Initially, looks good, clear display, large number easily see across the room. Easy setup, and one of the nice things is not only is the manual good, but the instructions for setting up are ALSO printed on the back of the unit itself. Not many things worse than trying to find a manual two years later, or trying to search the internet for instructions when you can't remember how to set things. Also, nice that you can search for the WWVB time signal manually at any time, most units make you wait 24-48 hours to ensure the signal is detected. While they claim that daytime detection is problematic (and I understand propagation issues and such, as an Amateur Extra Clsss operator), the clock was able to find the signal mid-morning within 30 seconds. My only complaint is that there should be an accessory plug port or USB input port to plug in an AC/USB adapter instead of battery-only. I mean, how hard would that be, even if they didn't include the adapter itself?

The media could not be loaded. This is a great clock and the set up was easy. The clock shipped from the USA. The instructions are easy to read and just like the directions said it set itself.

I like the size of the clock and the size of the letters and I like how it is setup. I’m disappointed by the indoor temperature, I have this in an RV and it is obvious that it is measuring the wall temperature behind it instead of the room temperature. The outside temperature is more accurate but does not read constantly I find myself waiting for the next temperature cycle.

The clock worked great for 2 and a half years. I love the big numbers and the ability to see the outside temperature. But a few days ago the outside temperature started showing as --. I let it stay that way for a couple days hoping it would fix itself. Then finally I pushed the reset button and now nothing on the clock works. It just sits there ticking. Edit: Turns out im an idiot. The batteries were dead. Its back to working perfectly. I love this clock!!!!

I keep having problems with the outdoor sensor, which sits about 20 feet from the clock. The outdoor sensor reports temperatures about 30 degrees higher, and the batteries have to be replaced about once per month. I contacted their customer service and never got a response. Junk, save your money, do not buy.

ORIGINAL REVIEW: Clock was mostly easy to set up and has very good readability in normal room lighting. But there are issues: - The time zone indicators that appear on the screen are "PST," "MST," "CST," etc, which is Pacific Standard Time, Mountain Standard Time, etc., even when the automatic daylight saving time feature is turned on. There are no readouts that indicate DST, for example, PDT or MDT. As this review is written, DST is in effect, the clock reads the correct time and the DST feature is turned on. Yet, the time zone graphic states "CST," Central Standard Time. - There is no indicator showing that the DST feature is turned on. - The atomic on-screen status indicator either doesn't work properly or the user manual description of the indicator is wrong (or just confusing). The manual states that a flashing indicator means the clock is searching for the time signal, a steady indictor means a signal is received and no indictor means the clock is not searching for a signal. that seems straight-forward enough. But, it's not. When I press the button on the back of the device to cause the clock to begin a search for a radio signal, the radio icon begins to flash. Great, the clock is searching for a radio signal. But after a short while searching the indicator goes out which per the manual means the clock is no longer searching for a signal. Yet, the clock didn't reset to the correct time. So what's going on.? Will the clock automatically search for a signal from time to time? Must I periodically press the search button until the clock syncs? Who knows. The user manual states that the clock may not sync during the day due to radio interference from other sources. If that's the case, says the manual, the clock will sync overnight. That, of course, suggests the clock will periodically search until a signal is found. That's good. But why doesn't the indicator continue to flash so folks know the clock is still searching? Or why doesn't the manual say that the device will continue to search for a signal even though the radio icon is off? I manually set the clock for an hour ahead of the actual time to see if the clock eventually sets itself to the correct time. UPDATE: After 2 days, the clock connected with the NIST and set itself. The radio icon is on continuously and "DST" also appears, although the time zone icon still shows (in this case) "CST." So everything seems to work and all is well. All problems and confusion could have been avoided if: - The time zone indicators included "PDT, "MDT," etc. so that it was obvious that DST was turned on before before the clock connected to NIST and set itself. - The radio/atomic on-screen indicator continued to flash until the clock connected with NIST. If that occurred, it would be obvious the clock was searching for the NIST signal. But because the icon turned off after a few minutes, it appeared the clock was not searching. In the alternative, there would have been no confusion if the user manual stated the clock searches for the NIST signal even when the icon is not present. - The user manual states that the clock may not connect with NIST during the day due to interference from other radio sources but that it should connect overnight. It seems that it may take even longer than overnight to connect. If the user manual stated that it sometimes takes 2 or 3 days to connect, it would have made life easier.
