Review on Wake Up With Ease: ANJANK Extra Loud Dual Alarm Clock With Bed Shaker And USB Charger Port For Heavy Sleepers And Hearing-Impaired by Sara Mahoney

So this alarm can wake up an entire home full of people. I purchased this for my teenage daughter who can sleep through an explosion. Initially it was great we only used the vibration feature and it made her fly out of bed. Then eventually she wasn’t getting up on time and said her alarm didn’t go off, I checked and it was fine. So we added vibration and noise. And again it was amazing, she would fly out of bed. Then eventually same thing, she was waking up late. I found out this alarm shuts off on its own offer 1 minute, and also I found her getting up to turn off her alarm and going back to sleep without ever remembering.So if you are a person who doesn’t sleep through tornados coming through your home, this would work fine. Unfortunately for my kid this (along with sleep stubbornness) doesn’t always work.
