  1. Not Bad but....... Review by Emado
    Overall Satisfaction

    Not bad. Good product function. But..... I did not like the cheap plastic of the buttons. They get easily damaged. (Posted on 2/28/2018)

  2. Awesome Review by Soozie
    Overall Satisfaction

    I purchased this for my Dad who is deaf. He would wake up all night to check the time, fearing he would oversleep, but now he sleeps through the night waking at 5 am. to start his day. Thank you for this awesome product. (Posted on 1/22/2018)

  3. 4+ stars Review by phil
    Overall Satisfaction

    worked as advertised. Had a rather short life, as believe a very severe electrical storm somehow terminated its life. Tried to call service number to get their opinion, no response. sent in Email request no response. since it rings loud, I simply replaced the same model with the one I purchased from Harris. Thanks for quick service. (Posted on 11/30/2017)

    Easy to use. Powerful shaker. Very effective! (Posted on 9/14/2017)

  7. Just as advertised! Review by Jack
    Overall Satisfaction

    Clear instructions. More program steps that I like, but works as advertised.
    A "backward time" feature would make programming easier. IF you miss a desired time during fast scroll, you must scroll thru 24 hours to reset the time.
    Very effective alarm for those of us who have serious hearing loss. (Posted on 9/11/2017)

  10. Shaker will wake Review by Earthquake
    Overall Satisfaction

    I am profoundly deaf so the buzzer on the bomb does not wake me, but the shaker is extraordinarily powerful and never fails to wake me. Impossible to sleep through! Great product. (Posted on 7/6/2017)

  11. bed shaker not the bomb Review by Almost 5 stars
    Overall Satisfaction

    I expected a more powerful bed shaker because of the name Sonic Bomb. A stronger bed shaker would get 5 stars. But it does deserve a 4.5 star rating. 4.5 isn't an option so I'm stuck giving a 4 star rating. (Posted on 3/31/2017)

  12. GREAT! Review by Jeff

    The clock is the best I have had for many years. It provides many cool features that the previous ones did not have.

  14. Great Clock! Review by Ann
    Overall Satisfaction

    I know longer fear my boss calling and waking me up because of this alarm clock! It's loud enough to wake me and the vibrator alone would wake me up.
    The only criticism of the clock I have is you can only set the clock and alarm ahead and not back. (Posted on 10/3/2016)
