The sound is not that loud but the shaker OMG crazy how good it is. It wake me up every time

This clock works very well. I bought it for my son who would wake up to his regular alarm clock at all and would sleep through the sound of the alarm ringing (I tried a couple of different ones with varying sounds, none worked). He would end up getting up late for everything. He can't do that with this clock. The bed shaker has him up and going the moment it goes off and he hasn't woken up late since we started using it. If you are or know someone who is a very heavy sleeper, this is the clock to get.

This alarm clock does exactly what it promises. It’s very loud, and the bed shaker is incredibly effective. The display is clear and easy to read, and setup was simple. It’s perfect if you struggle to wake up or need something dependable for early mornings. Definitely one of the best alarm clocks I’ve owned.

Everything worked as intended like the speaker, and the time settings. I was even able to slow charge my phone overnight with it. The only problem I had with it was that the vibrating puck kept slipping out from underneath my pillow and falling to the side of my bed. I wish there was a built in way of anchoring the puck to the bed or a pillow. I worked around this by slipping it into my pillowcase with a fashioned device to keep it in place.

My 10-year old vibrating alarm clock stopped working. I shopped around and bought this one. I seldom write reviews. But I am so satisfied that I'd like to share my experience with everybody. I hope that the manufacturer reads reviews, as I'll mention one thing that I hope they can take into consideration when they design their next model in the future. Pros: 1. This alarm clock uses two AAA batteries as back-up during power outage. AAA batteries are cheaper and less bulky tnan 9V battries that my old alarm clock used to use. 2. The display is bigger and brighter than my old alarm clock's display. 3. I really like the DST function. It works like this: You first set the clock time to your local Standard Time. Then in March when DST begins, you push the DST button. It adds one hour ("springs forward") to the clock time. In November when DST ends, you push the DST button again. It subtracts one hour ("falls back"). There is a small indicator on the screen to tell you if it is in DST mode. I wish that the DST function can be automated. But I imagine that it'll make the cost higher. At this price point, I am happy enough with this simple button. 4. It has two alarm buttons ("Alarm 1" and "Alarm 2") so that you can set two different alarm times. I only need one to wake me up in the morning. But some people may find the second alarm time useful. 5. The vibrator works as advertised. It shakes me out of my bed. I don't use the ringer. So, I can't comment on that. Cons: 1. There are two buttons, "Alarm Pause" and "Alarm Off". When the alarm goes off in the morning, you press "Alarm Pause" to stop the alarm for the day. It will go off again tomorrow morning. If you press "Alarm Off", it turns off the alarm completely. That is, the alarm won't go off until you turn it back on by pressing some other button. So far, so good. Here is the problem: These two buttons are right next to each other. So, in the morning, the alarm goes off, you get out of the bed, still kinda sleepy, you want to press the "Alarm Pause" button to stop the alarm. But if your finger slips and presses the "Alarm Off" button by mistake, then you'll wake up the next morning 2 hours late, wondering why the alarm didn't go off. My suggestion to the manufacturer: When you design your next model, consider relocating the "Alarm Off" button to an entirely different place. I'd suggest move it to the right side, next to the "Ring/Vib" button. I still give this product 5 stars, because I consider this shortcoming quite minor. I'll simply make the habit of checking the "Alarm On" indicator on the display every night before I go to sleep.
