Good and no frill design. Bought it at around $20.
- Large and high contrast display, easy to read from far across a room
- Receiver is more sensitive (getting atomic clock signal immediately and during the day, when my old one was only correcting at night (Atomic clock RF signals travel better at night) about 10' from the nearest window). BTW, if you want to get the right clock immediately and during the day, go near a window with clear view to the outside and press clock sync button on the back for manual sync.
- Easy to follow instruction, and the web address for the instruction is printed right next to the battery compartment (handy, since we need to refer to instruction when we change the batteries)
- Simple timezone setting (one button to toggle four USA time zones) -- more on this on Neutral (below) also.
- Daylight Savings Time reflects the correct calendar period -- some of the older products somehow does not understand the new daylight savings time period in USA, but this one does.
- If you care about accuracy of the temperature display, mine was correct within 0.5 oF, compared to my lab instrument -- your clock's accuracy may vary :-).
- Instruction is not clear for the first initialization. Could only select the timezone AFTER the clock searched for the Atomic clock signal... (a few minutes), but the instruction does not say that. I thought I had a faulty unit at first. Better instruction needed.
- MAKE SURE that you plan to use this clock in continental USA (ONLY the 4 time zones, Eastern, Central, Mountain, and Pacific). But then again, I don't think you could receive the atomic clock signal if you are outside of these zones in North America.
- Fold up the instruction booklet and tape it near the battery compartment on the back -- you'll be glad you did in about 18+ months.
- I am a big fan of Atomic clocks -- one in almost every room in my house -- and found that most of the external temp sensor version needs battery changes every 6 month or so, while the non-external temp version, like this one, needs battery change every 12~24 months (all using alkaline batteries). So I use rechargeable for the clocks with external temp sensor (both the clock and the sensor) now, and alkaline batteries otherwise.
A couple of very important operating instructions that are not obvious and there is zero mentioned of them in the paper that comes with the clock:
1) When you first install the batteries the clock starts to search for the time signal from WWVB. While it is searching you cannot set any of the user-settable functions. The "SET" button is totally inactive when the clock is searching for a time signal. You can cancel the search by pressing the "WWVB SEARCH" button and then you can activate the settings mode.
2) You have to press and hold the "SET" button for about two seconds before the clock will go into the setting mode.
