DreamSky 15.5" Large Digital Wall Clock with Jumbo Big LED Number Display, Auto DST, Date, Indoor Temperature, 12/24H, Plug in Digital Clock Wall Mounted for Home Office Garage Warehouse Shop

Without my glasses I can't see my hand in front of my face. I was do tired of when I would wake in the middle of the night I would have to search for my glasses to see what time it was. Not any more. This close is bold and bright and actually also replaces a night light as it provides enough light to walk thru the room without turning on the lights. Reasonably priced. GREAT PURCHASE!!!!!

Update 19 Apr 2020: I finally found a reason to order another one of these, this time in blue. I wanted to run the power cable through stick-on plastic conduit (see my picture of the blue clock). The cable was far too short for this so I cobbled together a longer power supply.I used a SoulBay power supply (https://smile.amazon.com/gp/product/B01N7RS0NG) with the included terminal tip along with a 10’ extension cable (https://smile.amazon.com/gp/product/B081CTVY5Z). I cut the end off the DreamSky power cable (leaving about 3” of cable) and connected it to the terminal tip (which is attached to the extension cable). The wire with the white stripe is positive so that gets connected to the positive terminal.Once I connected the DreamSky tip to the new power supply (via the terminal tip and extension cable) I switched the power supply to 9V and plugged it into the wall. Before powering the clock I double-checked the voltage and polarity with a multimeter. The end of the extension cable and terminal tip did fit in the extra large compartment thoughtfully provided by DreamSky but just barely.I’m just as happy with the blue clock as I am with the red one. I don’t know why I love these clocks so much but they make me happy. No, I’m not being compensated for my review, I’m just weird lolUpdate 13 Jan 2020: The clock has worked flawlessly for the last year. It adjusted from standard time to DST and back again on the correct dates. It's been unplugged a couple of times but the backup batteries (not included) did their job. Finally, it's still as gloriously bright as the day it arrived on my doorstep.Original review: I'm tired of clock mechanisms breaking in analog clocks so I decided to go digital. I wasn't sure what I would get when I ordered this clock. The photoshopped product pictures showed red numbers (and a clock that appears to be 4-6' across) but the customer pictures were of an LCD clock. I'm happy to report that the numbers are red...bright red. The clock is perfect in my garage (which is why the walls are all beat up in the picture I uploaded).The manual is missing a few details. Pushing the "up" button switches between 12- and 24- hour mode. Pushing the "down" button switches between Fahrenheit and Celsius. These functions are on the buttons themselves but hard to see (small raised black text on black buttons). I've never seen drywall anchors like those included. Presumably a hole needs to be drilled first because they can't be hammered directly into drywall (trust me on this). I ended up using a drywall anchor I had on hand.I'm very happy with this clock and think it's a good value. The clock is all numbers which is exactly what I wanted...I don't care to waste space on decorative nonsense. The numbers are large and bright...have I said "bright" enough yet?I'm willing to bet someone will ask so here's the answer: no, the numbers don't dim. Why would you want to dim such a gloriously bright clock?P.S. Backup batteries not included.

The time display is huge, 4.25 inches. It is extra bright, not dimmable. The whole unit is 14.5 x 1.5 x 5.3 inches. It can be mounted on the wall or set up with the stand. It comes with a cardboard measuring ruler with the hole positions marked for easy wall installation. Smaller daylight savings time (DST) indicator on left upper corner with AM/PM. Automatically changes to DST when turned on. Has month number and day number, plus inside temp on the right upper corner of display. Not as large as clock time but very legible. Has battery backup, 2AAA batteries not included. Power outage it will keep the settings but screen will be blank. AC power cord is about 6 ft.

I like the large letters and uncluttered display. Love that I can glance over and quickly get the time even while on the dreadmill. Exactly what I needed.If I had a wish, it would be autosetting of the time. (I really wish manufacturers would start using GPS instead of NIST time radio as I get a really weak signal here.) But so far the time is pretty accurate. I've not had to correct it in the time I've had it.100% recommend.

First, I included a picture simply to give you a visual sense of scale. I'm not sure who provided the "official" pics Amazon is using, but they make the clock appear way larger than it actually is despite the true size being clearly indicated in the product description.Anywhoo... The clock is easy to set, and I really like the green LEDs (looks washed out in my picture, but they are in fact very vibrant). It has a DST function, but I wish it was a physical switch instead of having to go through the programming cycle. It came with a little cardboard template for positioning the mounting screws, which was appreciated. It also has a spacious compartment next to the battery slots for storing any excess length of power cord you might have, which was also appreciated.What did annoy me, and which was ultimately why I couldn't give this clock 5 stars, is that you MUST have 2 AAA batteries installed if you want any sort of power protection. Now, I get the need for battery backup with an electronic clock. That this clock can't hold time across even the briefest of power outages without a battery is sad. C'mon people. Spring for a frigg'n capacitor so my clock can survive a half-second brownout event.UPDATE: I take back what I said about the DST function. I had assumed you had to manually toggle daylight savings, which would have been easier with a physical switch. Apparently, I had not understood that this clock automatically accounts for it if DST is "on." So, when I went into my shop today (Nov 1, 2020), the time was correct without me having to do anything. Nice.

Great quality

I purchased an different product that offered a larger display for less money, this underperformed by comparison

Worth the product and it is functioning seemlessly

This product does not come with a UK plug nor does it come with any adapter. As such you cannot use this product in the UK. I contacted the seller and I told them I could not use this product and asked them to supply a plug adapter but they said they don’t have one and don’t know where I can get one. So why are they selling this product in the UK. If you live in the UK then avoid avoid avoid!!!!
