Egg Minder
3 of 10
The eggminder is a tray that measures whether your eggs are still fresh. It also notifies you via text when they're about to run out.
But who would really buy a device with a list price of $50 to track the freshness of $3 eggs?
Plus, there's a free method to check how fresh an egg is -- the float test. If the egg sinks in a bowl of water, it is safe to consume. If it floats on the surface, you should toss it out.
