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. 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.

It works well, but reading the bottom where the date is, proves to be difficult to read at a distance.

This clock is the best. Large enough to see the temp, date, and all information on the display from across the room.

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.

Zero stars (but Amazon won’t let me give it a rating of Zero stars (why not?) (So please read this review as choosing a rating of Zero stars.). 1-This clock never set the time by itself; I had to set the time manually. 2-A few weeks ago the clock reset itself to a completely random time. I switched out the batteries (guessing that, maybe this was the problem?) and reset the clock (manually) again because it didn’t do so automatically. 3-The same thing just happened again (reset to a completely random time). I need a clock in the bedroom, so my solution was to buy a new clock. Beyond disappointed with this product.
