There is essentially no way you’ll be able to oversleep when using this Sonic Alert alarm clock, which combines extra-loud beeping with pulsating lights and a bed shaker to get you up and moving. The 12-volt bed shaker can be placed under your pillow, fitted sheet, or mattress to vibrate your bed at a preprogrammed time. This alarm clock blares up to an impressive 113 decibels (which is basically as loud as a live rock show, to give you a frame of reference) while flashing lights at you. If that seems a little intense for your liking, though, the volume and tone are both adjustable, and you can even set the volume to zero. Those who are hard of hearing may really benefit from the vibration and light functions.

Amazon reviewers report that this pick has made a world of a difference when it comes to waking up. They give the alarm an overall rating of 4.6 stars on the site, among more than 22,000 reviews.

This alarm clock boasts a customizable snooze time, as well as a battery backup in case anything happens with the electricity. Choose from a range of clock colors.

Enthusiastic Amazon review: “This alarm is no joke. I often find myself waking up before the alarm even goes off due to what I believe is almost fear. Imagine someone putting a jackhammer to your bed and the loudest alarm you can imagine going off. If you can sleep through this then you may not be alive.”

If being jolted awake by a loud alarm clock doesn’t seem like the ideal way to start your day, it may be worth trying a totally different approach. This Philips alarm clock uses a light lamp to simulate a sunrise; over the course of 30 minutes, your bedroom will gradually be filled with a bright yellow light, so you wake up naturally. According to the manufacturer, Philips wake-up lights are clinically proven to help you wake up more refreshed.

If this sounds a little too good to be true, take the word of the Amazon reviewers who’ve tried it; with more than 10,000 reviews on the site and a 4.4-star rating overall, this pick has transformed the way many people wake up.

This pick has a built-in speaker that can play five different wake-up sounds or even FM radio if you prefer. And the light can be adjusted; choose from 10 brightness settings. Plus, this pick comes with a 90-day money-back guarantee.

Enthusiastic Amazon review: “Overall, I love this thing! It really works, though nothing will ever be as good as actually waking up to the sun coming in. This is a particularly important tool to have if you suffer from Seasonal Affective Disorder (SAD) or have blackout curtains because you work midnight shifts, or maybe you're just not a morning person. Waking up to a nature sound is a nice touch too.”

The brainchild of an MIT alum who scored a Shark Tank deal, the genius Clocky alarm clock literally requires you to get on your feet. When it’s time to wake up, the clock will run away, hide, and roll, forcing you to get out of bed and catch it in order to turn it off. The alarm itself is super loud. And reviewers on Amazon say the sound is unique; it’s like a robot meets an alarm clock. The clock also flashes lights as it leads you in a chase. Sure, the whole thing may be slightly (okay, very) annoying, but it definitely works.

Once you catch Clocky, you can snooze (the snooze time is adjustable from one to eight minutes), but at that point, you’ll probably be so awake that you won't even need it. The alarm clock works on all surfaces — carpet included — and is battery operated. Choose from a range of alarm clock colors.

Enthusiastic Amazon review: "I immediately went searching for an alarm clock that would force me to get out of bed to turn it off. This alarm clock does not disappoint. It has a customizable snooze time, and the beeps are slightly different every morning which means I cannot get used to a particular sound over time. It does also flashlights so if you are sensitive to that, you may want to look elsewhere as I don't know of a way to turn that particular feature off. Some reviews say that it can jump off a space up to 3 feet high, but I have never tested that so I just set it on the floor in a different spot each night. It is not smart enough to go around objects so it will keep backing up and running into the same thing if you have stuff on the floor. Overall, this has been a fantastic choice and I would highly recommend it.”

If you’re the type of person who simply snoozes because you can, it’s time to go back to basics with this retro-style analog alarm clock. The alarm clock simply removes the option to snooze, which means you actually need to turn off the alarm and get up in the morning, rather than delaying the inevitable. The alarm itself packs a serious punch, with a loud ringing sound that will wake even the deepest sleepers. Unlike some other analog clocks, the hands on this one are designed to move silently, which means you’ll actually get some sleep at night so you can be well-rested in the morning — plus it has a convenient backlight that lights up the clock face when pressed but goes dark when released, so you can’t ruin your rest by leaving the light on.

The clock comes in six different colors, any of which would look fantastic on your nightstand.

Enthusiastic Amazon review: “I specifically bought this to put in my teenagers' room because waking her up in the morning has become a constant battle and challenge. After trying multiple alarm clocks that claimed to be the loudest, I can honestly say this one’s a winner and wakes her up every time. ….To the point she’s tried to hide it from me a few times.”

This Sharp digital alarm clock is fairly standard, except for the ascending alarm feature, which starts off with slow quiet beeps that get louder and more frequent the longer you wait to turn off the alarm. If getting abruptly woken by a loud alarm makes you want to slap that snooze button, you guessed it — this one’s for you! The clock also has dual alarms, so you can set different ones for you and a partner, weekdays and weekends, or even just as a backup. Beyond these features, it’s really just a basic, inexpensive digital clock. It doesn’t have a radio or any other special features. It simply wakes you up and tells the time and that’s it — and to most of the 4,000-plus Amazon reviewers who’ve awarded it an overall rating of 4.3 stars on the site, it’s enough.

The alarm clock comes in black with a red or green display, or in brushed silver with a green display.

Enthusiastic Amazon review: “I bought this alarm clock because I didn't like the really loud alarms - I don't need a really loud alarm to wake up, and if the alarm is too loud I may turn it off before really waking up. This one starts with single beeps that get progressively louder and closer together, but I'm usually up by the second beep. It gives me a better start to my day than the louder ones I've had. I also like that it has two alarms so I can have a workday and weekend alarm saved. It's also nice that the display is red - this makes it less intrusive in a dark room.”

While this programmable coffee maker from Cuisinart isn’t technically an alarm clock, you can set the device to brew coffee at a specific time up to 24 hours in advance, and it beeps so loudly when the coffee is finished that multiple Amazon reviewers suggest the sound (and the smell of freshly brewing coffee) is enough to wake them up. So if a lack of coffee is the only thing getting between you and starting your day, this coffee maker is a creative solution that could really make a difference. And since it doesn’t have a snooze button, there’s really no option but to get out of bed and pour yourself a cup.

When you don’t need the noise to serve as an alarm, you can disable the beeping that informs you when the coffee is done brewing, as reviewers report it truly is very loud. As for the quality of the coffee, well, most reviewers seem pretty pleased with it, giving both the 12- and 14-cup versions an overall rating of 4.5 stars, from among more than 28,000 reviews.

Choose from a bunch of different finishes, like stainless steel, black stainless steel, and matte black. The 12-cup version has a thermal carafe that keeps the coffee hot for hours, which could be handy if some coffee drinkers in your household get up earlier than others. The 14-cup version has a glass carafe.

Enthusiastic Amazon review: “I know, it's just a coffee pot but easily became my best friend, I am 74 and it seems with the same brand coffee and the same brand filter in a different pot it is different coffee. I have known this for decades and so it is hit and miss to buy a pot... I put the coffee in at night with the water and just press "ON" in the morning and the coffee is done in about six minutes and stays perfectly hot for two hours and shuts itself off. I can then press the button again and get another two hours of great coffee. I don't have anything bad to say, You can set the timer and the coffee will be ready when you get up ( I am retired and get up when I want so I don't use this feature) [and] change the temperature and brewing time.”

Whether you’re a heavy sleeper who needs a quiet alarm that won’t wake your partner or you’re just looking for an alarm clock that’s possible to ignore, this Pavlok alarm is truly a versatile solution. While it doesn’t actually tell time, the alarm clock takes its “alarm” function seriously. It can wake you up by beeping or (for a silent option) vibrating, and if that doesn’t work you can set it to give you a little electric shock to really encourage you to get out of bed. You have the option to adjust the strength of the zap (it has 100 different levels ranging from 50 to 450 volts), and you can set it to zap you if you attempt to snooze or turn off the alarm. The idea is that the shock gives you a nice, wakeful dose of adrenaline — or trains your body to wake up in order to avoid getting shocked in the first place. Of course, the zap is totally optional if you don’t want to shock yourself. The alarm can also be set so the only way to turn it off is to do jumping jacks, or to scan a QR code in another room, to help promote wakefulness.

The alarm can also be set to wake you up when you’re in a lighter stage of sleep, making the whole experience less jarring. You control the Pavlok via a smartphone app, which also has options for using the device to break bad habits, encourage good ones, and even track sleep.

Enthusiastic Amazon review: “I have delayed sleep phase syndrome and when I do go to sleep and am a very, very, very heavy sleeper. I'm a 44-year-old adult and I've been sleeping through multiple alarms since I was a teenager. It's difficult because it's one of those problems that unless you have it yourself, people just don't understand it. It can be hard to have a professional career and set 15 alarms and still sleep through an alarm clock. Function as a normal adult? I'm trying...been trying. In a bit of desperation, I found this and bought it for myself for Christmas. All I have to say is I'm so glad I did. The shock set to maximum wakes me up, and I'm out of bed doing jump and jacks immediately.”

If you like the idea of waking up gradually to simulated sunlight but don’t want to drop the big bucks on the Philips SmartSleep, this super popular JALL sunrise alarm clock may not be clinically proven but has many of the same features. And with a 4.6-star overall rating on Amazon from more than 13,000 reviews, it’s safe to say it’s tried and true.

The alarm clock can be set to brighten gradually over the course of 10, 20, or 30 minutes, with a soft yellow glow that mimics sunlight. This can be accompanied by your choice of seven sounds, which include natural noises like birdsong and waves, or more typical alarm noises like beeping or music. You can set two alarms if you want a backup or you have a partner who needs to wake at a different time. As far as the snooze function goes, you can press the 9-minute snooze button up to five times. This makes it a bit of a gamble for chronic snoozers, but if you find the slow increase in light wakes you super effectively, you may not even wish to snooze at all.

In addition to the yellow sunlight glow, the device can glow seven other colors, and can be used as a reading lamp thanks to its adjustable brightness. It also has an FM radio. Choose from a white or wood design.

Enthusiastic Amazon review: “This alarm clock is one of the most innovative alarm clocks I have ever seen. Every since I purchases it a few weeks ago, my night and morning routine have improved dramatically. I no longer need my iPhone for an alarm in my room at night which improves my sleep and relaxation. The light feature works perfectly as my reading light and the fun colors that I can choose add a fun ambiance to my room at night. The alarm settings in the morning are reliable and fun. I wake up each morning to a soothing piano riff and a simulation of the sun rising, 20 minutes before my alarm goes off.”

For those who require their alarm clock to jolt them awake by making a noise that’s comparable in volume to a thunderclap or chainsaw at close range, this compact timer from Screaming Meanie is a must-have for home or travel that makes it hard to fall back asleep. The device is really intended for one thing — getting your attention, loudly, at your desired time — but Amazon reviewers say the bare bones gadget does this job well. Follow the instructions attached to the back of the device to choose between your Screaming Meanie’s two volume settings, 70 and 120 decibels (120 is the thunderclap-level noise, while 70 is more like the volume of a vacuum cleaner), and set it to go off when you need to wake up. This is a countdown timer rather than an alarm clock, so that’s something to keep in mind if you require a clock, but tons of Amazon reviewers report that it’s super useful as a morning wakeup alarm. If you like to snooze, there is an option to snooze the Screaming Meanie — but according to reviewers it’s only twice and only for 5 minutes at a time, so it really does keep snoozing to a minimum.

The lightweight timer is approximately the size of a smartphone, making it easy to tuck in your bag or pocket for travel, and runs off of a 9-volt battery you’ll have to buy separately. The plastic case is designed to be ultra-durable, ideal if you think you might fling it across the room in the morning. It comes in black, yellow, or green, but you can’t choose the color you get.

Enthusiastic Amazon review: “I was very skeptical after reading the reviews but decided to give it a shot. I have narcolepsy so I have so much trouble with my sleep/wake cycle. My husband is also a very heavy sleeper. We were constantly late for work and desperate to find something. We have used this alarm/timer for the past month and haven’t been late once. It is so loud. We both use our cell phone alarms plus an alarm clock on the other side of the room and was still oversleeping. We set this alarm/timer and put it on our dresser and as soon as it goes off we are bailing out of the bed. Absolutely love it!”

There are plenty of good reasons as to why the La Crosse might be the best alarm clock for you. For one, it does more than just tell the time and wake you up. It also projects the time to your ceiling, meaning that you can get a good idea of the time without having to fully open your eyes all the way after briefly waking up in the early morning. With its 360° projection image rotation, you’ll be able to project with ease.

But, that’s not all. It’ll also tell you what the indoor temperature and humidity are, so you can help prepare for your day. It also includes a calendar, so you’ll never forget if it’s Tuesday or Thursday.

Enthusiastic Amazon review: "Works great. The projection is red so [it] doesn't [keep] you awake. It is also the only projection that I found that could be rotated completely around so no matter where you put the clock, the time could always be adjusted. ALSO has a zoom or focus dial to make it more clear. The display light on the clock can also be adjusted for brightness.”
