DreamSky Digital Alarm Clock with Battery Backup, 5 Inch Large Display, Auto Set Clock, USB Charging Ports, 12/24H

I spent hours over many days during 6 week sorting through available clocks on Amazon and other sites. Initially I passed this up due to a lower than average review rating. However decided to give it a try and ended up ordering 3 more. Now have a total of five. Will update review if they fail.Have had thee clocks now for 2-3 weeks. Set up was impressive! After the first two arrived, I was so blown away, that I ordered 3 more.After unpacking, I inserted 3 AAA batteries in a couple (and not in others) and plugged in. I did not have to set any time! It set itself automatically on my time zone. That met my most important need. We live where thunderstorms take down our power for a few minutes to a few hours a few times every month, sometimes weekly. Occasionally lose power for a day or more. It drives my husband and I crazy having to reset clocks so frequently.We have a few critical clock needs- large font, ability to dim at night, able to display time during power outages and ability to have the clocks display the correct time automatically when power comes back online.Unbelievable that no one makes such a product! Unless it's battery powered only. So when I finally gave in and looked at "battery" clocks, this one popped up. "Battery only" clocks are too small for our needs as they are mostly designed for travel and when not backlit, are hard to read. Battery clocks just can't put out the wattage needed for a bright, year round display. So I kept searching for a clock that plugs into the wall and had an option for batteries to keep time during power losses.This clock plugs into the wall and works both with and without batteries. When power goes out, if batteries are inserted then the clock face is able to display all readings when the Light/Snooze button is tapped. It displays for about 30 seconds. Very helpful if power goes out in the middle of the night and you are wondering what time it is. It also displays a "low battery" icon when they need to be replaced. We put one in the garage with batteries and another in the guest bedroom. The other 2 are in a family room and game room and they didn't need batteries as we don't use those rooms when we lose power.When power is resumed the clocks all display correct time, no need to reset. Of note, the clocks may have a 1-2 minute variance of displayed time but for us, that isn't an issue. Any clock we manually set, also has that same varience. Should an exact time be needed, we have mobile phones and tablets. The six inch high display, is absolutely perfect! Aging eyes need more space between characters. This clock has a good 1/4" space from all the edges and 1/2" between hours and minutes. The time is displayed 2 inches high on the upper two-thirds of the screen. This thoughtful elevation makes it easier to view than a smaller 2-3" clock when propped up in bed reading or laying down because it's at eye level.The 2" white font is easier on our eyes than our previous 2" red LED clock displays.We keep the Bright setting (5 levels) on high for the all the clocks except for the ones in our bedroom and guest room. Those are kept on Auto Bright which means it self dims to the lowest setting between the hours of 9pm to 7am and then retuns to the high setting. The minor drawback is that when the power goes out (even with batteries inserted) the clocks will default to the highest Bright setting, so the Auto setting needs to reset. The purpose of the batteries seem to be soley the ability to see all the displays (time, temp, humidity, battery level, time zone, day, date, am/pm, moon phase) when the Light/Snooze button is pressed.A huge unexpected plus for us with this clock is the built in Day, Date, Temperature and Humidity displays. Being retired, we are used to minor confusion of the days which are tracked mostly because of medical apts. Seeing the day and date helps us become centered when awakening. Living in FL the temp and humidity are quite useful as well.The clock size is perfect. Not too small to be easily knocked over accidentally or knocked off when cleaning the table top. It's lightweight to pick up when dusting and easy to grasp. The base is firm and keeps the clock on its placed location. The body design doesn't accumulate dust on the back. The power cord is long enough to reach nearby outlets from a table top.While not designed as a "travel clock"' should we have to travel, I would definitely pack one of these in our suitcase! So often we have to unplug hotel clocks due to too much night time brightness, alarms going off in wee morning hours and not displaying the correct time. This clock displays the Time Zone (EST, CST, est.) which is so needed when traveling! Not to mention the temp display which helps with decisions over hotel thermostat adjustments. It's so very difficult to locate and read those wall thermostats without a flashlight and glasses. Another travel plus is having the extra USB at our bedside.Our order for a generator install at this new home has been held up for 5 months due to shortages of propane tanks. However, these clocks will still be very much needed as the generator doesn't kick in until we have a 2-3 min loss of power. (A safety/compatibility issue with the tie in to our electricity provider to ensure its a true power loss and not a flicker situation.) Very pleased to have the correct time displayed regardless of power loss or flicker.My one reservation is if they will hold up over time. A handful of older reviews said they gave out after a few months. If that happens I will update this review.

Wow!!! I can't believe all the bells and whistles on this alarm! It provides diming light, room temperature, date, day of the week., largerTime display, and will show what time my alarm is set for. and it even has an up-and-downOption for setting the alarm time. ⏰️ alarms have come a long way! You will not be disappointed. Oh, and did I mention if the power goes out there is a battery back up option!!!

This us a lovely clock. Numbers are larger enough to see without my glasses. very east to set up You just need to choose your time zone. The alarm is pleasant starting off slow and increasing and the tone is something I can hear. Good price too.

Why did you pick this product vs others?:I picked this item because I was replacing an alarm clock that was no longer functioning. Interestingly enough, two years ago I ordered this same clock and that clock is still working. I wanted a matching clock so I went to my previous orders and selected the same clock I had ordered previously by clicking on the link. What I didn't realize was that, in spite of it being listed as the same item, the current version is smaller. This wasn't a deal breaker for me so I kept it but was amazed by the "sneaky" production of the manufacturer to simply make the item smaller but with same product name and description.Functionality:I only have one plug beside my bed and was looking for a clock, phone charger, and wanted to have a thermometer as well.

Bought two of these. They sync to an over-the-air time server, so they both should display the same time, but only one displayed time correctly. After several months, the other became consistently two minutes fast. I contacted the company for help, and they replaced the defective clock, even though it was nearly two years old.

Its simple to set up and use. It has USB charging ports. Easy to read. You can easily dim the digital display. If you're retired like me, you don't always know what day it is. When you wake up in the morning the clock, tells you the day, date, temperature, and the time you set the alarm for.

arrived on time, in new condition. A compact size. Big Bright numbers. Easy to set up. The alarm is quick to set. An improvement from my last clock. Would recommend it.

Love this clock in the orange! Subtle and works great. I’m too good at cancelling my phone alarm so hoping this forces me to get out of bed and walk across the room. Snooze on top of the clock and press any button on back of the clock to stop the alarm until the following day.
