Sonic Bomb Dual Extra Loud Alarm Clock with Bed Shaker, Black | Sonic Alert Vibrating Alarm Clock Heavy Sleepers, Battery Backup | Wake with a Shake

I bought the Sonic Alert Sonic Boom dual alarm because I’m a very heavy sleeper, and this alarm absolutely does what it’s designed to do. The alarm is extremely loud and impossible to ignore. Even on a lower volume setting, it’s still very effective. The dual alarm feature is really helpful. I can set two separate alarms, which is great for different wake-up times or as a backup to make sure I don’t oversleep. The bed shaker is another big plus — it’s strong enough to wake me up immediately and works well when placed under the mattress. The buttons and display are straightforward and easy to use, and the large numbers are easy to read, even from across the room. Setup was simple, and once set, the alarms are consistent and reliable. Overall, this alarm is perfect for heavy sleepers or anyone who struggles to wake up with standard alarms. It’s loud, effective, and well worth it for peace of mind.

This clock is getting rather mixed reviews and I was a little worried when I bought my first one about a year ago. I bought it for my son, who was a senior in high school. He slept through all of the alarms that I bought at Wal-mart for him. He would then be late (or not go) to school and the principal would call me to ask where he was. (I swear the principal had me on speed dial!) After I gave my son this alarm he never slept through his alarm again. He did leave school early on numerous occasions (and the principal kept me on speed dial) but an alarm clock can only do so much at helping with parenting. (He graduated, thank God, and uses the alarm to wake-up for work now.) My son's alarm has worked perfectly since the day it arrived, so I had no qualms in deciding to buy one for myself last April. I am hard-of-hearing and I like the vibrating disc that goes under my mattress. It wakes me up right away. I don't even put on the noise--just the vibrator. It works great! It has gained 2 minutes in 5 months. I think people should READ THE DIRECTIONS and set the switch on the back for USA electric currents! My son-in-law and daughter sleep through their alarms all the time--even when they have 2 or 3 of them set! I gave them my Sonic Bomb alarm clock 3 days ago and he has woke up on time every day since! That is why I am purchasing my third one today. I need another one for me. These alarm clocks are great and I highly recommend them to heavy sleepers, hard-of-hearing, or even profoundly deaf people. There are some features the clock has that are not mentioned in the description of the clock: 1) It has battery back-up--so when the electric goes out (ours goes out about 15 times a year) the clock still keeps time. 2) The alarm has the ability to be on just noise--really loud annoying beeping, which can be adjusted for loudness and tone (for hard-of-hearing people who hear some tones and not others)Or you can put it on just vibrate--for people like me who don't like to wake-up with adrenaline pumping through my body. Or you can really juice it up by putting on the noise AND vibrate your bed, which my son and son-in-law both use to wake-up. 3)It also has flashing red lights that go off when the alarm does to help people wake-up. I do not have anything bad to say about the clock. I highly recommend buying one. Just make sure to read the directions pertaining to the switch on the back about setting it for which country you will be using it in. August 9, 2012 Update: All 3 of our alarms are still working great! February 9, 2014 Update: All 3 still working fantastic! The best alarms we have ever owned! August 19, 2021 Update: My alarm is still working great!! Keeps great time and the vibrator is still functioning perfectly!! Wakes me up everytime. I assume my married kids' alarms that I gave them are still working or they would have asked me where to buy a new one, Lol

We finally found a product to help us wake everyone (in the house) up in the morning. I ultimately bought this for my wife (who is legally deaf) because when she is sleeping, it is unbelievably difficult to wake her up enough that she does not just immediately just roll over and go right back to sleep. If you're looking for something for someone you know like this (hearing impaired or not) you know what a difficult time it is go get them up and moving. I needed something that would motivate her into moving and actually 'wake her up'. Well, this item does the job. Even in the most sound sleep, the vibrating alarm feature does the trick. It literally shakes the floor as well as the whole bed making this alarm impossible to ignore. Ever other alarm I have tried in over 20+ years really never did the job. Mainly the "ignore factor" for every other alarm clock did nothing to actually get her up and moving. With this device, there is the very loud noise factor which is great for everyone, but besides the audible alarm and the vibrating puck under the mattress, there is a bank of lights that flash which adds to the alarm as a whole in making sure it wakes everyone (in the whole house, no matter where they are). Also, I should note that the cord to the vibrator unit (we put under the mattress) is completely suitable to placing the alarm away from the face of the person sleeping. Even on low, the light from the digital display is still bright enough to keep anyone that does not sleep with a sleep mask on, awake. I put the clock portion about 3+ feet away from the bed, on the other side of the night table so it absolutely wakes her up. She has to get up out of bed to turn off the alarm (plus, avoid the stampede), which makes her angry as a hornet, but it gets her up and moving (which was the whole point of this alarm). "Everyone up!" I should note that with this alarm, she is up and moving in less than 4 seconds. OK, it is mainly to get out of the way of a stampede of big dogs she has encircling her, all jumping up, trying to avoid whatever it is shaking the bed loose from the floor. I have actually gotten up earlier than everyone on numerous occasions, just to watch what happens when the alarm goes off, just to watch the stampede and the ensuing turmoil. It is good to find a product that fits a niche (like I have at home) as well as it is always good to have something happen in the first moments of the morning (a stampede of dogs for example) to make it a great start to the day (at least for me). NOTE: Test this device with 'everyone' (that lives in the house) around 'before' you use it for the first time. For the first couple days you use this, make sure no one panics. The first day, everyone thought this was a fire alarm going off and the jolt of the vibrating puck added to the confusion. I highly recommend that you test it a couple time (so everyone in the house can hear what the alarm sounds like) to make sure no one thinks there is a fire. This alarm could 'possibly' be confused with the alarm sound of a home fire alarm. I recommend you have everyone go to their own bedrooms and allow the alarm to go off (a couple of times?) to get them used to the alarm sound. Hey, this thing can be heard throughout my entire house when it goes off and it did cause a panic the first morning it went off. We had kids with flashlights and fire extinguishers coming from all directions that first day. I am just glad no one called 911 and had the fire department show up. I would not want to be on the local news as "Family calls 911, Fire department responds to family's new alarm clock, news at 11" or whatever. This is pretty close to what happened. Plan ahead if you get this!

Deaf purchaser - Must Read the directions. Great waking options to choose from. Strong bed shaker vibration (I placed between mattress and box spring just under my shoulder region) but not so strong that it scares you awake. The optional flashing yellow lights are perfect. They are just the right color to not hurt your eyes when you open them from deep sleep. I found the combo of the flashing lights and bed shaker are just enough to pleasantly wake me, not JOLT me out of a deep sleep. Similar to someone gently rocking your shoulder & asking nicely to wake, not screaming at you while jumping on the bed. Visibility: The dimmable red digits are best for not interfering with sleep. Readability: Extremely small font size for the settings. I have to don the reading glasses to read them. I am sure after a few more uses that I will remember which buttons do what and will not need to wear my magnifiers. Quality: Functions are excellent quality. Plastic feels a bit cheap/thin which may pose a problem of cracking if the alarm is dropped. Recommendation: YES NOTE: I have a elderly dog that is aurally and light sensitive who sleeps in his own bed in my room. This alarm wakes him up but does not scare him. (I imagine it would traumatize him if I used the sound as I read it's very loud.)

I don't usually write reviews but this clock is amazing. First of all it's so loud that I don't need the flashing lights or the vibrator. But most of all when you look at the direction page it is overwhelming but when you take it step by step, it is so easy to perform any of the operations! Just love this!

Ever since I got my C-PAP several months ago, I've been sleeping like the dead. By which I mean that I sleep through all of my phone's alarms, which used to wake me up from my fitful, cruddy (lack of) sleep. That entire setup is your first clue, dear reader, that I am old. I am an old man who does not like waking up in the mornings. Mornings suck. If I ever hit the lottery, I will wake no earlier than nine in the morning. The early bird gets the worm, you say? Yes. Well, the second mouse gets the cheese. On the plus side, these days I wake feeling refreshed--like I actually slept. On the downside, sleeping through my alarms wasn't great for that sucky part of adult life called "employment." My boss is somewhat forgiving, but she's not going to change my start time to, "Whenever this guy shuffles in on any given weekday." Trust me. I've tried. She's not having it. So, I ordered an alarm clock that I figured would do the trick. This little gizmo. With the lights and alarms and vibrations. If it's been awhile since you've set a digital alarm--one that isn't your cell phone, I mean--you may need to read the included instructions. I know I did. (I TOLD YOU I'm old. Sit down, young'uns, while I tell you the terrifying tale of Growing Up Without WiFi. Oooh, spooky!) The directions helpfully explained what all the buttons do, and when, and how to make this alarm clock do what you want it to do. Overall, setup was quick and easy, including turning on the alarms I'd just set. Then I tested the alarm. Holy. Cow. Am I glad there's a way to adjust the volume on this thing. I had it set too high for the test run. It wasn't like my face melted or anything like that--this alarm does NOT go up to 11--but it was close. My wife was downstairs and she heard this alarm over the TV. A neighbor who happened to be outside wondered if I'd gotten a new kitchen timer. Somebody from NASA contacted me to say that somebody on the International Space Station had requested that I shut that thing off already. Nifty features: * I can set two alarms. Because sometimes, I just want to turn off the first one and lie in bed for awhile. It's nice to have the second go off to tell me that, no, I really do need to drag my butt out of bed and do work-type stuff. * The display brightness is dimmable, in case you care about the glowing-red numbers interfering with your sleep. * Bright, pulsing lights that, despite being very effective on me, do not in fact wake the dead. (I'm qualified to say this, as I live near a cemetery and, so far, no undead visitors complaining about their eternal slumber being disturbed.) * A plastic disc to put between the box spring and top mattress. Do you sleep on your back? FREE BUTT MASSAGE AT "NO THIS IS TOO EARLY" AM. Do you sleep on your side? Sorry about your bruised ribs. Do you sleep on your stomach? Don't. Just...don't. The power of the vibrating disc will bruise your navel. Fortunately, most of these features are optional. I can tell the alarm to not bother with the flashing lights, and I can skip the Vibrating Disc O' Doom. However, I usually need one or both of these options, so I keep them on and accept the fact that I will be startled awake five days a week. As for my statement that this alarm works "most of the time." When I have to take a full dose of Benadryl, this alarm doesn't work. This is why I can't take the full dose. If I sleep through this ridiculous, loud, vibrating, flashing monstrosity of an introduction to the morning, I will sleep through literal axe murderers making their way through the house at full volume. And nobody needs that in their lives, especially first thing Monday morning. Buy this alarm if you really need to be awake at a specific time. Five stars because the alarm clock did not come with the Benadryl and, therefore, cannot be blamed for that unfortunate situation.

I love this alarm clock. It replaced the same previous one that finally died after many years. I’m totally deaf so I really only the vibration to wake me and it does. I have it beneath a thick mattress and it works great. When I have heard it with my processors on (cochlear implants) , I really it is very loud. Combined with the flashing lights, it would wake a dead per. You can turn the modes off so you don’t have to have all 3,going if you don’t want to

I read a review before purchasing. A woman had a teenager who wouldn't wake up & sleeps like the dead. Ditto! She said this clock has been great. My son has probably been tardy 30 times this school year so I took a chance. It went off for the first time this morning. I laughed so hard it was so loud. The cord for the vibrating piece wasn't long enough to reach the bed but we didn't want the clock on his nightstand. We put it on a bookshelf out of arms length. The vibrating piece was almost louder on the shelf that the actual alarm but boy did he jump out of bed immediately. I highly recommend this clock!
