After having break hundreds of alarm clocks, she bought a rooster who could wake her up at dawn, and since it was a living animal, it'd be able to evade the pillows, shoes and punches she'd usually throw at her alarm clocks to turn them off, and the best part was that if any or all of those things ever hit the rooster instead of turning itself off, he would cry louder for the pain it would feel and would definitely wake her.
The end.
