Hi Dawn, well mine is about 5-7 years old, so that may also have a bearing. Gosh, I wish I had two full size electric ovens, and a huge countertop range, in gas, of course, well I can dream, haha! You know, one of those 6 burner and grill etc, haha. Right now the counter top is two burner with grill that you can change to use as 4 burner and it is electric.
But I can tell you this, of all of the ovens that I have ever had, this is the first one that actually bakes things in the exact recommended times, so it must be dead on, as far as the temperature goes. And it really is so much easier on the old back, having it up and in the wall. And cleaning it, well that is a breeze, I am so impressed with that feature as I really don't like cleaning the oven.
Don't know how expensive they are where you are, but here they are super expensive.
