Review: Amazing Product - BEfore buying this product I checked the product reviews to make sure everything was in order and found a few people were having problems keeping the time, I clicked on the comments page for one of these reviews and found that the cure is to set the thing on the back to 50Hz (if you are in the UK) as it's time-keeping comes from the electricity in the house (you plug it into the wall) and you have to set the thing on the back in accordance to the homes electric (UK = 50Hz)whereas setting this to 60Hz would mean the homes electric and the alarm clock settings didn't match (you'll understand what I mean when you buy this item. Anyway it's very loud and is guarenteed to wake you up, I wasn't sure what to expect from the vibrating attachment but was impressed, it vibrates furiously and if placed under your pillow is guarenteed to wake you, the volume of the thing and the vibration together is definately something you'll wake upto. It's easy to set time and alarm, easy to use the volume etc. I just want to say now this product does not require batteries, there is a slot for a 9V battery but it is not required, as I've said this alarm is powered by the homes electricity all the battery is for is a backup so if the homes electric cuts out or whatever then the alarm will be able to keep track of time, according to the instructions even if the electric was to cut out then the LED screen wouldn't show it would just keep time, if you ask me it's better just giving the battery a miss and re-setting the time when needing to (when unplugged or electricity cuts out)
Review: Love this alarm clock! (Using it with shaker pad only) - This alarm clock is great and just what I was looking for! I'm actually a very light sleeper, and didn't need a clock that is loud, but I wanted an alarm clock that can wake me up by vibration only. I'm hypersensitive to sound and when I set a regular alarm, for some reason I constantly believe I can hear it in the middle of the night and wake up, just to find that it's 2am or 3am or 4am or whatever, and no alarm going off. And when it actually goes off, I always find it way too loud, regardless of how quiet it really is. I wanted to see what happens with a shaker pad instead of sound, and the result is a much more relaxing sleep for me. I've stopped waking up in the middle of the night, hallucinating alarm clocks going off, and when the shaker pad goes off, it feels like a massage, yet it's impossible to sleep through it. The vibration is much stronger than I had anticipated, so I put it buried under a mattress and a mattress topper in the middle of the bed. The big numbers also mean that you can easily see the time at night. The snooze button is easy to reach. And I love how customisable it is! You can customise almost anything. The snooze duration, volume, tone (even though I don't use the last 2), the brightness of the display, ... You can also add a 9V battery in case there is a power outage - if the main power supply is cut, the battery is used as a backup power supply, so you won't oversleep, and you won't have to readjust everything. The display goes off while it's running on the battery, but everything else still works. And the display comes back on once the main power is back. The only thing that would make this even better is if you could set more alarms (even just 1 more would be enough), and adjust the days they are active on. E.g.: Alarm 1, Monday to Friday. Alarm 2, Saturday. Alarm 3, Wednesday. Otherwise you'll have to remember to turn your work alarm off Friday afternoon and turn it back on Sunday afternoon.

## Features

- EXTRA LOUD ALARM - With its 85dB loud alarm, the Sonic Bomb is the ideal alarm clock for people with hearing difficulties and heavy sleepers. If you are wondering how loud this alarm really is, think that the sound made by a hairdryer is usually measured at around 85dB as well.
- VIBRATION PAD - If the Sonic Bomb's alarm doesn't wake you up, its vibration pad surely will! Included with the product, this pad can be placed under your pillow or mattress, and vibrates when it is time for you to get out of bed.
- SNOOZE BUTTON - The Sonic Bomb has an adjustable 1 to 30 minute snooze, as well as a 1 to 59 minute alarm duration. Pressing on the alarm's large snooze button when it is ringing will mute the alarm and allow you to enjoy a few extra minutes of sleep… until you are eventually woken up again.
- 3 ALARM SETTINGS - Depending on what works best for you, have the Sonic Bomb wake you up with either both its alarm and flashing light, both its vibration pad and flashing light, or all three at the same time!
- BRIGHT RED DISPLAY - The bright red digits on the display will help you see easily what time of the day _ or night, it is. And if you worry the brightness might disturb your sleep, simply decrease it by pressing on the alarm's dimmer button, you can choose between 5 levels of brightness.

## Questions & Answers

**Q: How long does it ring**
A: It rings indefinitely until it is physically turned off.
I woke up earlier than the time it was set once, forgot about it went to work just to find out that it was on all day annoying other people in the house.

**Q: Does the alarm work on just battery power, i.e. when not plugged in to the mains?
Assuming battery is charged obviously......**
A: The battery is there just to maintain the time in case of a power failure but the alarm only works when it is plugged in.

**Q: What does alarm 1 do and what does alarm 2 do?  And why would you want both on.  How do you just set the d... alarm?**
A: You can set alarm 1 and alarm 2 to whatever you want, each one saves only a particular time, e.g. you can set alarm 1 to 08:00, and alarm 2 to 06:00. Most of the time you will want for only one to be active at a time, e.g. from Monday until Friday you leave alarm 1 on, but on Saturday, you turn on alarm 2. It just means you won't have to change the current alarm time and instead just flick a switch to use a second saved alarm time. It's then just another flick of a switch to use alarm 1 again. You can technically have both on at the same time, meaning the alarm would go off at 6am and then again at 8am, using the example above.

**Q: why does the description here say 85db?but the internet and manufacturer says 113db?**
A: Manufacturer says 113dB for this model, and since they perform the tests and have a reputation to protect, I would be inclined to believe them. Another piece of information worth noting is that the Camo version "Bunker Buster" boasts a 12V shaker - the black and red also has a 12V shaker. Looks like £20 for the Camo paint job.

### ⭐⭐⭐⭐⭐ AMAZING PRODUCT - FINALLY, I'M UP ON TIME!!!!
*by M***T on 23 October 2024*

I am a very light sleeper and the only way I can sleep is by using earplugs that block out most noise - obviously the problem is that it also blocks out most of the alarm clocks I use, including loud twin bell alarm clocks. Also, since I started taking blood pressure medication, I found that I have been sleeping much deeper and have a lot of problems waking up. Then someone recommended this alarm clock, and honestly, best purchase I've made this year. I know it's enough to wake the dead it's so loud, but it has me up on time and that is all I wanted. I actually didn't even need to use the bed shaker, but just grateful to have found something that finally wakes me up and is super loud - so very happy with the product and features. Took some adjusting to find the right volume for the buzzer, but there are different buzzer options, and you can dim the clock also, which I found useful - I have it on the lowest setting so the glare doesn't bother me in the night.
