battery which do not fit into its compartment , and so do not provide power to the clock for it to run ! a clock that do not run be no use to I or anyone else . I be return the new clock along with several other I order with the same problem .
