Nice clock if you are going to use it in a dark painted room/wall....the face of the clock has a white back ground with light colored numbers - chrome hour/minute hands. Very hard to see in a bright room. Display picture is misleading - hands look black but are chrome. Looks like the tried to make them darker on the pic and which whites out the clock some what. Wish the numbers and hands are black. May return.

I just bought this clock without knowing what the R-wave technology is about.  The specs for the clock on this Amazon site doesn't say that time zone settings are for continental USA only; I live in Hawaii so the closest time zone I can get is Pacific Standard Time.  I like the appearance of the clock and would like to keep it if I could disable the automatic time sync-ing and not have to keep re-setting the time.  I have been searching online to see if there are instructions but I have yet to find any so I am disappointed that I will have to return the clock or learn to adjust to the different time zone.  I do agree with other reviews that the numbers do look blurry when viewing the clock from an angle but the blurriness at an angle is not a big deal to me.

The clock is very nice and easy to use. One problem is that it has a couple of times reset itself to a different time zone.

I like this clock.  It looks nice in my office.  My only complaint is that it is intermittently not silent.  The second hand makes a grinding sound off and on..... and mostly on.  Was silent for the first month or so, then the noise started

Alarm on/off switch could be handier, but overall it's a nice clock.

Nice looking clock, but will not change the day of the week!  Find the alarm difficult to set, too.  Those two problems not working easily was why I bought the clock in the first place!  Also, the time can not be readily seen at night because there is no illumination, unless one turns it on.  For people with vision or a handicap problem, this clock is not for you!

I wanted a clock for when the power goes out and this is a nice little battery operated clock. I got mine in blue as it is my favorite color I like the fact that it has very large numbers so you can see it across the room. It can be set for regular and military time and it also has a thermostat on it that reads the temperature in celcius and farenheit. It also has a very large snooze button on the top. The only real problem I have with it is it does not light up when it is dark in the room. you have to push the light on by pushing the snooze button. I don't know what they mean  by "optically controlled" as this is definately not the case. This clock does alot  of things for the inexpensive price, but its not much good to use at night if you cant even see it when its dark. That is the reason it only received 4 stars and not 5 . I did receive this item for free for my review but the opinions are totally my own.

I received this Yxgood alarm clock yesterday and it was packaged in bubble wrap in a box. The clock is operated by a AC adapter and has a battery backup, a Sharp Looking Clock. It displays Temperature in F or C and also displays Humidity. It will also project the time on the ceiling and has a focus adjustment for different distances. Setting the clock Time, Date etc. was somewhat difficult even following the manual. Holding the Mode button and then pushing it steps the clock to different settings. With som patients it is possible to set all functions of the clock.
The feature that I like about this clock is not having to turn a light on etc to see the time, just look up. This Yxgood Alarm Clock would also make it a good travel Alarm Clock.

Cons: I give this 4 stars due to the difficult set up.

Wouldn't connect with the time signal where i wanted to use it as an alarm clock, so had to put it the other side of the room where it can't be read or used as an alarm clock.
According to my other two atomic clocks and two others at work that all agree with each other, it sets itself 20 seconds ahead of the correct time.
If it doesn't connect to the time signal it loses 3 mins per day.
I suppose the temperature and humidity are correct.

Even dimmed, the light on this clock radio is too bright to be used as an alarm clock, which is why I ordered it.  A black background with red  is much preferable for alarm clocks.  All alarm clocks with white/blue that I have seen are too bright for sleeping.  So, alas, I had to return the item to Amazon.  It would be great if you are not going to use it in the bedroom.

Well, as long as you DON'T have to carry this clock around anywhere, it probably works OK. The fact that it uses a watch type disc battery and has a screw on battery compartment lid, means, if you carry it in your pocket, or any tight place, the battery, apparently, shifts in the space inside the battery compartment and becomes partially disengaged from the electrical contacts. When this happens, the clock freaks out and all of the numbers on its display change from intelligible digits to unintelligible gibberish. I have been able to reset the clock by opening up the battery compartment (you need a precision screwdriver to do this), repositioning the battery and closing the battery compartment lid. If this was an occasional problem (i.e. "once a year" or so) it would be annoying, but workable, but I have had this clock less than three weeks and have had to reset it, like this, four times. To have to be constantly monkeying with the battery compartment lid, like this, in order to make this clock function in the manner that it is SUPPOSED to function is completely unacceptable. The bottom line is, if you need a reliable timekeeping device with a display that always shows the time (unlike a smart phone), this clock is not it. I am one of those people who doesn't like to wear a watch, but needs to keep precise track of time, as it moves. As such, I have found, that a folding clock, which I can carry from place to place in a suit coat or jacket pocket, is the best time keeping device for me. Unfortunately, unlike the Timex folding digital clock I had for ten years or so, this clock, is not it. I have ordered an Elgin Travel Alarm Clock and, hopefully, it works better. Unfortunately, this clock is a waste of money and a piece of excrement.

I do like this clock, and I tried to make it work in our living room; I had the perfect spot for it on our mantel, and it looked great. The minimal, modern design is just perfect for our decor. The problem arose when we needed to see what time it was. The picture in the description is lit from just the right angle for viewing, but we had to do some bobbing and weaving to be able to make out where the hands were. We ended up putting it in our guest bath, and the lighting in there seems to make the clock much more readable. Back to Amazon for another clock!

My wife wanted this clock to help her remember the day, date, and time. She likes it. (I'm not sure I'd say I "love" it with the 5-star rating as it's an inanimate object but it's a good clock.) I should add that it would be nice if it had an auto-dim feature for night time use as it's in our bedroom and we like the room totally dark at night. I'm sure it's objectionable to most people though, and there is a switch to turn off the display.

I like the clock and the time projection is clear.  The reason for 4 instead of 5 stars is that the piece that projects the clock only rotates front to back and doesn't twist side to side.  So in order for it to be projected onto the wall at the foot of the bed, the clock is facing the wall and not the bed so you can't see the face of the clock.  Or if you rotate the clock toward the bed, the projected clock is at a bad angle or not where you want it...

This clock is too delicate to be used as a travel clock, ours broke after a short time.

It's a reasonably good looking item. If you plan to rely on it as a clock, though, look elsewhere. Precision isn't this item's strong suit -- I'm seeing about 2-3min per month lag. Considering it's mounted on the wall, constantly adjusting the time isn't super convenient.

Looks nice...but there are NO HANDS on the clock.  Sent it back
