I purchased this item for a friend that is phyically challenged and can’t reach the timers usually found on the oven or microwave. She was able to set the timer and wear it around her neck so she could hear the timer go off wherever she was in her house; she was so delighted with it, she even sent me a poem about her “Lil Yellow Timer that goes Ringy Dingy”! I would recommend this type of timer for anyone that tends to lose track of time and either can’t see or hear a regular timer when it goes off.
