RoxicoslyVibrating Alarm Clock for Heavy Sleepers, Super Powerful Adjustable Vibration, Travel Bed Shaker Clock for Deaf Hearing Impaired, Battery Operated, USB-C Rechargeable, Cordless, Dual Alarms

Works better than expected, especially for the price.I have it under my pillow, and even on the lowest setting, the vibration is more than enough to wake me up. That is pretty impressive as I've slept through hurricanes before.The instructions were easy to interpret, and the settings are not complicated. Also, the battery life has been longer than advertised. I was worried about it running out of power quickly and needing to redo all the settings, but so far, that has not been an issue.The display is clearly laid out and easy to understand, with the time displayed large enough to see without putting my glasses on. Not that that is a concern when it is under my pillow, but a nice extra. Definitely recommend for deep sleepers.

Great little clock, small, quiet and runs well.

When adjusting the alarm times, either wait until the alarm settings change back to the normal time or else you will have to go through the full setup including choosing the volume level each time. This can be annoying if you are trying to adjust the alarm at night while others are trying to sleep. Otherwise works great.

This alarm clock is a total game-changer for me. As someone who struggles with waking up in the morning, this little device has helped me get up immediately every morning I have used it. Combined with my new Amazon Echo Spot, I am now able to get the day started quickly and efficiently with the shaker function. It is simple to set up and use with the provided instructions and has an impressive battery life. The company's customer service team have also been very helpful and responsive, which I really appreciate. I consider it to be an excellent value for the money, and it has a bright display with easy-to-use buttons at the top and on the back. I can't recommend this alarm clock enough for anyone else who has trouble getting out of bed early in the morning. See my pictures for reference.

I really enjoy the design and features of this clock. The buttons are really easy to use and the clock is very user friendly. I like the vibration level settings so I can set it to a level that won’t wake my spouse up. I also like the options of setting multiple alarms based on the day of the week.

It worked amazingly well for this heavy sleeper, but less than a year later, it quit alarming. It's fully charged, it shows the time and shows there's an alarm, but at the time of the alarm going off, it dies. Super frustrating!

So I’m a super hard sleeper and this alarm along with the vibrating bedside alarm are the ONLY thing that wakes me. I recently purchased this handheld one to keep under my pillow. I got to use it a few times until I went to set the alarm button 1 and 2 and they both got stuck down. So with them broken I can’t set the alarm. I didn’t apply to much pressure just lightly pressed it as I normally did when I set it but they just got stuck and won’t come out. I’m asking to send this one back and to please have it replaced. I’ve only had it a couple weeks and sucks I can’t use it now. I’ll change my review to 5 star if you can please replace the broken one.

This functional alarm clock is the best invention ever. It’s sleek design and great sound are just what I needed to make my mornings more efficient. Great customer service too! I’ve been using their products for over a year now.
