Loud Alarm Clock with Bed Shaker for Heavy Sleeper, Dual Vibrating Alarm Clock with USB Charger for Hearing-impaired Deaf, 7.5’’ Large LED Display with Dimmer, Snooze, 12/24H & Battery Backup

My 10-year old vibrating alarm clock stopped working. I shopped around and bought this one. I seldom write reviews. But I am so satisfied that I'd like to share my experience with everybody.I hope that the manufacturer reads reviews, as I'll mention one thing that I hope they can take into consideration when they design their next model in the future.Pros:1. This alarm clock uses two AAA batteries as back-up during power outage. AAA batteries are cheaper and less bulky tnan 9V battries that my old alarm clock used to use.2. The display is bigger and brighter than my old alarm clock's display.3. I really like the DST function. It works like this: You first set the clock time to your local Standard Time. Then in March when DST begins, you push the DST button. It adds one hour ("springs forward") to the clock time. In November when DST ends, you push the DST button again. It subtracts one hour ("falls back"). There is a small indicator on the screen to tell you if it is in DST mode.I wish that the DST function can be automated. But I imagine that it'll make the cost higher. At this price point, I am happy enough with this simple button.4. It has two alarm buttons ("Alarm 1" and "Alarm 2") so that you can set two different alarm times. I only need one to wake me up in the morning. But some people may find the second alarm time useful.5. The vibrator works as advertised. It shakes me out of my bed. I don't use the ringer. So, I can't comment on that.Cons:1. There are two buttons, "Alarm Pause" and "Alarm Off". When the alarm goes off in the morning, you press "Alarm Pause" to stop the alarm for the day. It will go off again tomorrow morning. If you press "Alarm Off", it turns off the alarm completely. That is, the alarm won't go off until you turn it back on by pressing some other button. So far, so good.Here is the problem: These two buttons are right next to each other. So, in the morning, the alarm goes off, you get out of the bed, still kinda sleepy, you want to press the "Alarm Pause" button to stop the alarm. But if your finger slips and presses the "Alarm Off" button by mistake, then you'll wake up the next morning 2 hours late, wondering why the alarm didn't go off.My suggestion to the manufacturer: When you design your next model, consider relocating the "Alarm Off" button to an entirely different place. I'd suggest move it to the right side, next to the "Ring/Vib" button.I still give this product 5 stars, because I consider this shortcoming quite minor. I'll simply make the habit of checking the "Alarm On" indicator on the display every night before I go to sleep.

Plenty loud. Wakes up a deep sleeper. Bed shaker didn’t work.Update…seller made the issue right.

This clock was great. It didn't take a lot of time to figure out how to work it; it took hardly any time at all to set up. It was just as loud as the other clocks I've tried, but the vibrating rumble device is what sets it apart for me -- it made a HUGE difference when it came to waking me up! The other alarm clocks I tried, I just slept through the alarms. The rumble is just the extra bit of noise and rattling I need to wake up. I put the rumbler on my shelf where it would really rattle and make a ton of extra noise.HOWEVER, it broke after a year and three months. It WAS a great alarm clock, I loved it. First, the rumble device stopped working. Which was disappointing, but the clock itself was still good. BUT, a couple of weeks later, half the display went dark. Another week later, the entire display went dark. It still makes noise every morning but I can no longer set the time. I never dropped it, jolted it, smashed it, it just sat on my bookshelf. Kind of a bummer because this clock was great, but alas, not everything is made to last.P.S. -- I never used it to read the time, just as a morning alarm, so I can't speak to whether it's good as a clock. I will say, though, the numbers were VERY bright at night, enough to dimly illuminate my room -- if you prefer a dimmer clock, you might not like this. I personally didn't mind it.

I am a cochlear implant wearer and have to take them off at night meaning I am fully 100% deaf when I sleep. This alarm is so great. The shaker doesn't work under the mattress because its not strong enough but it works great under the pillow. I put mine under the pillow and inside the case so it doesn't go anywhere. It wakes me up every morning. There are options of shaker and sound, and I like to only have the shaker on so I don't wake up anyone else in the house. Definetly buying this for when I go to University and have to move into a shared dorm.

Great clock!! I keep the buzzer on my end table and it wakes me up fast!! Only negative is the snooze button and Vibration/Buzz buttons are next to each other. I accidentally hit the buzz button and it turns off the vibration… make sure to hit the snooze only!

As someone who can sleep through every alarm, this is perfect. There is absolutely no way you could sleep through this monstrosity. The traditional alarm clock is a great alternative to my phone, and unlike my phone cannot accidentally be set on silent or fall off the charger. I like the option to set two different alarms I can toggle on and off, as well as the ability to toggle between having an audible, vibrating, or both alarm types go off. It's perfect for heavy sleepers who may have roommates. I found sticking the vibrating disk under my mattress or zip tying it to my bed frame was most effective to keep half asleep me from unplugging or throwing it away from my bed.
