Digital Alarm Clock with Keyboard Style Controls, Battery Back-up, Easy to Use with Simple Operation, Black Case with Red LED Display

I was looking for a simple, reliable, small alarm clock and this clock from Sharp fits the bill perfectly! Can’t half see well in the morning and the red digital readout is very bright. Works like a charm. Definitely well worth the money.

After putting the batteries in the clock, it took about 5 minutes to have it set. The clock plugs in to 110V power, but the batteries retain clock settings if you unplug it to move it. Setting it is very simple and straightforward, including the alarm. The LED display has 3 brightness levels, so you can have it bright enough to see in full daylight and dim enough to let you sleep in a dark room. The alarm is a buzzer and is pretty loud. The clock does not keep track of days, so you can set the alarm a maximum of 24 hours in advance. The clock is a simple, functional product at a very low price.

great small clock-takes up less space on my nigt stand-easy to set-I can see it from across the room. Definitely recommend!

I have been using this alarm clock for probably around a year now. It is super easy to use, which is exactly what I was looking for. It is also very reliable, which is obviously an important characteristic of an alarm clock. I like that the clock uses red numbers, as I have found that some clocks with blue light can keep me awake. I find that the display is bright enough to see in the day but not too bright at night. I only have two small complaints which contributed to the 4-star rating. First, I find that the alarm sound itself is rather loud and there is no way to turn down the volume. I have tried putting tape on the bottom in an attempt to muffle the sound, but it's still a bit much. I live in a condo with a shared wall, so I am probably more mindful of the noise than most people who live in standard houses would be. Secondly, the clock slowly loses time. I do not know if this is a problem with just my clock or not, but every so often (maybe once a month) I have to add a minute or two to the clock's time. It's not a big deal, but a minor grievance nonetheless. Overall, I would recommend this product if you are looking for something simple and easy without all the bells and whistles that come on so many modern alarm clocks.

I was looking for a simple desk clock that runs of AC and uses the 60 Hz mains frequency as a time base. The reason for the latter is because the electricity company keeps this really accurate, you will never have to correct the clock (as is often the case with clocks having an internal quartz reference). Quartz based clocks always drifts over time, not so for this clock. Also, those atomic clocks (as an alternative) were not an option for me, as the NIST radio signal for that (from Ft Collins, CO) is too weak where I live. Apart from the fact that those clocks cost at least twice as much. There is a battery backup in this clock that keeps an internal oscillator running when there is a power outage, two AAA batteries can be placed in the clock for that. Contrary what some reviewers have reported as a "defect", these batteries are only there to keep the internal oscillator running during an outage so you won't have to re-adjust the clock after a power outage. These batteries will NOT keep the display illuminated. That is not why these batteries are there, even the video reviewer had not grasped that fact I noticed. I recommend to use old-fashioned carbon-zinc batteries for this backup function, as alkaline-based batteries always start to leak corrosive electrolyte after a while. This will destroy your radio in the process. This leakage happens even when alkaline batteries are hardly used I have noticed, they are terrible in that aspect. Use carbon-zinc instead (often called "heavy duty" batteries) This is in fact my only gripe about this radio, it should have been designed for a lithium coin cell battery instead of the two AAA batteries. Lithium batteries never leak an have an extremely low self discharge. Another nice-to-have would have been a daylight- saving time switch, but not a big deal. Adding it all up, this is a buy I can recommend. The clock is built well and has good brightness (settable by the user)

Just what I was looking for. Great Quality. Bright Numbers. Easy to use. No instructions needed. Noise level is Loud.

Smaller than expected but I like the compact size. The traditional easiest controls ever. Great backup alarm for the other side of the room to ensure maximum chance of waking up. Thanks.

Simple interface, good tactile buttons, dimmable display, loud alarm. Good all around value for $10. But the power transformer hums so loud that it’s absolutely impossible to sleep with. Might be fine for some people but not me.

I bought this thinking it would work because why wouldn’t a simple alarm clock work in 110v-220v areas? Well it doesn’t. Only works in 110v. I tried batteries only. Nope. Be warned!

Had to return it as it came with US fittings but the clock itself looked quality.

Despertador de ótima qualidade, marca as horas com exatidão pequeno e lindo.!!!!

I wanted an electric alarm clock, just that, an electric alarm clock. I didn't want all the added stuff. Finally found this one and really like it. I've had it for 2 months and have had no problems with it. The alarm is loud enough, the numbers have 3 levels of brightness, it is easy to set. Just a simple, electric alarm clock which is difficult to find these days.

Muy bueno, se siente de buen material y es muy simple de configurar, muy bien👌🏻
