Since using this new Kenmore Elite I'm very disappointed in the panel. My last oven had a much more friendly program for quick heating items with an 30 second add on. Also, it had l,2,3, up to six instand buttons for quick cooking. Just hit the number and it would start the machine and cook for that length of time. This machine isn't user friendly at all. I haven't had an issue with the tray like most others have written about, guess I'm fortunate on that issue. I wouldn't purchase this again. As for the cooking, heat things mostly, good for popcorn but again its special button doesn't...
