AYRELY® Super Loud Twin Bell Alarm Clock for Heavy Sleepers Adults, 4-Inch Retro Silent Non-Ticking with Night-Light, 3D Raised Number Dial, Battery Operated for Bedroom Bedside (3D Dial – Red)

I used to have an old fashioned wind up alarm clock with a hammer and bells. That thing was LOUD. Scared the shit out of me every time it went off. I eventually gave it to someone who slept through everything and it worked very well for him. Get one of those and put it on the other side of the room and you'll never snooze again. This one looks similar, but has batteries so you don't have to remember to wind it up: https://www.amazon.com/AYRELY%C2%AE-Sleepers-Non-Ticking-Night-Light-Operated/dp/B0FVPHYSQV/ref=mp_s_a_1_2_sspa
