DreamSky Vibrating Alarm Clock for Heavy Sleepers - Auto Set Bed Shaker Alarm Clock Under Pillow for Hearing Impaired, Bedroom, Travel, Rechargeable Battery Operated, Cordless, Auto DST, LCD Backlight

My wife is a heavy sleeper and this vibrating alarm clock has been a game-changer. She used to rely on her phone alarm, but would sometimes turn it off completely by accident instead of snoozing it. She keeps this clock under her pillow and has woken up every single time it goes off. The vibration is strong, and it’s easy to adjust the intensity or switch time zones when traveling. She charged it once when she first got it and hasn’t had to recharge it in the couple of months she's been using it. Highly recommend for anyone who struggles to wake up with sound alone.

This is the second alarm clock like this that I’ve purchased. (I moved and haven’t found the first one yet) I love being able to put this alarm clock under or beside my pillow where I can hear the alarm as soon as is goes off plus it’s convenient for traveling.

Works great as a person who doesn’t sleep near there phone and can’t wake up to any alarm. Only bad thing about this time is that when it gets to a low battery it will lower the volume so you can’t feel the vibration as well so then I’ll end up sleeping it. Keep it charged and it will do just as you like!

A very good alarm clock. It is just what I needed to wake me up without waking my wife. I put it under my pillow and its vibration quietly wakes me every time. It is very easy to use. After 7 months of use, the spring on the cover broke, making the door unable to close automatically. I contacted DreamSky. Even though it was out of Amazon's return period, since the spring could not be replaced, they sent me a new alarm at no charge. I recommend this DreamSky alarm clock to anyone who needs a reliable alarm clock that can wake you, without waking others in the room. It's good to buy a product that is backed by its vendor.

I needed an alarm to wake me up when I’m away from home and didn’t want to carry those big plug ones especially when going out of country the outlet isn’t the same so looked for something I used to have called “shake awake” alarm found this and it worked well.

Love this little alarm clock. I recently switched from a smart watch to a regular watch and my phone alarm wakes my husband up. This I can set to just vibrate and place under my pillow. I had it at 100% the first time and it was so intense that my husband jumped upright in a panic haha 40% vibration intensity does it for me to wake me up. I also love that it charges with a usb type c cord vs needing batteries. That makes it easier to travel with. Overall, I’d recommend this product and am very happy with my purchase.

Pros:This alarm certainly gets the job done: I keep it under my [memory foam] pillow, and the vibration at 65% absolutely, definitely, irrevocably wakes me all the way up in an instant. Also, the battery life has been surprisingly good: I haven't had to charge it since I got it, five months ago. I was not expecting that kind of longevity.Cons:As at least one other reviewer has noted, it's really hard to find the off button without tapping the snooze button first. I don't want to snooze! So I end up opening the lid to switch it all the way off, and that increases the risk that I'll forget to turn it back on before the next night's sleep. And it's difficult to open that lid by feel; I always end up turning the thing over and over in my hands a couple of times before I get ahold of the very subtly raised edge. It's also quite slippery, and I'm always afraid it's going to slide out from under my pillow and fall under the bed while I'm sleeping.Overall, I feel like it works very well for waking me up, but the user interface is terrible.

Works better than any other clock i found at waking me up. Would highly recommend if your a heavy sleeper
