SharpAtomic Clock with Bright Color Display, Atomic Accuracy, Jumbo 3" Easy to Read Numbers - Indoor/Outdoor Temperature Display with Wireless Outdoor Sensor

Great Clock. Install it at eye level. The light, display & clarity are awesome. The back up battery works very well throughout multiple power outages without it draining when not in use like other electronics do.

It did not sync immediately with the atomic clock or the outdoor temp sensor. So I was ready to send it back. For grins I sent email to support--on a Saturday. They immediately responded!About the same time (after 4 days) it synced to the atomic clock.After several emails--on the weekend--regarding the outdoor temp issue, they told me to 'reset' the clock by removing the power to the clock and the batteries from the temp sensor. The key was to put the batters back in the sensor FIRST so it would have power when the clock was powered back up. The sensor synced immediately. (It took about an hour or two for the sensor to actually read the actual outdoor temp, but then it settled down.)I dreaded the resync with the atomic clock.... This time it synced in 20 minutes!! So all is now great, and I am impressed--and beholden--to the very timely support!! Well Done!!

The three inch time display is large, maybe too large for the room we installed this in; however, it’s easy to read and accurate. A few items to note to help with the other reviews of this product:1.) You can manually set the date and time. Read the quick setup instructions and it’s easy.2.) The atomic clock feature works, just make sure it can pickup the broadcast signal. Stuffing this in a cabinet with WIFI devices, etc, can impede its ability to synchronize.3.) The indoor and outdoor thermistors are pretty accurate. If your exterior sensor is baking in the sun, it’s going to read warm.4.) Put batteries in the exterior sensor and double check the “channel” it is set to before you power up the clock. It will synchronize quickly without any trouble shooting.5.) This clock can be either battery powered or plugged in. I have the clock plugged in, but leave the batteries installed for power outages. I’ve tested unplugging the clock to simulate power outages, and the clock continues to maintain time and temperature readings.6.) When battery powered, the backlighting behaves differently compared to when it is plugged in. I’m pretty sure this is to extend battery life and is completely understandable.7.) The blue, green, and yellow background colors are nice. The colors are closer to the product images on the packaging than the washed out colors from some of the reviewer pictures.Issues:1.) When power goes out and is restored, the backlight setting may need to be adjusted back to your preference. This is done by pressing the large button along the top bezel of the clock. Inconvenient, but not a huge issue unless you experience regular power outages.2.) There are times when the backlight flickers momentarily. It almost seems random and does not happen very frequently. It’s very subtle in the room where we have it installed and you have to be staring at it to notice it; however, I would not use this clock in a room where I could be sensitive to it (e.g. bedroom trying to sleep, etc).So other than the backlighting issues (loses a star), this clock works and behaves as advertised.

The atomic clock I received as a gift at least fifteen years ago has always worked like a charm; this thing, however, is a complete piece of junk, and is a perfect example of how far the quality of things has fallen.For starters, the clock has trouble synching with the time station in Colorado. It is not able to obtain a successful synch every night, like it's supposed to. Well, I thought, even if it can only synch every two or three days, that's not too bad, and the time should be correct. Then I noticed the outdoor temperature sensor was givng wildly inaccurate readings. I had the sensor mounted in the shade, out of direct sunlight and rain, so that tells me it's just a piece of crap sensor. The indoor sensor was usually pretty close to accurate. I tried orienting the outdoor sensor vertically instead of horizontally, and that seemed to help with the readings. Ok, I thought, maybe I'll be able to keep this clock. Then this morning, at about 6:30 AM, I look at the atomic clock and the time shows 9:24 PM. And get this, the symbol that shows the clock had a successful synch during the night was on! LOL, the clock synched with the time station and got the time wrong by about 3 HOURS!! I said that's it, I'm done. This thing is a piece of garbage, and if I can save at least one consumer from going through the frustration I have by leaving a review, I'll be happy. It's very sad that we literally cannot trust anything we buy anymore. I'm putting my 15 year-old atomic clock back up on the wall and returning this piece of crap.

My parents love the large thick numbers on this clock! The day of the week and date are very helpful for senior citizens who are still somewhat independant. Sits nicely on the tv stand (with an option to hang on wall). The vibrant colors make it easy to keep the data separate from each other. The indoor/outdoor temperature readings are accurate with their manual thermometer. READ the instructions, and over half of these reviews would be invalid... it clearly states the clock may sync in the middle of the night, when the radio frequency waves are less busy. It also tells about the accuracy and order of installation of batteries for the outside weather unit... these bad reviews are from people who didn't read the instructions. I am a very picky person when it comes to giving my parents their independence. This clock has been a life saver, and they depend on it to keep the days of the week clear in their minds. My roommate wants one, and he isnt a senior citizen (yet, lol). I will be buying him one for his birthday.
