Had this for just over a year. We didn't have much of a choice as we purchased a new home and the builder used GE products.  Despite regular cleaning of the screens we continuously had problems with the grease not getting vented...and we don't even deep fry.  Sautéing vegetables, pan frying salmon, etc is about as greasy as we get.  The surrounding cabinets have grease all over them.  When we finally realized this wasn't normal and looked into solving the problem (possible vent issues, fan installed incorrectly, etc) we learned nothing is wrong, it is just a poor product.  Now I need to buy another range and spend several hundred dollars on an appliance that is just over  year old.
