You do not have to purchase a new high end fridge to get the pleasure of listening to an audible alarm if you left the fridge door ajar. The Fridge Alert has a light sensor that activates if the door is not closed. It gives you 30 seconds before you receive the warning which is loud enough to be heard in the next room. It even has a thermometer at the front to let you know how cold your fridge has stayed thanks to this annoying let gadget.
