  • quality clock
Color: Black
i always wanted a clock that will give me the indoor and outdoor temp, was shopping around on Amazon. Sharp's clock is not the cheapest by all means, the moment I opened the package the clock screams good quality, it was made out of plastic, but does not look cheap at all. The atomic clock and the temp function all work as intended, screen size is big and easy to read. Overall, I'm very happy with the purchase ... show more

  • Wonderful clock
Color: Black
We love this clock. The larger screen, the bold numbers and letters are just what we wanted. It was so very easy to set , plus I can use the second counting when I need one minute for a timer.

  • Nice Big Numbers
Color: Black
I have had a lot of atomic clocks in the past. This one though beats them all. Easy to set up. Transmitter sent temp almost immediately. Of course, the big numbers have to be the best part of the clock.

  • Great item!
Color: Black
We love every features about this atomic wall clock, my only single complaint is the font size for the day, month does not match all the other information this clock displays. Other than that it's a well operation wall clock, simple to setup, hang, it does all that is in the description.

  • What an I missitng?
Color: Black
I set this up according to the directions. (btw the instructions say AA batteries not included for the outside unit. The outside unit takes AAA. First pages says AAA for unit, 2nd page says AA). Anyway, was able to set the clock, but like another reviewer stated we can't get the little satellite icon to stay illuminated. But, what's more frustrating is the outside unit is not communicating with the clock. It did at one point, but have tried many ways to get the clock connected to the satellite. Anyway, we had both the clock and the unit on Ch 1, then tried ch 2 (both the clock and the unit) and it still isn't giving outside temps. Seems like I'm doing something out of order. Anyone have some ideas? Thanks!! The clock seems well made and is easy to read. But is the little satellite icon supposed to show when it is connected? It goes off, and sometimes it's there with the little lines flashing and sometimes it just shows the satellite with no lines. HUH? UPDATE: It finally started working. All the proper icons are showing. I think I just didn't wait long enough for all the things to catch up. It's a really nice clock. ... show more

  • Easy to set up (mostly), easy to read, poor indicators, poor user manual (in some respects)
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. ... show more

  • Needs More Features and There is a Design Problem
Color: Black
On the plus side, it is very easy to read, has three different sensor channels and has a great viewing angel. The outdoor sensor has good range. It has a built in stand. I have not used the stand, I have wall mounted mine. I cannot say how good the viewing angle is on the stand. As the clock is huge, you would really need to hunt for a space if using the stand. Here are the negatives: The sensor is very susceptible to moisture, it will stop working. You then have to dry it out for a while and reset the clock. The sensor needs to be place where it is dry. The case for the sensor has only a cut out for hanging with a nail or screw. That might work for some people, but also having a hanging hole at the top of the case is much better. I dangle mine from a string in a dry outdoor space. The bottom line. The unit works as designed as long as the sensor remains dry. It lacks the features of a weather station, but is easy to read. The clock lacks a forecast or humidity feature. That would be nice. It isn't a weather station despite having an outdoor sensor. Don't expect the clock to receive the atomic timing signal if you live in the Eastern part of the US. This is not uncommon. The signal is pretty weak in the East. ... show more
