I wish this clock would work properly. I bought two and neither will synchronize with NIST. In other words the "atomic" part of the clock (radio controlled in Salton's words) will not work. It keeps time as good or bad as any ordinary digital clock. I own two digital "atomic" clocks made by MFJ Electronics that work fine. I own two "analog" (classic round display with hour, minute, and second hands) that are "atomic" that work fine. I am very disappointed in these clocks.

I just recently bought this clock and was very happy to see that the clock works just fine. Put a battery in the clock and let it sit for 3 mins as per the instructions and vola! It sets with a radio signal from CO so it makes it very easy to set.
