XREXS Large Digital Wall Clock WiFi Sync, 16.5 in Large Display Wall Clock with Temperature/Date/Week, LED Big Digital Timer Clock with Remote Control, Alarm Clock for Home and Office, Auto-dimming

Everything worked as expected - except for the remote control which I had to replace. Customer Service was great and helped me out with that. There's everything to like with this. I got the RED (easier on the eyes at night), and the digits are very clear. You can control the brightness with either lo, hi or auto that is controlled via a switch on the back of the unit. I leave mine on auto and am very happy. Internet setup is easy. You have to surf over to the IP address of the unit (you have to be on the same wifi network as the clock) and make a couple of selections and hit enter - all done. Be aware that there is a small wire protruding from the case at the back of the unit - that it seems is the temperature sensor. Don't be tempted to push that back into the unit else your temperature readings may be off. Love, love, love the internet feature. So much better than the atomic clock units that are very picky about where they are positioned. My only potential criticism - the lettering for the day of week is a little off because they use display segments that are multi-lingual capable. I also hope that it will automatically adjust the time at the end of DST - we shall see. Get it - you won't be disappointed if you want accurate, big letter clocks.

I have a couple of other large red led-illuminated digital wall clocks, and frankly they all look fairly similar. That’s not a bad thing. I went out of my way to find clocks that specifically have this appearance. What I especially like about this clock is that it has a set-and-forget (WiFi) feature, at least that is the way it is advertised. So, naturally, I tested it. First, I set the time, and it was about a one or two seconds off. Next, I set up the WiFi (more on that below). After it connected, I looked at my phone’s clock, which of course, is updated continuously to AT&T’s network clock. When I did this, both my phone and my wall clock changed the minute synchronously. **** Set up *** There is a little space beside the battery compartment, where one can coil up the electric cable, but it does not fit well. You will need to work to get it to fit and replace the cover. The WiFi initially was not found on my phone, but it did eventually come up but I had to run the setup a second time to get the “Success” message that indicates completion. There is a dedicated appliance for the remote control. While this is convenient, for setting an alarm, even then it is unnecessary. The setup uses your phone (or tablet) to connect to your WiFi. It would make better sense code an app and list it on Apple’s or Android’s app stores than to have an ongoing manufacturing cost for the dedicated appliance. The fact that they didn’t think this through very carefully makes me worry a little bit that there may be other things that they didn’t treat thoughtfully either. **** End Set up **** For now, none of the set up items was sufficiently grievous alone or in combination that I thought I would deduct stars. I’m making a judgement call that a one-time setup nuisance is unimportant relative to long-term daily operation. If operational issues come up, I’ll update my post. For now, however, everything does what I need/want — i.e. large, appropriately colored and illuminated, display of accurately synchronized time. In my view, that’s worth five stars.

EDIT: if your clock isn't connecting to your wifi access point? Try connecting both to a 2.4 GHz and a 5 GHz access point. I think this clock only works with 2.4 GHz, which is older and more susceptible to interference...but has better range and device compatibility. ----- This clock works as advertised, and it's pretty good. But it could really benefit greatly from three things: 1. Six digits / HH:MM:SS. I don't care much about the day of the week, or the date, but if I want the precision of NTP synchronization? I want to see hours, minutes, AND seconds. This only shows HH:MM. 2. More frequent sync. I don't know how often the clock synchronizes to NTP, but it's not enough. When watching the minutes change next a GPS-sync'd clock, I often see the clock is off by 0.5 to 1.0 seconds. Not much, but again: if I want NTP then I want *precision*. It should be synchronizing every 30 minutes at least. Every 10 to 15 is better. 3. User-programmable NTP servers. For a professional setting, the ability to sync to the user's own NTP server is a must. Not everyone needs this, but also it'd be nice to have a main and a backup server. Something where you could add pool.ntp.org to always make sure you get a server, but you could add your own preferred server. Or a server with a known, desired, time offset. While less relevant to the general public, as an NPR member station's Chief Engineer? I can say with authority that if these 3 things were added? I guarantee you'd sell several hundred, if not thousands, of these clocks to NPR radio stations across America. They use precise clock timing to switch to/from their local programming and the national network programming. The price is perfect to get several of these per station; one for each studio and a few to scatter about the office, too.

This is NOT WiFi! It might be a fine clock, but when you order it based on the advertisement that it’s WiFi and then you find out it’s not, BAD! I ordered a replacement and it wasn’t WiFi either, so product description is WRONG!

I like wifi sync feature. Liked the remote. Not many chimes, I wish the chime can run every hour with a set time range.

I tried everything to activate the WiFi but nothing happened

Ya lo estamos usando durante un buen ntiempo y con mucho calor y el reloj sigue funcionando muy bien. Lo recomiendo totalmente!!!

one is not work , kindly arrange to replace

The clock description says wifi sync clock, false doesn’t sync with wifi
