OCEST 12Inch WiFi Wall Clock with Auto Sync Time & DST, Easy to Read, Large Digital Display, Silent Battery Operated Wall Clock for Living Room Bedroom School Office Kitchen

After initial setup, leaving WiFi update time as 21:00 default, I found clock was 26 seconds fast the next morning and through the day. Since Second Hand is immobile from Midnight to 6 AM (reportedly to conserve battery), I suspect that was related. Judging from some other reviews, citing accuracy issues, could be related. Seconds was correct after the evening 21:00 WiFi update. I returned to Setup and changed to WiFi update at 07:00 (after the 06:00 Second hand restart). Second Hand accuracy issue is resolved. Clock is now nicely running within one second accuracy through the day, which is necessary for my application. Other comments - Hand action is very accurate. WiFi setup, through use of Smartphone is very simple and quick. Congratulations for an effective Software/Firmware and App. This is a well built product.

We have a couple of the radio frequency synced clock in our house, but they started giving us issues and not keeping time. Looking for replacements, I came across this WIF enabled clock. 1) Clock is silent - no ticking 2) Setup is super easy - insert batteries, look at your phone to find the WIFI network the clock is broadcasting for setup. Connect to it, provide your home SSID info and select your time zone and enter your NTP (time) server (I use the same server on all WIFI and LAN equipment). You can use "time.nist.gov", the NIST default server. Save this to the clock and you're off. You only need to connect to the clock during setup. 3) Uses 2 AA batteries like the old "atomic" clock, so no change - we'll see how long the batteries last. I'm assuming the WIFI only comes on when the clock needs to sync it's time, it's not on constantly. 4) Clock looks like photos in description - 12 inches wide, a white face and black plastic frame. The face has the WIFI wave symbol. My wife liked it better than the LaCrosse clock it replaced. Overall a very nice purchase. I ordered two at the same time for our bedroom and the den. The price was right and hopefully it will have an easier time dealing with daylight savings time than the old clock.

I modified my rating from 1-star to 4-stars based on feedback from OCEST Tech Support. Here's the original 1-star review: This clock came today and I tried setting it up, without success. That may change [it did], but the instructions do not match my iPhone's screens. I tried an online search with no success. I am tech savvy (Professor of EE at Stanford University, ham radio, etc.) so I cannot recommend this to others without the manufacturer doing a much better job. Unless tech support helps (no answer yet after several hours, but they're in China), I will have to return it. Well, Tech Support came through. The trick is buried in the instructions, but I didn't get that far since I was frustrated as noted above and there were at least two fixes suggested. The one that worked (and that Tech Support told me to do) was to open my cell phone's browser (Safari on my iPhone), enter 192.168.1.1 as the URL, and hit ENTER to open the settings page. That worked and the only remaining question I had was what time server to use. I left that blank and it worked. After I entered my standard time zone (PST = GMT-8), the clock got the right time (including DST which we were now on so we're now DST-7). So, if you read the above, this clock gets 4-stars. If you don't read the above and have the same problems that I did, 1-star. All clocks should use WiFi time (as this one does) instead of either manually setting or using WWV. I gave the clock 4-stars instead of 5 because a) the instructions are poor, and b) my wife and I would prefer solid hands instead of the wire used. Easier to see.

Really easy to setup. The clock transmits a WIFI hotspot, connect with a phone to automatically display the setup. It had already filled-in my home Wi-Fi name. Just enter your Wi-Fi password then scroll through a list to set the time zone. It set the time 2 seconds slow. The bad. Its fat hands are blunt and too short, the minute hand ending 1/2 inch away from the tick marks. This makes reading the exact time more difficult than a normal clock with pointy hands that extend to the marks. It has a sweep second hand. Time is actually continuous, but I prefer seeing the seconds tick off. That hand is also short. At least it is silent.

My wife loves the looks - nice modern and clean. I love the accuracy - updates from the internet web time servers. Connects to your internet network and updates once or more a day. Atomic clocks adjust time from the National Institutes of Standards and Technology over radio waves. What no one ever tells you is that you can't receive that signal unless you take it outside of your house for at least 2 to 3 hrs (clear sky - no tall buildings to block signal) - each time you want to update the clock time. For me - it's a waste of money because sitting on your wall inside the house it never updates. While this updates all the time using your own internet network. There's no ticking sound, and is just the right size for my wall.

Initial setup may be more complex to figure out than usual (simple http interface you need to access via devices wifi network), but once done it just works. In the end, I appreciate the simplicity.

Did not adjust to standard time

I've had issues with previously-purchased automatic-sync wall clocks that would lose connectivity and display time incorrectly. This one's been running for weeks and consistently shows the correct time. Initial setup was a snap. Highly recommended!

El producto es muy bueno lo remiendo

Very easy to set up and get connected to wifi. Looks great in my office and large numerals are easy to read from a distance. Extremely quiet operation when compared to the clock it replaced. The second hand stops at midnight at the 12 o'clock position to conserve battery life which seems like a good idea.

No problem with setting up wifi connection, though you may need to place the clock close to the wifi router / repeater to get consistent connection. Keeps accurate time as advertised. My only peeve is that the clock is about 1/2 to one second from the atomic time (despite trying different NTP servers). No complaint from me as long as the clock keeps accurate time to the minute (OK to within 10 seconds maybe). P.S. Absolutely no reply from customer service email

I was looking forward to this clock. Unfortunately when I received the package, the glass on the clock was cracked. The packaging it came in was fine just the clock itself was cracked. Will be returning it.
