I also had the sonic one. I used the vibrate. It shook my whole bed. Only problem is the display is too bright, so you need to put it face down. Also, it is junk. But, it lasted a while.
My Sonic vibrating one could be dimmed.
Mine also. Even the dimmest was way too bright. I just wanted to throw it out the window. Or turn it face down.
I use an electrical Smoke Alarm (hard to find) which can wake a dead person.Hold the test button in with a piece of scotch tape Attach it to a digital timer and yo';re good to go.You can probably attache today's battery operated Smoke Alarms with to a low voltage adapter/transformer.
