Review: 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!
Review: 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....

### ⭐⭐⭐⭐⭐ Good clock!
*by M***3 on July 17, 2024*

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.

### ⭐⭐⭐⭐⭐ very pleased with the LFF 15" Atomic Clock *updated
*by E***R on April 4, 2023*

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)
