I love this it’s simple and the buttons actually say what they do so it’s easy to set the time and alarm and is Loud to wake me up I like it has a hi and low light setting also

    • Digital clock
Color: Midnight Black-white Led
The clock was easy to set up. Supposedly the battery is able to determine the correct time if the power goes out, so the clock is always accurate. I haven't had a chance to prove this, but it's working great and is just what I needed.

    • Nice clock but pray you do not have to replace the battery.
Color: Black-red Led
Nice clock but essentially impossible if you need to replace battery. (Requires a jewelers screwdriver and considerable force/effort.) If the AC power goes out, the display blanks out but the battery keeps the time current.

This clock is perfect. It is small, the number are large and the display can be dimmed for a softer glow. I love it.

    • Power protection & auto setting are absent, & this also lacks a low battery or battery failure alert
Color: Black - Green Led
Sure, sure is for sure, but only in one respect, this clock is for sure an absolute piece of junk. No automatic time of day setting function, no automatic calendar or external signal based change between savings and standard times, no time setting preservation during a power interruption, with a battery properly installed, and no low battery power or battery failure/omission alert. As this familiar tale goes, You pay what you don't get for. Seemingly nonsense instructions state that once the clock is plugged in it will fast forward rapidly to the correct time. No such thing occurred. The PM indicator is not lit so it appears to have initiated at 12:00 am with no fast forwarding, just counting forward from there, as any non "AccuSet™" clock would. I don't have a paper clip, possibly the stripped metal end from a sandwich bag tie, to test if resetting might force a time scan. It does not. just sends the clock back to 12:00 (AM). In the basement, near the wi-fi, but Sharp never specifies how a time update is captured, so it seems correct to assume that it is the National Institute of Standards and Technology radio broadcast, something that never worked for my Casio watch here in New England, but I unplugged the unit, took it upstairs, set it at about shoulder height and plugged it in. The display briefly lit all numeral creating LEDs "18:88" (and the PM and Alarm on indicator LEDs also light up for that brief moment) then went back to 12:00 (am). This all LEDs light at power up, is the only auto or diagnostic function of any type that this clock performs, and only if the operator uses that moment to visually verify that all the LEDs are working. 12:00, this in itself is very disconcerting. I just simulated a power failure by unplugging the clock and then plugging it back in, several minutes had elapsed since I had let it set itself to 12:00 (am) in the basement, and yet when I plugged it in on the first floor, it also set itself back to 12:00. I used the bag tie again to activate the reset feature again, let the clock run for 2 minutes, displaying 12:02, unplugged it and took it back into the basement. When I plugged it back in, the display briefly went to 18:88, and then back to 12:00 (am). The battery is not providing time setting saving protection. It's all nonsense. Unplugged clock and removed battery compartment cover. There is a battery. I don't know if the clock has a display alert for a spent battery. I will remove the battery and test for a response. With the battery removed, plugging in the clock exhibits unchanged behavior. The display briefly shows 18:88, and then it goes back to 12:00 (am). It's an expletive dud, an expensive brick. This clock performs no added function with a battery and provides no alert if the battery fails or is omitted. Unplugged, returned battery and sealed the compartment. Plugged it back in. The DS(tandard or avings)T on/off switch can't have any relevance. It was set to on when I received this, and I left that alone, since I wanted the clock to manage this for me, but when it isn't even trying to receive outside intelligence to guide that action, it will obviously never know when daylight savings time is in effect. Operated that switch while the power was connected. It set the time back by one hour when switched to off, then returned one hour forward when set to on. If I set it to off, unplug the unit and then plug it back in, I'm predicting that the clock will reset itself to 12:00 (am - standard). Unplugged it. Switched DST off. Plugged it in. My presumption was correct. It displays 12:00 am now, not 11:00 (pm), and when I toggle the DST switch to on the time advance by 1 hour (1am), and returns by 1 hour when I shut it off. While this could have useful manual application in a clock that is marketed as non-automatic, it only adds to the uncertainty of a clock that is claimed to be intelligent but so far shows zero sign of being so. What happens if suddenly one day the clock receives a signal or if some supposed, but so far absent intelligence, attempts to kick in? The clock is obviously manufactured for sale in most of the Americas, with only Eastern, Central, Mountain and Pacific switch settings. While these are labeled: EST, CST, MST, and PST, that labeling is part of a society's lock on ignorance, just as the DST switch is. You can't know if your time is standard or daylight or predict that from a label on a switch and you can't accurately speak of or write of the specific nature of time if you lack daylight savings time, not just daylight standard time as part of your vocabulary, yet even during daylight SAVINGS time, everyone, all across the country, when they want to clarify that they are, or might be in a different time zone, state that they are on x (zone) standard time. They say this all through the summer, during which they are actually on x savings time. What idiot made it so that both terms used the same first initial, "S?" And why are we then such idiots that we can't remember that that S carries two very opposed meanings? We are as stupid with our connection to time as we would be if we were to cal Saturday and Sunday "S" day, and Tuesday and Thursday "T" day, and to forget that they were two different days and just, by whatever was popular regionally, call them both Tuesday: "Well which Tuesday do you mean," the more informed would always need to ask, "the Tuesday after Monday or the Tuesday after Wednesday?" Selecting DST to stand for Daylight Standard, or Daylight Savings Time, or for both, is just plain idiotic, stupidifying refuse. You need to use DStT or DSaT, and EStT or ESaT, just like you can't drop the U or the H from TU and TH. That would make America so much smarter, or to be smarter still, change "daylight" to "non-standard" and use "N" (DNT), or change "standard" to "normal" and that can be the DNT. Operating the E, C, M, P time zones switch does modify the time display by one added or subtracted hour per position, but without added intelligence, or backup, this is a superfluous "feature." ... show more

I like it because it has DST as well as small and two brightness to choose. It is light and small. Easy to handle. I purchased the one that has a green light and I like it very much.

    • VERY MISLEADING DESCRIPTION
Color: Black-red Led
The description of this clock is inaccurate and misleading. It gives you the impression that you will never need to set this clock as it will autoset as if it is an atomic clock that uses radio signals to set time. It is not. It's auto time setting feature simply means that they set the time on it before it left the factory, and as long as the internal battery back up works, it should arrive to you with the time set already. You just have to use some switches on the bottom to choose your time zone and whether DST is active or not. My unit arrived with a dead internal battery, so it was not set. Not a big deal as it is easy to set, but if the battery goes dead or if you hit the manual reset, you will need to reprogram the time. IT DOES NOT SET AUTOMATICALLY. It is simply an alarm clock with a battery backup that they programmed with the time in at the factory. Nothing special about the auto-set. Other than that, it seems to be a nice, simple alarm clock. I really wanted more of a true auto-setting clock (atomic clock), so I am not sure if I will keep this or not. ... show more
