  • Its EXACTLY what is described... I sleep like a rock - this is the only thing that will wake me up!!
Color: Red
This Sharp Big Band Super Loud Alarm Clock - is the real deal. It isn't a normal loud, it is EXTREMELY LOUD! Which is exactly what I wanted and needed! It has different wake up sounds and has I think 1-15 different loud settings, 15 being the loudest. If your anything like myself (I would call myself a very, very, HARD sleeper, anything above "10" will work for me) but I still have it all the way up just so I know ill wake up regardless! It's a blessing and a curse to be able to sleep like I do, but the curse is that normal alarm clocks just don't do it! I even looked into those alarm clocks with a shaker for your pillow.. I can tell you with how loud this is, you don't need anything else but this alarm clock! To give you a little example of how deep of a sleeper I am, when my fiancé and myself were in the hospital after our third child, the fire alarm for the brand new hospital we were in, went off and everyone on our floor ran out of their room thinking if was for real, and this was around 3AM in the winter, there was snow on the ground outside - I was still sleeping on the bed completely unfazed from this gigantic alarm going off through the hospital. Yes I was a bit sleep deprived as well but still, even if I wasn't, I would not have woken up.. So after saying that type of story, and for me to say this works for me should tell you how loud this alarm clock is!! I will say if your sharing a house with roommates, small kids, or a family - you may want to let them hear it so they at least don't awaken frightfully when it goes off lol regardless where this alarm is located in your house, it WILL wake up people throughout the house if you have to have it on the loudest setting. My fiancé can literally wake up to her phone vibrating in the morning. She is a very light sleeper so if she was around in the morning to hear this alarm clock go off it would probably blow her eardrums out (lol being a little dramatic but it is extremely loud when your right next to it) but really this is so loud it will wake some up everyone in the house. In all seriousness this alarm clock does its job for HEAVY SLEEPERS and is a fantastic!! I have loved it since the first morning Ive used it. It has not let me down yet and I HIGHLY recommend this alarm clock to the people that sleep similarly to myself. 5 out of 5 stars for this product! Love it!! ... show more

  • Beep beep beep, time to click Buy Now
Color: Silver
Why do you need an alarm clock in the age of smartphones? Sometimes your smartphone goes dead overnight and doesn't wake you up in time to get to work on time. Enter the loudest alarm clock I have ever heard in my life. It's got great features and it's easy to set. There's a variety of different tones, but I prefer the standard beeping tone. I could set it loud enough to wake everyone in the house, but I don't need to start a war with my neighbors. I haven't missed my alarm since I got this. What else do you need to know? ... show more

  • LOUD. NO MORE MISSING WORK.
Color: Silver
This alarm is LOUD. So many alarms claim to be loud and can’t even wake up my dog. This alarm is genuinely loud. I would talk about other things but let’s be real we are here cause we’ve been late to work and don’t want to be fired 🤣🤣 10/10 worth the money.

  • Good little clock
Color: Silver
Clock is super loud! Looks good large numbers.the only issue is if you don't hit snooze the alarm will turn off after a couple minutes, kinda defeats the purpose but I'm always up. Just one thing I would watch out for if you think you may sleep through this one! Super loud

  • Amazing alarm very very very loud
Color: Red
Five stars 10 out of 10 normally I’m a really heavy sleeper. Nothing wakes me up but this alarm if you get it, I would recommend the siren alarm but if you have people in your house, sleep with the door shut and the volume on 10 otherwise everyone in the house is gonna wake up lol I learned this the hard way🥲 but I would definitely recommend for the very heavy sleeper. If you’re a light sleeper, you’re probably gonna get a headache. ... show more

  • Great for heavy sleepers
Color: Red
Great alarm for me since I’m a heavy sleeper. The only thing I have noticed is that some times it does not go off or it goes off for a few seconds and then stops

  • Works well for its target user.
Color: Silver
This is the best alarm clock for heavy sleepers. The volume range is impressive. It also has a variety of alarm sounds that all get one's attention. Easy to program.

  • loud and lots of options
Color: Silver
Impressed at how loud it is. Not only can you pick from alarm sounds, but you can also change the pitch/ tone of each sound. Volume is adjustable. Does it get the teenager out of bed with its loud obnoxious noise? Not my teenager, but definately not due to any fault of the alarm clock. This thing impressed me. The most comprehensive obnoxious one I've seen yet. ... show more
