The sound this alarm clock makes is like an Atari video game, light flashes, and vibrating disk freaks out! It was a pretty bad-ass way to start the day. Then if broke. The disk goes off every time I set it. Just not a well made product.I am sending it back to the manufacturer because it has been more than six months and amazon won't let me return. Sonic boom say they can repair or replace it...but I have to pay for this shipping to Missouri! x'pWish I listened to the bad reviews they where so true!
