Fridggi

FRIDGGI will help you close your fridge or freezer door when left open or ajar and avoid wasting food. Kids frequently leave the refrigerator door open, making the unit's compressor run hotter, which means it takes longer to cool and burns more electricity.

Unlike regular chimes or alarms, FRIDGGI only emits a single beep when the door is opened, then a progressive Di Di alerts after 1, 2, and 3 minutes; you have 59 seconds to take food out of the freezer or refrigerator.
