Who hasn't gone to rummage through their refrigerator only to find the door already open, and for who knows how long? Leaving the fridge door open too long can let out all of the cold air, which can spoil your food and add to your energy bill.
But not if you have a refrigerator alarm. This helpful device will alert you if you leave your refrigerator door open for too long by mistake. Most alarms even allow you to set the specific amount of time that passes before the alarm sounds. So if you like to take your time browsing the contents of your fridge, no problem. You can still do so in peace without worrying about the constant beeping of the alarm. You can just set it to alert you if the door stays open for a longer amount of time.
