4This will wake you upFeb 25, 2010
By Matthew C. Clodfelter "Halfy"
I've had a history of sleeping through alarm clocks. This past summer I lived with a few other people and they would come into my room in the morning and yell at me, because my old alarm would wake them up but I would sleep through it, despite the fact that it was positioned right next to my head.

While I do not believe this alarm reaches 113 decibels or that it is louder than a jackhammer, I will say that it is much louder than your standard alarm clock. The vibrator works very well and is guaranteed to wake up even the deepest of sleepers. You can put it under your mattress, which will cause the majority of it to vibrate, or you can place it against a solid object which will cause a loud vibrating noise. I opted to keep mine under my mattress.

Many people have posted that their units burned out or that it kept time incorrectly. This is because they failed to look at the directions. In the directions that come with the alarm clock there is information detailing a switch on the backside of the unit. It is labeled 24hrs 50hz, 12hrs 50hz, and 12hrs 60hz. This switch not only controls the time format(12 hour vs. 24 hour), but also controls the tuning of the internal electronics. In European countries, 24 hour time format is standard, and wall outlets alternating current runs at a frequency of 50hz. In America, most people use the 12 hour time format, and our electrical outlets operate at a frequency of 60hz. What this means is that if you have this switch in the wrong position, you run the chance of damaging your unit, and you will notice that the time will not be accurate(it says this in the manual).

The only thing that keeps this alarm from getting five stars is the face that I can't use the 24 hour time format. I live in the US but work on a military base and have become accustomed to the 24 hour time format.

tldr; This alarm will wake you up, just make sure to read the manual or you run the risk of incorrect time and a fried alarm clock.

5Sledge-Hammer Alarm SubstituteMar 15, 2008
By Hoosiermama
I was desperate to find an alarm that would wake me up in the morning. I joked with my husband about finding one that has a sledge-hammer to clock me in the head, because I just couldn't wake up in the morning.

I was setting an alarm clock, my cell phone clock, and having my husband calling on his way to work and I was sleeping through all of it!

I found this on Amazon and I am astounded at how well it works. The disk goes right under the mattress and it literally vibrates (in bursts) the whole bed. It's not what it sounds's not going to collapse the bed or damage anything...the disk is the size of a large hockey puck and is self contained in it's vibration. The decibel level of the alarm, although doesn't seem much different from other unique in its tone and pitch. It has a louder and "stronger" sound (if that make sense). The lights, to me, are unnecessary, because between the shaking and the alarm, it's enough to wake me up.

The only problem is that it has a snooze button! So, I'll get jolted awake, smack the snooze button, and fall right back asleep. However, that's my problem...not the alarm.

A great alarm for people who have a hard time waking up to a Traditional Alarm Clock.

Highly recommended!

5Craziest Alarm EverSep 04, 2011
By Lag Man
Five-star device with three-star instructions. Got it as gift for my heavy-sleeping 20 year old whose job starts as early as 4 AM. He said it would not keep the correct time. I asked him if he read the instructions. He assured me that he knew how to use it. I tried setting it myself with the same result--the time was off by next morning. I was ready to ship it back, but decided to follow my own advice and read the instructions. Turns out there is a power cycle button on the back of the device that is country specific. It was on the UK setting. I switched it to the USA 60 Hz setting and it works just fine. Why that would not be prominently placed in the user guide is a mystery to me. Why my son does not yet take my advice is a mystery to me.

As for the alarm, it is the only one that has ever reliably awakened my son. I would rate it as scary loud and the vibration disc provides tactile stimulus to further provoke consciousness. I can hear it in the basement from my upstairs bedroom.

5Great alarm clock for waking sound sleepers!Oct 01, 2011
By C. S. Cox "old movie buff"
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!

5Sonic bombDec 09, 2007
By Rebekah
This is a good clock. While it can be loud, the volume can be adjusted for those who do not want to have a heart attack when they wake up. The bed shaker does a good job of waking you up too. If you sleep like a rock this is a good buy.
