The three volume levels on this Screaming Meanie alarm clock can be best described as loud, louder, and loudest, topping out at a whopping 120 decibels (the volume of an ambulance siren). The travel-friendly clock runs on one 9-volt battery and fits easily in your carry-on, ensuring you'll never miss your wake-up call. Shoppers joke that this alarm clock is nearly loud enough to "wake the dead." One wrote: "Not only does the Screaming Meanie get me out of bed in a split second, but we are running to get it turned off ASAP. It is painfully loud and does the job quite effectively."

If you have a serious problem sleeping through your alarm, this little retro alarm clock is for you. Because it doesn't have a snooze button, you'll be forced to either shut the alarm off completely and risk oversleeping or learn to wake up with the alarm. Plus, it doesn't have an annoying ticking sound like other vintage clocks, so you won't be kept awake at night. "I'm a heavy sleeper… I've had firetrucks, ambulances, and police cars in my front yard and slept through it," said one customer. "This alarm scares me every morning, but it sure does get me awake."

At just $14, this simple Travelwey alarm clock is one of the most affordable options on this list. It's super popular among heavy sleepers, many of whom say it's loud enough to make it hard to sleep through. "There are two speakers on either side of the display that blast ear-piercing alarm noises for five minutes to ensure you wake up," one shopper said. Customers also love that the snooze button doubles as a way to turn on and off the nightlight. And thanks to the simple buttons on the back, it's very easy to set alarms and change the time.

If you can't stop yourself from hitting the snooze button, this cute wheeled alarm clock is an easy solution. After just one snooze, it rolls and leaps off nightstands (up to 3 feet high) while beeping random patterns—and it hides until you hunt it down. It's safe to say you won't be catching any z's catching this clock. Even though plenty of adults in the reviews section have found success waking up with this alarm clock, many say it helps their kids get out of bed in the morning, too. "I bought this for my teen daughter who sleeps through everything," wrote a shopper. "This alarm seems to do the trick [by] getting her out of bed and searching for her Clocky to turn it off."

With the iLuv Time Shaker alarm clock, you really get the best of both worlds: a vibrating bed shaker to jolt you out of bed in the morning and a charging station to make sure your devices have a full battery by the time you wake up. It features a Qi-certified wireless charging pad on top of the clock and a USB port that allows you to charge your watch or headphones at the same time. One customer with a hearing impairment said that the shaker is so strong, "there is no way you can sleep through the alarm."

In order to shut off this loud alarm clock, you have to actually get out of bed and stand on the rug for three seconds. But if you find yourself cheating your alarm by crawling back into bed after those few seconds, you can extend the alarm to require you to stand for up to 30 seconds—you'll be much more awake once the blood starts flowing to the other parts of your body. For more advanced alarm options (like the ability to upload your own .mp3 files), just plug the clock into your computer. "It does exactly what it says it will, and I am faithfully now up every morning at 5:30 a.m. bright and early with no issues," wrote a shopper.

You might find it easier to wake up to sounds that you want to listen to—and that's why the Echo Show 5 is the best smart alarm clock for heavy sleepers. With the help of Amazon Alexa, you can set it to wake you up to your favorite song, a radio station, and even some celebrity voices. In addition to the fully customizable alarm options, you'll also get access to all of the other features on the device, like instant updates on the weather and the ability to set reminders. Shoppers love that the volume gradually increases, and many appreciate that they can set recurring alarms and skip days if needed. "I think it is pretty cool that I can watch the daily news briefing on my alarm clock," one person wrote.

Amazon reviewers rave about how minimalist and lightweight it is, and many people love how easy it is to use. "I love this clock; simple with no frills," said a shopper. "I've had mine for several years and I recently bought one for my 80-year-old mother."
