Easy to read
The clock has large number display that makes it so easy to read even from the other side of the house. I put it near the front door so I know when I have to leave for work. It would be really good if the clock can adjust for daylight saving time by itself.

Best Atomic Clock Ever!!
I have had at least half a dozen of these “atomic” wall clocks and this one by far is the best ever. It’s larger than most and you can clearly see the time, temperature, etc. from a nice distance. It was easy to get the time to set which is an odd thing to me because you think it would be easy with all of these clocks. I live in AZ and we do not recognize DST so it is always an issue and most often, I have to fake it by putting in another time zone.

Great! Love it.
Great! Love it. This jumbo-size (14″) wall clock is just what I wanted. It’s my third atomic clock, and they all keep excellent time–within a second or two of each other and with my desktop. It can be even be read it from across the room without my glasses!! Top row has AM/PM, TIME: H:M:S and an indicator the ‘atomic’ signal is being received. Bottom row has inside room temperature, Day-of-the-week, date: MMM/DD, and to the right, the OUTSIDE temperature. The day and time indicators are more difficult to read because they uses a different font.The clock comes with a small ‘box’ that you place outside (I have it in the window sill) and its reads outside temperature and connects wirelessly to the main unit. The instructions suggest placing the box on a north-facing wall, so sunlight won’t hit it and affect the temperature reading. As I sit here on a Saturday night, the inside temperature is 74 and the outside temp is 46. (a very handy feature when you first get up in the morning)It uses 4xAA batteries for the main unit and 2xAAA for outside sensor. Based on my other clocks, you should expect a year or more of battery life, maybe more since this clock has no moving parts, just the LCD display.

Click Works Well, Sync Doesn’t
This is my 2nd of these clocks. My first one broke when I dropped it….,I like the features of the display and the large easily read numbers. The only issue I have with the unit is that the radio synchronization only works when the unit is near a window or on an outside wall.The sync functionality has not worked for me on an internal walk (stick/drywall construction, aluminum siding).

Great Clock – Easy to read, accurate, and handles cold temperatures.
This review is for the LFF Atomic Clock 4.5″ Numbers, Atomic Wall Clock. I bought this to use in my unheated workshop. The photos are taken from about 30 feet away near the opposite side. The clock is at 12 – 14 ft above the floor. It’s easy to read the time from anywhere. The temp and date are easy to read within 20 feet. It’s worked fine in below freezing conditions. No problems at all so far.Set up took about 5 – 10 minutes as I cycled through the settings too many times. It’s straight forward if you read the instructions first ;). The remote temperature probe connected right away. I have it in a sheltered location and it seems to be doing fine.

External sensor not working!
The external sensor is not working. It shows half of the numbers. I have changed the battery to no avail.
Kitchen Pro –
Easy to read….but…
The clock looks great and has wonderfully large digits for easy to read at a distance. However, the weight of the unit with batteries on one side makes it hang crooked, and there’s no way to hang it straight and level without a second nail or hook in the wall.
John R Partington –
That the unit I received will not receive Atomic clock reception, as it is intended for the USA( EST,CST,MST,PST,AKT AND HST) the display is brilliant. Just disappointed the atomic setting will not work.
