Review: Best clock I’ve ever owned! Great for seniors! - I’m 65, and don’t really get along with technology. But this clock is perfect for seniors. I plugged the clock in and it knew the date, time and everything, ease of use is great . I dims itself at 9:01 Pm and brightens at 7:00Am. It’s as basic functionally to operate as any clock gets. I set the alarm for 6:00am, it beeps and I press any button on the back to turn off the alarm (not the snooze button). I don’t have to mess with it after that. It’s automatically set for the next day. The display size is large. The value for the money is great, too. I put in batteries in so if the power goes off, it will save the information. Not sure about the battery life yet since I haven’t owned it for very long. I WOULD ENCOURAGE ANY SENIOR TO BUY THIS CLOCK!
Review: Best Clock Ever - This is the cutest clock. We have it on my husband’s side of the bed on his bedside table and he loves that he can turn the display down very low at night. He can still see it but it’s not so bright it keeps us from sleeping. It also has the date and temp. Another plus is that it came already set. It has battery backup. If you’re looking for a great little clock that is so very easy to use and easy to see with brightness or dimmer this is the clock. It’s small but the display is large.

## Features

## Questions & Answers

**Q: Is the time supposed to set automatically?**
A: Yes, but it will always set it 2-3 minutes slow. Even if you manually adjust it, it will reset itself slow again within days.

**Q: Does the auto dst icon only come on after the 2nd sunday in march?**
A: This is not an atomic clock and the description is misleading. The clock has a watch-like CR-2032 behind the regular AA batteries that keeps the time, but the time has to be set manually. The description says it's auto set, but this is a lie. If you take the CR-2032 battery out and put it again, time will reset to 12:00 and it will never auto set to the right time again, you have to do it manually. The time on the clock when you first received it, it's whatever time it was set at the factory, it will never auto set to the perfect time since this is not an atomic clock. Also, even if you do set manually, there is no way to set the seconds, thus, the clock will never show the perfect time, you will always have at least a minute of difference.

**Q: What is the small cord with tiny end on backside of clock?**
A: The clock is electric, it is a USB cord that goes into a plug that goes into the outlet.

**Q: What is the warrranty information**
A: Seller warranty: One year free replacement.

### ⭐⭐⭐⭐⭐ Easy to use and looks great.
*by J***G on January 16, 2026*

Great clock with so many features. Love how it lowers the brightness automatically and has the room temperature showing on it’s face as well as showing the alarm time setting. I didn’t even need a new clock but this was a great choice for a reasonable price. Well made and easy to use.
