The green indicator light lets you know that your waffle maker has been preheated. Simply pour the batter, close the lid, and move the knob to adjust the temperature. Closer to the MAX, the crisper and more golden the waffle will be. When the green indicator lights up again, you know that the delicious waffles have finished baking. The waffles have extra-deep pockets for your favorite ingredients. Due to its non-stick cooking surface, this waffle maker is also easy to clean. Although it makes two waffles at a time, it reheats and cooks quickly, so you can easily make one waffle after another.
