Atomic Clock with Indoor Temperature and Humidity, 12.5 Inch Self-Setting Digital Wall Clock or Desk Clock, Battery Operated Digital Clock Large Display for Seniors, Auto DST

Great clock, no problems, no issues, works like it should. Is light as it is, I’m surprised there is two holes in the back to hang it up, but that’s ok, least it comes with a little template, which I wish most stuff would lol Pretty easy to set up. I didn’t even use the instructions. Just look at the back of it, lot easier to set up than my last one.

Great Wall clock! Large size makes it nice and clear and legible, even from a distance. I like seeing the date and temperature at a quick glance. Takes 3 AA batteries. Excellent customer service. Wish the price was lower. Great product.

Such a great gift for someone who loves numbers and wants to see time down to the seconds, temperature, date, day of the week, ect. It was easy to figure out how to set it. Large display helps seeing it from a distance. We don't use the alarm. So it's quiet. The clock can be hung up or use the stand to set it on a table.

I wanted a clock in my bathroom so I could plan my time wisely when getting ready for work. Unfortunately, I either have fabulous hearing or OCD tendencies because I believe I can hear all ticking clocks within a 50-foot range. This clock is silent. Phew. It is easy to read, provides a LOT of information, and looks pretty slick. The only issue I've had is that, for some odd reason, the clock is an hour off and every time I change the time... it switches back. I still like it and now know that my clock is an hour behind. :)

I like having a few clocks around the house where it's easy to glance at the time... and I like that I don't have to wonder if the time is right or remember to fiddle with these to fix the time, or when the time changes, because like my phone and computers, these automatically update themselves. These have larger sized time digits that I can see across the room and temp, date, and day, although they're smaller. These aren't fancy but functional and reasonably priced. Also nice that these have a stand to sit on a piece of furniture and places on back to hang it on screws or nails. One consideration is that it's not backlit so needs some light in the room to be readable. Uses 3 AAA batteries. I like stuff that's low maintenance and this fits.

It's exactly what I thought. Perfect size and easy to set up.

I'll comment on two aspects of this clock: the atomic function and accuracy. Since it's sold as an 'atomic clock', I'll start with that. Atomicity ------------ I received this clock 12 days ago. I live in a top-floor apartment in a 3-floor building somewhere on the west coast of Los Angeles County, California; only around 880 miles from Fort Collins, Colorado. That's where the National Institute of Standards and Technology (NIST) broadcasts the 60kHz WWVB atomic-clock-based time radio signal. That signal has a 2000 mile radius and covers the entirety of the contiguous United States and reaches significantly large parts of Canada and Mexico. The building where I live doesn’t have a lot concrete or large metal structures; there isn’t a single tall building in the way between the clock and the low hills looming in the horizon; there’s no source of significant interference— powerful electric motors, high power lines… etc— nearby and the weather’s been beautiful those past 12 days. In short, as far as sight, I have clear near-line-of-sight to the source, and there’s nothing to cause poor reception. I’ve even used a compass and map to get the best directional cue after the first few failures. Yet, it seems a tall order for junk manufacturers to make products to receive the signal under these near-ideal conditions! I wonder if they even test their products in the US at all, the US being the only consumer, let alone test a statistically representative sample of locations within each state. First off, when I turned it on it, it did not receive the signal. I tried getting it to manually sync by pushing the WWVB button and waiting for it until it gives up— after 7 whole minutes, several times, including in the balcony, to no avail. It was very frustrating! Over the next three days I tried several spots and it would always fail, both manually and automatically. BTW, this clock and most of its ilk, like the not-as-bad 'Sharp' I purchased about 6 months ago, attempt to auto-sync several times late at night. According to this clock’s manual, it attempts the sync hourly for up to 3 times, starting at midnight. On the 4th day, I noticed that it had 'magically' synced. I noted the ‘sweet spot' where it did and kept it there until the 10th day. Throughout those 10 days, it was a hit-and-miss. However, it auto-synced in the ‘sweet spot' the last 3 days— of 10— in a row. On the 10th day, I noticed that time had jumped 40 minutes forwards, despite the indicated successful sync… just like that! And that's when I decided to return this piece of junk. Just for the sake of completeness, I found the ‘sweet spot' to be a tiny 2x2ft area on, and within a few inches off, a specific wall, and much lower than where one would normally hang a clock. Furthermore, manual syncing in the 'sweet spot' at an arbitrary time of day doesn’t work! So, it’s only auto-syncing that works, during the night, and only in the 'sweet spot!' Accuracy ----------- The magical 40-min jump aside, I noticed that without syncing it would gain nearly a full second daily (~0.9.) That's about 5.5 min ayear. The manual even specifies 'free run' accuracy as ± 60 seconds, per month! Is that acceptable from ANY timepiece in this day and age? I don't think so. It means this clock uses possibly the cheapest oscillator out there. In this regard, the 'Sharp' I already have loses— instead of gains— about 0.7 second per day; it uses a cheap oscillator too, just not as bad! Worse yet, even when it does sync, it doesn't correct the ~0.9 second it had gained the day before! It seems that it's either designed to ignore minor drifts, or the ~0.9 second drift is itself one of the, many, design flaws. Either way, what's the point of ‘atomicity’ when accuracy isn’t a design imperative? Notes ------- · The clock indicates successful syncing by the 3 curved lines (called “wave” in the manual) appearing above the fixed triangle (called “radio tower” therein.) · Gain and loss estimates are best-effort, and based on visual comparison with time display on a computer which syncs 3 times per day with NIST's NTP (Network Time Protocol) time servers. · The 'Sharp' I have has a similar 'spotty' syncing problem; it, too, has a poor WWVB radio receiver. Unfortunately, it worked somewhat acceptably in the place I was before, and my return window has closed many months ago. Apart from the weak receiver and oscillator unbecoming of the brand name, it's rather nice and sturdy, unlike this one. It supports up to 3 outdoor temperature sensors; it comes with only one, though. It's just not worth the $65 I paid Amazon for it, on account of the weak receiver. For reference, here it is: https://www.amazon.com/dp/B08S31FRDQ?ref=nb_sb_ss_w_as-reorder-t1_ypp_rep_k0_1_9&amp=&crid=YK3RQ60CQKOD&amp=&sprefix=sharp+ato · If you think you can live with manually setting clock, think again! This clock— and most of the ones of its ilk that I've checked out on Amazon— seem to have the design flaw of assuming it will successfully sync most of the time. Thus, their designers seem to pay little attention to how it will be set manually. There are only 2 buttons: Up and Down, to set just the hour and minute. The same butons are used to set other date components using the “Time Set” button to switch contexts. If you don't have nimble fingers and lighting-fast reflexes, you'll find it very trying to correctly adjust time to the second. And given how quickly in runs adrift, you'll probably have to go through that several times in a week. If you care for accuracy at all— as you should be if you're considering an atomic clock, you'll probably find it easier to just 'walk it' like a dog for up to half a mile to find a place where manual syncing succeeds! It's ironic really, it's a clock— an 'atomic clock', mind you— yet designed as if it were to be incorporated into a stove or microwave oven as a supplementary function!

I love this clock! I have it hanging in my bathroom as a perfect way to take a look and ensure I am on time preparing for work or whatever I have going on. Love the fact that it includes temperature, humidity, etc. with large and easy to read numbers. Big plus is that it is set automatically, so, I do not have to worry about setting manually. It is accurate and appears durable while being light weight.

Love the big screen and the backlight
