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

So far so good thank you

I've had poor eyesight all my life. So I need a clock that is very visible. This one does the trick in many ways. First, it really is an atomic clock if you have wifi. The numbers in the time are a dark grey-blue or black against a light blue background. Underneath the time is smaller font, but still visible, the indoor temp is in the same colors. In the next block you have the month, date and day, and that is black on a bright green background. It's not a pastel green or neon green. It's more like the color of new grass in spring. The final block is the outdoor temp, (you get a dongle you can hang somewhere outside) has a bright yellow background. Again, it's not pastel or sun bright. Imagine the green of a new young grass blade, but in yellow. With the different positions and different colors I have no trouble reading this clock. I will warn however, that when you first plug it in, even if you set it, it may take a few hours for it to sync with the internet. I set it up, and then ignored it for a day. The next time I looked at it, the time was perfect.

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.

The transmitter and clock keep accurate information. My problem is the lighting, and the LCD readability. Lighting - it comes on very bright for 5 seconds at 1am and hourly after that, which can wake you up. The lowest of the 3 light settings is still too bright and is like a nightlight. Readability - the clock must be read straight on perpendicular, or from above perpendicular in order to read it, If read from below perpendicular, the numbers fade away. So probably not readable from your bed, or if clock is tilted backward like this clock is designed to do in order to use on a horizontal desk or shelf. It needs to be mounted straight up and down vertical, and low on a wall or shelf (3'-4' high), to be seen reliably. Leaning it backward reduces readability.If you do get it mounted at the right angle and height, the 3 backlight values are good for most daylight situations. If using this in your bedroom at night, the 3 light levels are generally too bright, and the lowest level will act like a night light, and can interfere with sleeping. They really need a lower 4th level, and ideally even a voice command for changing light levels like an Alexa connection. However, then you could easily get the time from Alexa.
