I've had this clock for a few years now and its been flawless. Looks great, keeps accurate time, adjusts to Daylight Savings time perfectly and batteries last a very long time.

purchased this clock for an elder and they love it-it is easy to see and read!love that this clock will set the time it self and will be accurate!

If you haven't had an atomic clock before, be sure to read the directions and set the time zone/daylight saving time BEFORE you insert the battery. The clock will set itself, but you have to give it time for the hands to go around and get to the correct time. Have 3 of these, and they're all GREAT. Well worth the extra $$ not to have to reset them twice a year.

nice clock not to fancy works great always stay on time .great after power outage

We use this clock in our kitchen, high on the rear wall. It's exceptionally easy to read and an attractive design. Living in Ottawa, Canada, I was concerned that it might not pick up the time synchronization signal from the US government radio transmitter in Colorado (WWVB), but it did and automatically adjusted the hands on the clock. Be aware however, that the synchronization process is not instantaneous; in our case it took about 12 hours overnight for it to happen. The low frequency signal travels further at night.

It may sound silly, but this is sooo wonderful to think I don't have to take the clock off the wall twice a year and switch it due to the ridiculous daylight savings time. I would take about 15 attempts to try to put the clock back on the nail hole. I am so overjoyed I never EVER have to do this again.The clock is very attractive and well made, and the instructions were very easy. At first, the hands went around from 12:00 all the way to 12:00 again and settled there, but then I took my clock to a window facing West, toward Colorado. It started spinning again and landed on the correct time. Then, I took the clock far into my home to a direction facing East to hang it, and it stayed at the correct time. So, it's easy to get it to work correctly.I love it!

É um relógio bonito mas por ser atômico deveria ser mais preciso e isso ele não é. Ponteiros vieram desalinhados e no meu caso ele sempre sempre está adiantado 1 minuto. Já o ponteiro dos segundos não está em sincronia com o horário dos relógios oficiais. Não vale o investimento. Deve existir relógios atômicos melhores.

It worked as advertised .Very happy .

This thing is total garbage for any price, much less $40, and yes I followed all the instructions. I thought I was paying extra to get something with quality control. Boy was I wrong.When first given batteries, the hands spin for about 3 to 10 minutes to put all three pointed at 12. That works, all hands find 12, which tells me the hands are installed correctly.The clock does find the radio signal, because a few minutes after doing the startup "reset dance" to 12, it will start spinning again to set a different time. All pretty normal, it's using holes in internal cogs to figure out where the hands are.Problem is, it sets itself randomly from 3 hours to 2 hours 40 minutes late for every time zone it can select. If it's 12 Pacific time and you select Pacific time zone using the switch on the back, it sets itself randomly between 2:45 and 3:00. If you select Mountain time, it spins to 4:00 when it's actually supposed to be 1:15. Central, it'll go to 5:00 (when actually 2:15) and Eastern 6:00 (when it's actually 3:15).The minutes hand inaccuracy seems to randomly vary within a 20-minute range each time I tell it to re-synchronize with the radio signal, so you can't even just remember how far off the clock is and compensate.I found the hours hand can be spun on its fitting to fix the hours, which is in itself awful but at least helps fix it. Unfortunately even if I got the hours to set correctly from Fort Collins, that random 20-minute variance in the time setting means it's impossible to know how far off the clock is on any given day.The specs say the material is "Silver" which is usually an 'advertising lie' that means zinc, steel, chrome, or some kind of metal or metallic finish. Nope, all plastic with an ugly gray paint, and that plastic isn't even nice plastic. It feels like that soft bendy plastic they make Halloween pumpkin candy baskets out of.As I typed this out I tried using the 'Wave' button on the back one last time just to be sure. This forces the clock to reset and look for the radio signal again. It did the same thing as the four other tries. All hands go to 12, then it sits for a few minutes, then the hands start moving again. They spin up to the current time, then blow right past it and stop 3 hours in the future. Except this time the minute hand went to a time that's 15 minutes slow.Well, what if I just don't use the radio setting (that was the whole point of paying $40 for a clock)?Nope. Here's how you set it. There's one button you hold down, and while you're holding it down, the minute hand spins. It will only go forward, not backward. When you let go, it stops spinning. And then if it does detect the radio signal again, or whenever you have to change the battery, it will go back to the incorrect time.That means,* If your clock is 5 minutes fast and you want to correct that, you have to hold the Set button down for 10 minutes while the clock slowly spins through all 11 hours and 55 minutes.* If you overshoot that, you have to do it again.* If it ever hears the radio signal, it will reset to the incorrect time and you have to do it again.* If you change the batteries, you have to wait 10 minutes for it to spin to 12, wait 30 minutes for it to hear the radio signal, wait another 10 minutes for it to spin to the time it heard, and then hold the Set button for another 10 minutes to spin it manually, for a grand total of *it takes an ACTUAL HOUR to manually set this clock after changing batteries.*Whoever designed this clock is a sadist. Please, do yourself a favor and get something else. It's impossible to make a clock worse than this, so anything else you buy will be better.

It's nice having a clock that automatically sets itself. The clock is inside a metal utility building. I was concerned about the radio reception so I placed it near a window. It had no problem picking up the NIST radio signal. It set itself on the first try. I compared the time to the NIST website... it is one second slow. Which is fine, because the specs say it is accurate to +/- 1 second.There is a switch on the back for Pacific, Mountain, Central and Eastern time zones. Nothing for Hawaii or Alaska though. I don't think you can get the NIST radio signal in those locations anyway. There is also a switch to enable/disable DST. Which will automatically adjust the time when that occurs. Some locations do not use DST so that is useful. There is also a manual set mode if the clock cannot find a radio signal.The clock is easy to read and looks nice. I gave it four stars instead of five though, because the minute hand isn't exactly aligned with the tick marks on the clock face. When the second hand is at the 12 o'clock position, the minute hand is just a little bit ahead of the tick mark. This happens when the assembler is sloppy aligning the hands to the tick marks. Oh well, its not much.. but its enough to annoy me. I suppose I could fix it, but I would have to take the clock apart, which is not worth the trouble. Overall I am satisfied.
