As a person who hears from only one side, I can tell you that it's easy to oversleep when you have your good ear on the pillow.No more regardless of how I end up in the morning (good ear down or up), the vibrating disc has not failed me yet. I hear and feel it every time.I would suggest, however, to put it under your fitted sheet located just below your pillow. With my tossing and turning at night, it has fallen down the first few nights. After I placed it under my fitted sheet, that issue was solved. Plenty of wire remains to do this and still have your alarm clock in the perfect position on your nightstand.Highly recommended for those of us with hearing issues.

Finally an alarm clock that I don't just keep hitting snooze on. The attached shaker doesn't scare or severely startle you, but it definitely works. I respond much better then my phone. I actually sit up and get out of bed.

I hv not had to wake my son since purchasing this clock. THIS DOES THE JOB TO THE MAX! GET IT IF U HV OR IS A STUBBORN DEEP SLEEPER.

I'm a pretty heavy sleeper sometimes and this alarm clock always wakes me up with it loud beeping alarm. I don't use the bed shaker option, but the alarm itself is always enough to bring me out of a dead sleep. It could just be me but it seems like if I don't turn it off right away that it continues to get louder as time goes by, but as I said it might just be me. The display is big and bright enough I can easily roll over and see what time it is even without my glasses. It's definitely worth a try for someone who has trouble waking up especially in the morning.

It's too bright, I wish it could be dimmed.In addition to the buzz of the shaker and the piercing beep of the alarm, my bird also finds it pretty startling, so I get 3 loud noises waking me up at the same time.However, a huge drawback is that it doesn't work with just batteries in it. The batteries only make it remember what your alarms are and what the time is if it gets unplugged. For it to be operational, it needs constant power from the wall, which is annoying, because I constantly am needing to switch what is plugged in due to the plug by by bed only supporting 2 things being plugged in at once.I actually don't even use it anymore and went back to using my phone as my alarm for this reason.

The brightest and being able to hear the alarm.

Setting the time and alarms is too complicated. And if it comes unplugged I gotta start all over.

Phone alarm clock is extremely louder than the alarm clock. I thought ordering an extra loud alarm clock wouldn't even compare to my phone ...but no!!! Again the phone is louder. Will not buy again. Sorry

The alarm is not Loud as advertised. Its thin, awkward, and falls over easily.

I really don't have anything negative to say about this product. Overall its pretty sweet!Its cracks me up every morning to wake up to the bed shaking.If you don't want that feature on its simple to turn off. It reminds me of back in the day and putting quarters in the vibrating beds In the motel room. I think if you had 4 alarm clocks round your bed This thing would be just like one of those vibrating beds.Overall great product I would definitely recommend this to anyone that can't hear the alarm going off. Just place the vibrating device under your pillow or something in that general area

better than was expected,nice and loud . bed shaker is awesome.

I'm probably the deepest sleeper in the world. I usually have three alarms that do not work if I'm tired but this thing is a lifesaver. That vibrator thing is the key. It's that extra movement that helps us deep sleepers wake up.

Nothing wakes me up. My phone's blasting alarm is hit-or-miss which is risky when I have morning classes. I live in a dorm with very thick walls and doors. You cannot hear anyone speaking on the other side of the wall. One time I forgot to turn it off and, with all the doors closed (my room and main door before going to the hallway) and around 3 corners, you could hear this in the HALLWAY. I love it has 2 alarms so I can set them 10 minutes apart for when I need to get up and for when I REALLY need to so I don't miss class. I wake up to both, I just might consciously ignore the first one and wait for the second to actually get up and run out the door. You can change the brightness of the clock so it is really dim or practically a night light with 5 settings. The vibration part is helpful too for that extra morning wake-up boost but you can also choose to have just the loud alarm or the vibration or both. Easy to change clock and alarm times. It has little icons on the side of the front display to show you which alarms are turned on. Snooze button is large and right in the middle on the top, so it's hard to miss. There are little nub things that you can put at the bottom of the back so it doesn't fall over. I have a roommate under my room (suite-style dorm) and it wakes them up (oops). I'm up fast enough to turn it off quickly because of the alarm.I wish I could adjust snooze times, but having 2 alarms set makes up for that.I have done hours of research for the best alarm clock that will wake me up and this is the winner. My brother also has one and he legit sleeps through police coming and going through the house and I think only wakes up to fire alarms other than this clock.10/10 recommend for heavy sleepers.

Like the way to change brightness and the long cords for both the plug and the motion piece

It's just loud enough and the vibration is a little extra help to make my daughter wake up, finally!

its loud!

It's working so well for him. He finally realized that he needed something louder as he hasn't been hearing his alarm clock. This is the answer!

The buttons on the alarm clock either get stuck or stop working for a moment. It's hard to turn off the alarm when it goes off. I have to press the button about 4-5 times

This Alarm is the best thing for heavy sleepers! Very good that it has the option to not use the bed shaker if you don't want to. I would buy again for sure!
