I personaly dont know so much about electronic things.but my sister is obsessed with the sandwiches she loved to eat sandwiches so for that my papa buyed a sandwchich maker from amazon and seriously she in loved with this toaster because it gives perfect crispiness in sandwich in just few minutes.and the most important think it takes very few minutes to cook.when the sandwich maker is being heated up you just have to put your sandwich in toaster.all you have to do is to see the green light and take it off when it shows red light or switched it off .and you will get a perfect sandwich.would recommend you.:)
