I bought this oven a few months ago and everything I cook in it burns.  I have tried lowering the temperature and the time but if I'm not paying attention to it the item burns.  I know that the temperature is right because I have used a thermometer in it.  I had an older model the this oven and used it for about 10 years before it wore out.  I got this one to replaced it but I'm very disappointed in it.
