I need to wake up at 5AM everyday and sometimes I don't hear my alarm ringing no matter how loud I put it and it's right next to my ear. I'm sure there are some kind of alarms which you can strap to your foot or arm and they will begin vibrating or I don't know.. something of that sort. I looked on amazon and most vibrating alarms don't have reviews so I don't know which one to buy. It doesn't have to vibrate but it has to wake my up. And it needs to be more then a BEEP. Any recommendations will be greatly appreciated.
