Quality convinced !!! Before I decided for this egg cooker, I also read a lot of reviews, which I agree to a large extent only, the shape is perfect, the eggs are cooked measuring cup 100% as specified by the water. Of course, small deviations are possible, but each egg is different in size and even a drop of water more or less. The mark on the water measuring cup is very well developed as already described by others, unfortunately, clearly not kept in color, but a black Edding has since quickly remedied. Now the signal that the eggs are done, sure there are quieter tone detector, but you should the signal was indeed take and I have already had several egg cooker that still much more unpleasant were the sound so that this sound is still within the tolerable. For indicator light, then it would not be wrong if the egg cooker they would have, but not absolutely necessary. When the cooking process is completed, the device answers as already written not audible, is it the unit then returns to the cabinet or away, no more cable in the wall outlet should be and when you remove one pays anyway it if the egg cooker, a or switched one is there this even now wants to use. So my judgment is generally, this is the best we have ever egg cooker. We are very satisfied and can only recommend this egg cooker !!!!
