Game changer
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!

It is LOUD at OPTIONAL highest setting
I love how simple this alarm clock is. And when they say it's loud. I have it in my living room and it wakes me up from my sleep in my room. I like that the loudness is adjustable for each sounds option. It's been great for me. I also have it on a window ledge where it sits plugged in but also has batteries just in case the electricity goes out.

Great LOUD Alarm Clock but use FRESH batteries
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 👍🏻.

buyer beware
Very disappointed. I have bought 2 of these . If there was a "0" rating I would use it. The first one I bought failed when I plugged the power connector to the rear of the clock. The pin that was supposed to connect pushed back into the clock. No way to open this sealed case to attempt a fix. I bought this because I am hard of hearing and liked the loud variety of alarms but the second one I bought failed in a different way. After about 3 months the digital numerals started to fade piece meal. The brightness adjustment did nothing. Now parts of the numerals are completely unreadable. This is such a good idea with little attention paid quality.

The best option!
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.

Loud and should work to get your out of bed
We needed a loud and obnoxious alarm for my 16 year old son and this alarm is definitely loud and does work better to wake my teenager up. Teenagers are teenagers obviously and won't get up no matter what except for video games but this alarm clock is good and loud. It's good quality and should do the trick to get you out of bed

As a person with hearing problems this clock is perfect. Nice and loud, easy to operate plus the blue lit clock can be toned down so it doesn't glare in the room while sleeping. Highly recommended.

Loud as hell. It works exactly as advertised.

It worked daily, until 3 months, then the rooster would no longer crow, or make noise. So not a great alarm clock anymore. Plugged back in the 12 year old slow dying clock which still wakes me up.
