RCA RC571 Digital Alarm Clock Radio with Large Numbers and USB Charging, LED Display, Brightness Display, FM Radio with Presets, Dual Wake, Sleep Timer and Snooze Functions, Black

Amazing product. The Product is amazing as it has a big display where you can see the numbers. When I turn off the lights the display automatically knows to turn on a dim almost glow in the dark light. The snooze button is back and has a nice click feel to it. On top of that the alarm clock works on two AAA batteries and the third battery is back up. The sound of the alarm is very impressive as it starts with one beep then it turns into two beeps. After that it turns into three beeps and then it continuously makes loud noise until you wake up. One thing I hate about alarm clocks is setting them up. My old RCA I bought 10 years ago as a painter set up. This one is very easy as you have a master selector switch and then that controls the exact button and function. If you’d like to set the alarm you switch to alarm and then you can change the alarm Siri simple and took me 30 seconds to set it up. The added benefit is that it displays the temperature and it also displays the alarm time in the upper right hand corner and even the date it’s a very multi use clock and very well priced at $10 I will be buying another few for family and friends.

This clock is awesome. I looked at a lot before making a purchase, but I'm glad I decided on this one. Runs on batteries and is small enough to take anywhere. At night it's bright enough to read, but not too bright. I like it completely dark when I sleep and this doesn't bother me at all. Easy to set up and the temperature is an added bonus.

I really liked the simplicity of this alarm clock when I first got it. It has a light motion sensor, so it will dimly turn on the light if there’s movement. However, after a while, the light stayed on all the time and was disruptive to sleep. Now you can no longer see the numbers unless you tilt it a certain way. The first image is while looking straight at the clock, without the light on. The second is tilted at an angle, which is the only way you can view the time. The third and fourth photos are with the snooze light on. You get the gist. While not an overly expensive clock, save your money and go elsewhere.

This review is for the alarm clock, not the clock radio.The third AAA battery is not for backup, it's for lighting the display. When you hit the snooze button, the display comes on brightly. When you change one of the rear switches from Sensor Off to Sensor On, the display will stay on, if it's dark enough, nicely dimly.My clock is still new, so I can't say how long the third battery will last if you keep the clock switched to Sensor On. So I only turn it on when I need it.All I can say for sure is that it's a very nice display. I put this on my Ham Radio station and set the clock for Greenwich Mean Time, which is abbreviated in Sumerian as "UTC."I never set the alarm, because I was afraid it would tend to wake me up. zzzZzzUpdate: Dropping my rating from 5 stars to 4 stars. The clock runs fast, picks up a second every day. So every few days, I set it slow a few seconds.

This alarm clock has some issues. We have had two issues with this Alarm clock. The first is that I like to use the radio as the alarm instead of the buzzer option. This is great when it works. For some reason, without notice, the alarm will not go off when set to radio. The alarm light (dot) will be illuminated showing it is ready but when it is time for the alarm to go off the light is out/off even though the setting button/tab is still set in the correct position. It is an intermittent thing, so I do not know why it only happens every 4th or 5th time it needs to alarm. Luckily, it has a second alarm setting that you can set just in case the first alarm (if set to radio) decides to not work as a backup (make sure you set this to buzzer though). With that being said, just don't trust the radio option as the alarm. The second issue I have with this is the brightness of the display. It is pretty bright. Once your eyes adjust to the darkness of the bedroom, it really stands out. It was so bright, we made shadow puppets on the wall with how bright it was. We had some extra tinting film, so we covered the display to block/lower the brightness. This really helped. So, just be aware that this may be too bright for some.

VERY quiet alarm with no volume control. Nice, big, easy to read display. Displays the date numerically 5/16" high, 12 or 24 hr option time with big 1 1/2 inch numbers, alarm time (only one setting, not a dual alarm), and temp with option of °F or °C. Be sure to save the instructions, slightly tricky to set up the first time. Nice for a cheap clock, but very quiet alarm so probably would not wake you up unless you are a light sleeper. Works okay for me. The light sensor did not work on mine (can press the snooze button on the top to light up the display at night). The alarm only sounds 1 time for 1 minute (unless you hit the snooze button) and then will sound the next day at the set time unless the alarm is turned off. Uses 3 AAA batteries. Generally, I like the clock but only rated it as 3 stars because it is made in China and I think the alarm is much too quiet for most people.

easy set up

Radio itself is small with easy to read numbers at night. Radio part is loud and clear. USB port is nice to have to charge a cell phone at night. Eliminates an additional cord plugged into an outlet.
