Product review (1 stars): Do NOT buy without a warranty!!!
Unfortunately myself and the other reviewer bought this at the same time, so I did not see her review until it was too late.  I purchased it in April 2013, and started using in July 2013 when kitchen remodel completed.  Immediately there was a loud buzzing when using either the top or lower oven.  Repairman came and fixed that.  A few weeks later, the lower oven would not reach the temperature it was set to.  Repairman came and replaced board.  A few weeks after that, neither oven would reach temperature; repairman came and again replaced board (was great that this was happening in the middle of the holidays!!!!).  Now this a.m., I baked using the upper oven at 350F, then reset to 325F for another recipe.  Upper oven temp had gone down to 290F at the time of the reset, and never made it back to 325F.  I turned the upper oven off for about an hour; when attempting 350F again, it seemed to work this time.  So now we are going to contact the "high end" appliance store and let them know how poor this oven works, as well as Kitchen Aid.  I am very dismayed with this product; we have a Kitchen Aid dishwasher that is pretty awesome and I was really not expecting this!

The last repairman out here mentioned that "all" of the newer ovens have this problem with the circuit boards getting overheated and fried; he said I should plan on getting another oven in 5 years; and whatever I do, do NOT use the self-cleaning feature!

So glad we bought a 5 YEAR warranty.  :(
