  1. This bed shaker always wake me up! Shaka waka! Review by KitKat
    Overall Satisfaction

    The shaker can be so creepy if set right and get you out of the bed like the earthquake is coming. I've been using this product since 2015, and I've developed a fear of the alarm that I wake up before the alarm goes off. It's not bad but it gets the job done! LOL

    So about 2 years later (now) I somewhat noticed my minute button isn't working too well due to the constant time setting change for the alarm but it hardly works much when I need to fix the time to be 2 minutes head or so, while setting the alarm time still works. Along with this, I also want to request the alarm clock to have more than 1 alarm set so the button won't be abused.

    Other than that, this thing rocks the bed! (Posted on 8/25/2017)

  7. actually wakes up teenager Review by hunter
    Overall Satisfaction

    Product is wonderful. It actually wakes my teenager up which surprised me. I do get amused when it the alarm goes off as it sounds as though it vibrates the house. I'm amazed that the alarm clock wakes him up as I've set off the smoke detector outside his room and he didn't wake up which scares me. (Posted on 8/10/2015)
