I bought this product in May 09 having been directed to it in my search on your website for new seals for this model of oven. Those being replaced had rounded corners so I had to cut the new seals with mitred corners to make them rectangular. My wife finds that neither the top nor bottom doors close very tightly with the new seals fitted, resulting in the oven exterior getting very hot around the door edges and also the cooking times have been affected with unpredictable results.
