Burton Egg Perfect Egg Timer, available at Amazon, $8.92
The annoyance: No matter how much you try, you can never get the timing right to make the perfect hard or soft boiled egg.
The solution: A heat-sensitive timer that tells you exactly when your eggs are ready. Place the timer in the pot of boiling water along with your eggs. As they cook, the timer will change color, signaling to you that the eggs are ready. There are three settings — hard, medium, and soft — so you can choose exactly when to take out your eggs, and know they're cooked to your liking.
