I have literally NEVER slept through this alarm

- Reviewed in the United States on July 14, 2017Color: Black & RedVerified PurchaseI'm usually not one to do reviews but this certainly deserves a review!!!
We've had this about 5 months now.. life changing!
Hard sleeper? Hitting the snooze button a lot in the morning?
Yeah..well, that’s me..it hasn’t always been… Heck, I used to be up by 5 AM every morning, ready to kick booty and take names. Well, not so much these days. Not sure if it's because I haven’t had a full night’s rest since 2012 (thanks Al’s) or because my diet & exercise have turned to crap-- nonetheless, Russians attacking the U.S. in broad daylight couldn’t wake me from a midday power nap if given the chance.
Being business owner, WAHM, Wifey.. Surely you can see how that can be an issue.
As fate would have it, Mr. Smo and I happened across this surreptitious alarm clock marketed towards those that sleep like a railroad tie instead of a normal human being should. Literally never heard of it. The ad promised to wake the heaviest of sleepers. I’m thinking, “they’ve obviously not met me, so..”
What the heck, let’s give this thing a whirl. We buy it. It comes in 5-7 business days, yada yada. Of course I’m testing it out! I ain’t fixin’ to DIE trying to come out of my sleep (if it really works, that is!)
Firstly it comes to you literally looking like a bomb wire to a hockey puck. Like, that probably should have been my first clue to walk away. Nope, I’m a glutton for punishment.
Y’ALL- we were testing--- I repeat, TESTING this alarm, broad daylight… Not sleeping…Heck, we were expecting the thing to go off in a minute’s time. That alarm went off and y’all, If I’m lyin’ I’m dyin! I dang near fell out.. I nearly had a HEART ATTACK! This thing packs a whopping 113 decibels, (the same as a chainsaw, so you imagine one starting up as your alarm clock!) My ears probably bled lol..The vibration was jolting, but more on that later.
Alright, now to the real test:
So Night #1: Side note: Both Mr. Smo and I have a love affair with our snooze buttons. We usually set the alarms 1-2 hours ahead so we can snooze and “drift lightly back to consciousness in time” for the day. Night #1 we decide we’re gonna be some daredevils. Set that joker for the exact wakeup time. Let’s do it. We placed the “jolter-majig” under our mattress, in the middle, to make it fair for all parties.
I wasn’t ready. He wasn’t ready. Also, might I add, tiny Smo, too, was also not ready.
Now, let’s break this down. You’re sleeping. You’re dreaming. Then you get the “jolt”, and by “jolt”, I mean sit straight up in bed, bug eyed, scrambling for glasses, screaming across the king size bed, “HOLY !)@*# IS THAT AN EARTHQUAKE?!?” kind of jolt. The bed-shaker (that actually goes underneath your pillow, I do NOT recommend that) shakes so violently, you can hear and feel it on the other side of the house. So, yes, it literally shakes your lazy tail outta bed. Imagine a guy coming into your room each morning with a jack hammer, and that’s about it.
Then, you get the “squall”... (is that a good word? I feel like that’s a good word.) Remember the aforementioned 113 decibels? Try going from sleeping soundly, to a chainsaw in your ear with no warning. Your heart rate will go from 60 to 130 in seconds, from the first jolt, really.
Now, this God-given, Satan inspired gift also has one more trick… it has LIGHTS, as if the brutal awareness that you are no longer asleep, but may now have an anxiety attack instead, isn’t enough. I wouldn’t go as far as to say these red-flashing lights would cause a seizure, but it probably would be good to keep in mind if you have epilepsy. The only way I can describe these lights is, if you’ve ever seen flashing red lights on an ambulance, that’s about what it’s like.
The only experience Mr. Smo says he can compare this alarm clock to is being jolted to consciousness each morning in basic training. Like drill sergeants, the shear volume of this alarm clock will make it impossible for one to ignore it. Really, I’m not even sure why they included a snooze button on this thing.
If you have heart issues, do not get this. If you suffer from anxiety, do not get this. Epileptic much?-- probably not for you. This alarm is no joke. But it’s EFFECTIVE. I often find myself waking up before the alarm even goes off due to what I believe is almost fear. Imagine someone putting a jack hammer to your bed and the loudest alarm you can imagine going off. If you can sleep through this then you may want to go see a doctor to check and see if you’re still in the land of the living. Though, I’m certain no matter what state of decomposition one is in, it’d probably still wake the dead.
As far as wiring issues, not working, etc... no problems so far.
- Reviewed in the United States on June 16, 2025Color: RedVerified PurchaseA great alarm clock! Especially for those of us who are on heavy sleepers. I love the fact that it has a little shock attachment that you can run from the clock and place over underneath your pillow. I have to be up at 0500 most mornings for work so this definitely helps me get out of bed. The only negative part about it is that resetting it is a little bit of a pain in my butt. I like to sleep in a bit on Saturdays and Sundays so of course I get up later on those days. It’s easy to set the time a little bit later for those weekend mornings. However, when I have to go back to my early morning wake up morning hours on Mondays I have to sit there and hold in the alarm buttons and cycle back through the entire time cycle to go back to my 0500 alarm times. It’s a slight inconvenience and a bit annoying. But given the fact that the clock does such a good job of actually waking me up the rest of the week, I’m OK with it.
- Reviewed in the United States on July 1, 2025Color: PinkVerified PurchaseI have slept through every alarm clock I have ever acquired… until I tried this sonic boom alarm. It actually wakes me up and I love that you can change the tone and the volume and customize,the snooze time. I also like the fact that there are two alarms. It’s a nice piece of mind for me because I’ve definitely reached over and stopped my alarms in the past that only had a single alarm setting.
I was a little skeptical in the beginning because like I said, I’ve never had an alarm that actually woke me up, but I would suggest giving this product a try. If it works for me, it’s probably gonna work for you too.
- Reviewed in the United States on May 12, 2025Color: Black & RedVerified PurchaseI have two of these, both had the vibrator break off the cable, I would normally shove it to the bottom side of a pillow and it worked well, sometimes even when it got pushed against the wall it was loud just vibrating and woke me up.
For Loud and vibrations, it's alright, I can't really say how to improve the vibration aspect, the cable could be braided and nicer perhaps? It is annoying to change alarm times but if you don't need to often it's totally serviceable, and with a battery it has lasted through power loss for me.
Even without the vibrator, they are loud and do the job haha.
I once slept with my window open, and woke up to the police asking me if I was ok through it, it was so loud the neigbors knocked on the door and called them after. I was just THAT tired I suppose, but good to be aware of, use where it may not irritate people.
- Reviewed in the United States on June 10, 2025This is a great clock. I am hearing impaired and cannot hear a darn thing without my hearing aids, so I need the bed vibrator. I've always relied on the Sonic Bomb brands, and chose this one since the other I usually like is no longer available.
The vibration works strongly under the mattress, the sounds are loud and I can adjust the tones that I hear it without my hearing aids (I keep it off so not to bother my neighbors).
If you don't like the vibrations or the sounds, the bright flashing lights will certainly have you up and out of bed in seconds.
I like that you have the option of which mode to wake you. Lights, sound, vibration- or all three or mix of three.
I do recommend this clock, and I hope it lasts 10+ years like my previous ones.
- Reviewed in the United States on June 4, 2025Teen boys are hard to wake up. The Sonic Bomb just might work.
It was simple to follow the instructions for setting. The buttons and toggles are clearly marked.
The snooze can be adjusted for the amount of time of your choice.
It has the option to set two alarms.
The light display can be adjusted from very dim to super bright.
The cord for the vibrating attachment is fairly long; reaches from nightstand to middle of a full bed with plenty of slack.
The alarm sound has a wide volume range. The highest is VERY loud.
To our delight, the vibration is wide spread - not just a little spot. We put it under his two inch mattress topper and it can be felt in a very large area and pretty intensely too. If it was just the vibration, he might enjoy it like a massage LOL but the alarm is killer.

5.0 out of 5 stars Prefect for heavy sleepers . It will wake you up
Color: Black & RedVerified PurchaseI’m a heavy sleeper and had a few days where I slept through my alarms . I decided I needed to take action to prevent this from becoming a trend . This alarm was my action and it worked . The alarm is very loud in sound , the included vibration pad will shake you awake, it is so powerful and the flashing light will make you jump out of bed thinking your house is on fire . It will wake you up no problem . I have since that time got married and my wife has banned this alarm from our room with the agreement she will kick we awake .
Perfect alarm for heavy sleepers .

Útil para personas con sueño súper profundo, estoy muy satisfecha con la compra, ojalá tenga un buen tiempo de vida útil, se puede ajustar el volumen según las necesidades, el aditamento de vibración también funciona bien y no es una vibración violenta. Tengo colección de despertadores, finalmente encontré el ideal
