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

I have literally NEVER slept through this alarm
I work swing shifts so I am constantly having to move my hours of sleep around and it used to make me over sleep and be late to work which was such a big problem I almost got fired over it. However I did some light research and found this amazing product that borders on self inflicted abuse. However I couldn't live without this thing. The clock itself is a good shape that is stylish and appealing and the screen is plenty bright for casual use. Then there are its 3 different methods of waking you up. 1 the classic siren. Its loud as hell and has a volume adjustment dial in case you wanted it louder for some reason. 2 a strobe light, a row of bright LEDs that will strobe the room when the alarm triggers. 3, the most powerful of them all is the vibrating pad, that is to be placed under your pillow and will violently vibrate your head to wake you up. This is the perfect thing for me because no matter how tired I am, if I need to get up, this thing will get me up. Even better I have become confident that this alarm will get me up which relieved my anxiety of oversleeping which allowed me to get better sleep overall.
