AcuRite 75155M 14.5" Large Green LED Digital Clock Inch, Green

Bought this clock to put in a window to see the time in the backyard. Bright enough and large enough to see as far out as we can go. Good value.

I bought this clock in August to help my kids keep track of the time and date for cyber schooling. I wasn't sure how I'd like a blazing red LED institutional looking clock on my wall and I was a little concerned the light would overwhelm the room. I initially preferred blue, but the price was so much higher I went with red. I decided to go with Acu-Rite over an unknown brand because I have their hygrometer that still works great five years later. Turns out, we love the clock. The red is bright and has a nice, smooth glow, but doesn't burn your eyes or discolor the room. I can easily read it from two rooms over, so I can do chores and still make sure my kids are online at the right time. There was a problem, though. Just a little over a month after hanging it on my wall, I woke up in the morning and the display was completely black. I tried another outlet, which confirmed that the clock did not work. Since it was past the return date on Amazon, I went to Acu-Rite's website and chatted with a representative. (Currently, they only offer support through chat and email due to COVID.) While on chat, I provided my receipt and pictures, and THAT SAME DAY, they shipped out a replacement. Two days later I have a working clock before the start of a new school week! I hope this new clock works for years like my hygrometer. While I can't speak to the longevity of this unit, many people seem happy with theirs based on the high reviews, and at the very least, I can say that Acu-Rite stood behind their warranty and acted extremely quickly with respect to sending out a replacement.

I can't recommend this clock enough! I have to admit to being exceptionally pleased with it. It arrived exactly as I expected and is perfect for a home gym atmosphere. I mounted it high for wide visibility and it really set a great tone. The red color is nice and vibrant, not over powering but clearly visible from a wide angle and the picture attached is somewhat washed out (the color is more vibrant that it looks on camera). It was suuuper easy to program and I had it on, set, and mounted in 10 minutes. One note, and this is not a bad thing about it, but the battery compartment is strictly used in the event of power failure from the wall source. The clock display will go off, batteries don't keep it illuminated, but the settings and time are all kept current and resume when power is restored. So plug it in, put in the batteries, and disconnect the wall plug to mount it and there will be no issues with having to reset it. Overall for something as simple as a clock, I am really pleased and would definitely recommend it. Also, I didnt think the in room temperature reading would be useful, but since its in a home gym, it really is!!

Great clock! Bright and readable! Purchase for my husband’s garage. He loved it.

This display is large and very bright. Its easy to read from long distances. It was easy to hang with 2 screws and the included screw template was perfect. The button placement and cable management features are well thought out. I had some apprehension because some reviewers said it had really bad accuracy and the time drifted. I've run this one for two weeks now and while that's not very long, I'm not seeing any noticeable drift in the accuracy. Will update this post if I begin to see that issue. The only issues I have with the clock, and the reason for a 4-star review instead of 5, are two simple features that are missing: (1) The clock will ONLY do 12 hour format. It won't do 24-hour format. If this was explicitly stated in the description I missed it, and was really looking for it to do the 24-hour format. (2) There is no brightness adjustment. The clock is extremely bright and very easy to read, but in even slightly dark environments like operations centers or some offices it is too bright. It can be glaring to look at directly, and casts enough light that it illuminates the room and I don't even need to turn the lights on to walk to my console. I don't understand why there isn't a dimmer for this clock, not even a high - med - low button. (3) (Added 2020-09-18) This clock does not indicate when there has been a power failure; it will reset and continue reporting the [incorrect] time as though nothing had happened. No blinking numbers, no blinking colon, nothing. Update 2020-09-20: I discovered an important quirk about this clock. The clock requires power from the 5V 1.2A adapter to operate, although it also accepts 2 AA batteries for backup in the event of a power failure. During the power failure mode with batteries installed it will keep the time but with no display, and resume with the correct time after power is restored. That behavior was to be expected, but here is the important part: If the backup batteries are not installed and the clock loses power, once power is restored and the clock resets there is NO INDICATION that there was ever a power outage. I had a power flash at approximately 2300 one evening, and I was halfway through the next day before I realized that the clock was an hour fast. The power blip had reset the clock but there was no way to tell that anything was wrong without comparing it to another reference source. Even a $5 wal-mart alarm clock will blink to let you know that the power was interrupted. So if you get this clock, be certain to install and maintain the backup batteries or a power outage may cause the clock to start lying to you.

DO NOT WASTE YOUR MONEY ON THIS CLOCK! ONE OF IT'S MAIN PROBLEMS THIS CLOCK STARTS TO HAVE IS THAT IT WILL FALL BEHIND ON TELLING THE CORRECT TIME. THIS STARTED THE 1ST YEAR WE HAD THE CLOCK. IT BECAME FRUSTRATING TO CONSTANTLY CLIMB UP THE LADDER UNHINGE THE CLOCK FROM THE WALL ONLY TO HELP IT CORRECT THE TIME. WE REALLY DIDN'T THINK AT FIRST THE PROBLEM WOULD GET WORSE BUT IT DID. DECEMBER 17, 2021 IS WHEN WE PURCHASED THIS SO-CALLED REPUTABLE BRAND FOR $47.99 FROM AMAZON AND AS OF TODAY FEBUARY 22, 2026 ( 4 YEARS AND 2 MONTHS ) IT NOW FALLS BEHIND 5 MINUTES! I HAVE HAD IT WITH THIS PROBLEM AND REPLACED IT WITH ANOTHER BRAND THAT WE HAD IN ANOTHER ROOM GOING STRONG WITHOUT ANY PROBLEMS 4 PLUS YEARS! WISH I COULD GET MY MONEY BACK SINCE THIS CLOCK NEVER GAVE ME THE SECURITY OF DISPLAYING THE CORRECT TIME!

very good

I bought this around 10 months back and it’s still running strong. The battery helps for the backups. It has an auto light feature that dims to ensure I have a nice sleeping experience. If you need, you can always get the dimming stickers and stick it to the display to further better your experience. Anyways, it’s a good product, no complaints so far! 🧿

Buon prodotto si vede molto bene la numerazione un bel rosso acceso peccato però non fa le 24 ore ma solo le 12.. in più tocca munirsi di adattatore spina dato che arriva con l attacco spina europeo tipo inglese

I put it in my bedroom but I couldn’t reduce the bright it’s to much for a bed room

compare varios modelos de reloj digital para el hogar y este para mi gusto es el mejor, ya que tiene brillo automático cuando oscurece baja la intensidad del brillo y lógicamente cuando hay luz de día aumenta el mismo. con este ya son tres reloj de este modelo y marca y le doy 10 de 10 , pareciera que tiene un costo algo alto comparado con otros modelos y marcas pero vale la pena la inversión
