Good clock!
We love this clock! It was working great until a cat jumped on our mantle and knocked it down. I don't know what's wrong with it now, some of the numbers don't fully light up and we can't figure out how to change the time. I've changed batteries and messed with it for a long time until I realized I can't fix it. I don't have the heart to throw it away cause it still tells time, the wrong time but it does work. The size is great! I plan on buying another one soon to replace this one but just haven't yet. The temperature seems reliable, and it's very easy to read from across the room!

great to have both temp and humidity.
The item is larger than I imagined. Absolutely no problem reading the screen from way across the room....

very pleased with the LFF 15" Atomic Clock *updated
We've had the LFF 15" Atomic large characters clock 90 days now and have been thoroughly pleased with it. We've hung ours in a 90yo's bedroom, where having the large digits has been ideal. We liked that it's not backlit seeing as how it's in a bedroom. The LCD numerals are dark and well contrasted against it's slightly blueish hue background. Having the date and day displayed makes great for early morning wake ups/reminders. The dual temperatures and humidity percentages, that we're using for outside & inside (see more momentarily), is awesome, and thus far accurate. The atomic connection has been set-it-and-leave-it thus far (with one daylight "savings" time change under our belt). I am impressed with the range of the sensor sending strength, as it's on opposite ends of our 1430sq ft home with a brick wall and kitchen in between it and the bedroom it's in. i did have to relocate the sensor unit from under an east side eve, as the morning sun was warming it (and/or the brick wall) and skewing the early day temps. I moved it to the north side, which gets zero direct sun year around, and it's matched internet reported temps ever since. Speaking of the sensor, while i like the display of temp & humidity directly on it, note that it's a very small (tiny) display, relatively, so it requires being pretty much in hand's reach distance to read it (i was hoping to be able to see it from inside through our kitchen window, as dual feature, but being LCD and tiny, again, relatively, it didn't work for that for us); being able to compare it with the inside unit is neat though. The occasional pulsing red LED battery indicator is visible from longer distances and is a nifty feature as well. Back to inside, using it as a wall clock, we've not used the alarm or other daily-type options, so can't speak to those. We haven't had low batteries yet, so also can't speak to it's feature of having a low battery notification. We feel we're getting out $65 (+sales tax) worth with it, thus far... *09-2023 update: 3 times now in about as many months, upon awaking in the morning we find the time wrong, twice including day, date, month & year (temperatures and humidities unaffected). Each of the first two instances, we reset it to have it stay accurate for awhile, to then eventually be off again. The last instance was merely that the time was 2 hours off*late. One other time, the date was off by by several years (into the future) along with month/day, plus time off, PM instead of AM. This was with the device set to nightly auto-check the atomic signal; we've now disabled that feature to monitor the issue further... (additionally, fwiw, we're still on original batteries, in both the clock and the sensor; have had no low battery signal thus far; we're not using the alarm feature)

Nice Atomic Clock But A Few Things Could Be Better
I received my atomic clock. It arrived in good condition. Overall I am happy with it and I would have given it 5 stars but there were a a few things that I thought should have been included. What I think is great about this clock is that it has a large display. You can see the time from across the room with no problems. I have a large house so I appreciate the large display. I have several smaller atomic clocks that have the inside and outsider temperature and humidity. Those clocks stop the humidity level at 20% I live in the desert so the level is usually below that. With this clock the humidity levels go all the way down to 1% so I can now achieve accurate levels. Also I mounted the clock in the middle of the day and it did receive the WWVB signal mounted against the wall. That impressed me. I you have owned atomic clocks you know that the best time to get the signal is between midnight and 3am. What I don't like about the clock is that it comes with no hardware or template for mounting. I had to dig around to find the proper screws for it. It has 3 holes for mounting and trying to line them all up is a pain with no template. If you mount it with just the middle hole then it leans to the left because it takes 4 AA batteries (Not Included) instead of the design being in the middle like my other clocks. If you are kinda handymanish, which I am not, you may not have a problem. It took me an hour to finally get it right. It does have a kickstand on the back if you just want to set it on a counter or table. For $70 batteries, a template, batteries, and mounting hardware should be included. IMO.

very large read out
this clock is great, the wife and I have a large living room and the clocks large numbers are visible from up to 20 feet away. Easy to set up and has indoor and outdoor temps, with humidity.

Don't Buy
The atomic clock turns itself off at it's own will. I have a replacement. I does the same thing. It doesn't hang straight on the wall. not balanced. Daylight Savings works when It wants to. i does the same thing

What I like about this new wall clock
I like the clock’s display size, numbers are visible from afar, 5-10ft , provides accurate temperature readings internal/external, and overall easy to setup

Yes and No
It works fine and looks nice but…the date and day of the week section is very small and hard to read at 12 feet distance.

Date Size could be larger
Date and Temperartuire sizes could be larger, all Time size ok, date format should be able to change for example to Day-Month-Year.
