Super Loud Alarm Clock with Bed Shaker for Heavy Sleeper, Dual Vibrating Alarm Clock with USB Charger for Hearing-impaired Deaf, 7.5’’ Large Display with Dimmer, Snooze, 12/24H & Battery Backup

I have had this alarm clock for almost five years, now, and it still works great. I live with roommates and the vibrater is a great way to quietly wake me up on time. It isn't silent, but it is quiet. There is also volume control for the alarm sound, and display brightness control, which I use every day(turn it up in the morning and down at night). The snooze button snooze for exactly 9 minutes, and even though that's a bit random, it's kind of nice, as someone who struggles to get up the first time. It's a really a nice alarm clock- not to much, but is holding up really well for almost five years of use!

This alarm clock works so well for heavy sleepers like me. The alarm clock is smaller than I expected and the packaging was very secure. Figuring out how to set the clock was so easy because it came with easy to read instructions with pictures included. The sound and volume of the alarm is so loud that it wakes me up right away. My phone alarm can't wake me up if you want and idea of how loud it is. This alarm clock comes the with 2 alarm's that you can add just in case you want a backup alarm. I do recommend this product for anyone who has a problem waking up on time.

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

I bought this for my husband once we had a newborn sleeping in our room, and I didn’t want his loud alarm waking our baby in her bassinet . We use the vibrating only function under his pillow. He is a heavy sleeper and this works to get him up, so it’s great. The only thing I would say is that it also wakes me up because the vibration alone is loud enough and you’ll feel it through the mattress as the cosleeper. So just a word of caution there. Otherwise the clock is simple to use, love the different levels of brightness you can adjust the clock to you, and it’s effective at what it does for heavy sleepers.

son has hearing loss. He heard THIS. The bed shaker was too much. He jumped up and threw the clock! So Yeah It works. I recommend. Make sure u install battery so when victim unplugs it, it will still work.
