I've had profound hearing loss since the age of 2. After years of my parents waking me up, I got my first Sonic Boom Alarm clock when I was in High School. I've had it for 12 years and it still works great! I bought this one because my old one was accidently packed up in storage while moving this summer. This new style is more compact and is more aesetically pleasing, but has the same great qualities that the Sonic Boom Alarm clock has always had! I've never known anyone that could sleep through this alarm! I use just the vibrating option as that wakes me up just fine...the lights are a bit too much for me.

Amazon Verified Purchase
I bought this for my wife who is a very heavy sleeper and who's actually lost a couple jobs from not being able to wake up in the morning in time. She's not deaf or anything, but she can totally sleep through a 'loud' alarm clock.
The buzzer:
I bought this based on the descriptions and other reviews of the several different models of this clock which made it sound very LOUD (wake the neighbors-type loud) which I hoped would be enough to startle her out of sleep. Unfortunately, this isn't noticeably louder than many other clocks I've had. My first impression of the buzzer was "That's IT?!" It has an adjustable tone which is neat, but still that doesn't make it any louder and only slightly more annoying. My wife wasn't impressed with the volume either. While adjusting it we didn't even have to really raise our voices over it to hear each other.
The vibrator:
This is the part that I'm counting on to wake her up. It's pretty strong and I'm surprised that something so small can shake so violently. If you put it in the pillow that you're using it's liable to cause brain damage after a while, but if you push your pillow more than a few inches away -or grab another pillow- it's useless. It works pretty good in between the mattress's though even though we have a pretty thick mattress on top. It won't rattle your teeth that way, but it should be enough to wake her up after just a minute or two.
The construction doesn't feel any better or worse than most clocks to me and it's easy enough to figure out how to set and use. I would have given it a higher star rating had it of just been louder.

Now this is one great clock. The first night I used it, I was about knocked out of bed, and I did not have the bed shaker even plugged in.
I like the large numbers so when I do wake up at night, I can clearly see what time it is.
When the alarm goes off, the lights start flashing, it is impossible not to pay attention to it.
I highly recommend this product.
