also if the waffle iron isn't preheated enough (there should be a little indicator light on it to let you know it's hot enough) the waffles will stick or burn ont he outside but not be done in the middle (BTDT) ALSO It helps to leave the top open for about 30-45 seconds before putting the lid down. I don't know why. But mine always turn out better when I let the bottom get hotter than the top.
