Reusable heat indicator that helps you cook eggs to the exact doneness you want. Place it in the pot with your eggs while boiling; the device changes color to indicate cooking progress so you get consistent results every time. Clear doneness feedback: the indicator shifts color from red toward green to show soft, medium, and hardboiled stages. Use the color change to remove eggs at the exact level you prefer, avoiding undercooking or overcooking. Durable, foodsafe material: made from foodgrade plastic that is safe to use with food and designed for repeated use. The construction resists breakage during normal kitchen use. Easy to clean and maintain: handwashable for quick cleanup after use. Compact design makes it simple to store and take with you. Simple to use: no settings or timers required — drop it into the pot with your eggs and monitor the color change as the water heats. Practical use scenarios Home breakfasts: consistently prepare soft or hardboiled eggs for family meals without guessing cook times. Meal prep and recipes: get reliable results for sliced eggs on salads, sandwiches, or ramen where exact doneness matters. Travel and outdoor cooking: compact and portable for use while camping, at a cabin, or in any kitchen where you boil eggs.
