Game changer

Krislynn LandryJanuary 13, 2026

This is the best alarm clock ive ever purchased! When i say, Its able to wake me up i can almost guarantee it gonna wake anyone else up that purchases one also! Its well worth the money! Before purchasing this i have always had the hardest time waking up with an alarm clock! I used to have to set several different alarms with several different sounds in hopes that one of them would wake me up but most times i wouldn't. I would sleep right through all of them because none of them were ever loud enough! THIS ONE HAS BEEN A GAME CHANGER FOR ME! I was surprised with how loud this one is and all the different options it has to choose from! All of which work amazingly well! It's actually able to wake me up the very first time it goes off each morning. What makes this one stand out even more is its not only loud but you can you choose different sounds along with being able to change the tone of each one of the sounds and also change the volume level of each one!

Extremely loud, easy to set, best alarm ever.

Curtis Dale WattsDecember 19, 2025

Ink impressed by how loud this alarm is. I replaced my "Sonic alarm bed Shaker" with this item. It has several different tones to choose from. Easy to operate didn't even look at the instructions. Im truly shocked at how great this alarm is. I'm a very deep sleeper. Read more

Great LOUD Alarm Clock but use FRESH batteries

Jon MageOctober 15, 2023

After 7 years, I finally got my dream job. I have been late for work one time in the last 5 years however, unlike my last job the first year at my new company if I am one minute late, I am terminated. You can see how important a reliable LOUD alarm clock would be especially because I am constantly switching from day shift to night shift so there is zero sleep pattern. While I still have my iPhone, iPad, and regular alarm clocks as backup this one has worked great the last 3 months! It’s a very loud/annoying alarm clock, the only problem I have is I used semi decent batteries in it and it failed to keep my alarms and time during a power outage, luckily my backup phone woke me up. Put a fresh battery in it and have tested it numerous times by unplugging it and that seems to have been the culprit. Overall still 5 stars bc it’s the best loudest one out there I’ve seen besides the Screaming Meanie, but this one is AC not solely batteries so 👍🏻. Read more

Very loud!

Carolyn BOctober 20, 2025

We are trying to teach our 15 year old grandson to get up on his own. He sleeps so hard that when he wakes up it is like he is coming out of general anesthesia, I am not kidding. This is super loud and does a great job waking him up. The reason I can’t give 5 stars is because it turns off after a few minutes- that defeats the purpose. He knows that all he has to do is lay there for awhile and can fall back to sleep. Fortunately he uses the second alarm, but still - it should not turn off until he turns it off. Read more

The best option!

StruthJanuary 13, 2026

I’ve had it a few weeks and so-far so-good. Ii can sleep through just about anything and my iPhone just wasn’t doing the trick anymore. I didn’t want a clock that just had obnoxious siren or beeping sounds that makes you start your day all irritated, so I finally settled on this one. It has the beeps and sirens but it also has a bugle, a rooster and an obnoxious mother type yelling at you to get up. The only thing that concerns me a bit is that the buttons to turn off the alarms sit to the ends of the snooze button so you have to be conscious enough not to hit the stop button instead of the snooze button. Looks wise it’s pretty compact and cute. I got the red one even though I don’t like red but this is a darker red rather that a bright red so I actually like it and the red makes it easier to find when I’m still 90% asleep. All these extra loud clocks are the same decibel wise so the alarm options was the deciding factor. I’m very happy with it so far. Read more

Its EXACTLY what is described... I sleep like a rock - this is the only thing that will wake me up!!

Sean G.November 24, 2024

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!! Read more
