Walt the atomic clock is not a 24-hour clock and its hourly announcement
goes off at 10:00 Pm. The other two 24-hour clocks are the talking cube
clock with a female voice which has time and alarm only. The second one
with a boston accent has countdown timer, 12 or 24-hour mode a beeping
alarm and a talking hundred year caendar. The first one was in the $25
range and the second one was in the $39 range. Maxiaids doesn't do a
particularly good job of giving you very much information. 73- pat kk3f
