Dont Hesitate a Bit- Buy It Now!!

If you know a heavy sleeper or are one yourself, you absolutely HAVE TO buy this alarm clock! My husband would set 12 different alarms every morning for work, all varying of different sounds, volumes, aome with lights, etc. We have been together for a very long time and after 20 years of trying to buy him different alarm clocks and also waking up every morning in a full blown panic because it sounded like a parade going off IN my bedroom..I wyite literally googled "What is the loudest alarm clock on the market that you can buy" ..this one came up first and I decided to give it a try.. fully thinking "oh im sure my morning panic parades will continue ". well, they didnt. AND HE ACTUALLY WAKES UP TO IT ON HIS OWN! Now granted, It is veryy loud so I still wake up myself because since having kids I am a light sleeper anyway..But this difference is- its ONE SINGLE alarm noise, with a vibration on my side of the bed from the bed shaker he keeps under his pillow. When I tell you that a bomb couldve went off and this man wouldnt have wolen up before but noww he does with thiss Sonic bomb clock- I am not even exaggerating in the slightest bit! Matter-of-fact, we had 5 gnshots go off outside in front of our house, which essentially is directly outside our bedroom window -I woke up immediately and got everyone including our dogs to safety behind something (just in case)..he slept through most of it even with me yelling out his name to get up and get away from the windows! Another time the SWAT team came for the house across the street, and there were so many different loud sounds, Including them yelling through a megaphone and shooting those things through the houses windows, gn ahots, drones, robots on the ground entering the house after they busted the door down- it was something out of a movie I swear- He stillll slept through it! Until I felt safe enough to go by the window and shake him awake is the only way he woke up that night into morning! when I tell you to biy this thing for your heavy sleepers - Run, dont walk. Don't even hesitate for a second.Just buy it- trust me on this %26 thank me later! Be forewarned though: If anybody is sleeping in that same bed or even the same room as that alarm, they too will in fact wake up! Amazing Alarm clock with the flashing reds lights and the bed vibration shaker.. I don't see how anyyyyone could not wake up to this alarm, impossible! So yes, I very highly, highlyyyy recommend you buy it!! Best Christmas Gift I've ever got him!!

this alarm will wake you.

this alarm definitely wakes me up. i was a little nervous about the part that shakes the bed because i put it under my pillow, but its fine. It doesn't hurt. The alarm is plenty loud; i didnt turn it up all the way so it can get louder. this will definitely help me get up on ti.e for work.

I never recommend unless asked. This is the 4th clock I've tried and the only one that I could hear without aides. When my hearing gets worse the pillow vibration attachment will hopefully do the trick. We are retired and seldom need an alarm, but when I do I prefer not to have my husband wake me. Lots of buttons on this clock, unnecessarily complicated. Blessings, JoAnn S.
