We bought this oven to replace the oven that needed to be replaced.  We went back and forth from cheaper ones to this one.  Best choice we made.  Started to boil frozen hot dogs in water in less that 2 minutes.  Its definitely heats up faster than the old cook top.  Once you learn the temps, your golden.  Use a few eggs.  Use different temp.  You'll see what cook faster at certain numbers.  You waste a few eggs and learn a lot.
