This clock absolutely DOES NOT keep perfect time. It's supposed to sync with an NTP server at whatever interval you program it to, but it syncs on reboot, then does not sync again until it's rebooted. It's a clock. But it's not a clock you should use for critical to-the-second time.

Love the look and functionality and made a 3D printed stand to angle it up a bit.The WIFI hotspot never turns off, so after you configure it with the SSID and password anyone that connects to it afterwards can inspect the webpage source and see your credentials in the clear. The hotspot should turn off with at some point, so I just configured it and afterwards put garbage info into the fields. So not quite as useful with it auto-connecting, but cool enough and will see how time changes without being always connected to WIFI. Also people could mess with it if they wanted, but the coolness trumps this and hence the 1 star deduction.

First, I had a little trouble with my clock, but the tech support was fantastic, and I have a clock now that is working wonderfully! It's small, about 2.5 inches high, but that's just the size I needed to sit beside a cable box since the ones here no longer have a clock on them. It has been extraordinarily easy to set up and got right on my home wireless with no issue. Note that this is a WiFi clock, so every so often (and you can change the interval) it gets the official internet time. You can even make adjustments if you have latency or other issues. I have another WiFi clock in my home, but it's so big that it dominates the room that it is in.

This clock is exactly what I needed for my room. It’s simple, with no unnecessary features like temperature or humidity—it focuses on being a clock, which I love. Even at night, the display is perfectly clear, so I can see the time easily. It keeps time accurately, and the ability to choose my own NTP address is a fantastic feature. I’ve already recommended it to my friends, and they love it too!

I absolutely love how customizable this clock is! The ability to stop the rolling seconds is a game-changer—no more distractions. I also appreciate being able to choose my own NTP address for precise time syncing. The setup process was a breeze, and connecting via IP address made it even simpler. Highly recommended for those who want a smart and functional clock!

For about a decade, I had a nice, red LED clock that was set using telephone Caller ID data. Shockingly, this broke on Frontier Communications (by hours) and even the advanced tech support people cannot fix it.Anyway, this is a terrific clock. You can make an easy adjustment to get it right down to the second, but in my application I'm not that fussy. (With no adjustments, it's about 4 seconds off due to Internet delays.) I received the firmware update so the leading zero in hours could be turned off. Your choice.( I want to see 1:27 not 01:27 )This is a terrific clock with great tech support. I had a couple of questions. They were always answered within 12 hours.

I bought 2 of these Matrix clocks from this seller here at Amazon, however from a prior listing page at Amazon.There's just one major head-shaking flaw with these specific Matrix clocks: The time is absolutely not 100% accurate, even after you boot the clocks over and over again and then the clocks synchronize with the Internet time servers. Both of my clocks default to about 6 seconds slow. And it doesn't matter what Internet time server you choose to use; I have tried several. The default sync from all Internet time servers does transmit the accurate time to these clocks, but the clocks cannot set themselves to the exact time in spite of the accurate data received.I have other Internet time clocks that I currently use and have used, and none of them have this flaw. Of course, the idea of clocks that sync to Internet time servers is that as the sync occurs, the clock sets itself down to the accurate second. But not these clocks.Now, obviously the company selling these clocks know of this flaw, which is why they elected to add a setting that allows you to program in a time offset. This setting allows you to have the clocks either subtract from 1 to 59 seconds or add from 1 to 59 seconds every time the clock syncs.Again, I have used many Internet time clocks for years, and not one of them required this time offset feature. If you do not mind having to figure out the accurate time offset and then program it in, you should consider buying these clocks. If you feel that these clocks should set themselves to the exact time from the data received without needing an offset correction at all, then you should not buy these clocks.Of course, there might be new firmware created one day to fix this unnecessary flaw, but how would existing buyers know if and when it is released, and how to get it.

I bought this clock for the living room, and it’s fantastic! It displays time clearly in any lighting without needing a backlight button. The seconds display is highly accurate, syncing to Internet time sources instead of unreliable WWVB signals, with customizable update frequency.The versatile display includes a 12-hour format, and all features work flawlessly. Affordable and precise—highly recommend it for anyone needing an accurate clock
