I bought this 6 weeks ago and the temp of the oven is all over the place. Pre heat signal goes off before it is even preheated. So what good is that function if you can't rely on it. I set the temp to 350 and it goes up to 375 then drops down again. The temp isn't consistent. I haven't baked anything right in this oven so far. I called the appliance store that we bought it from and was told we couldn't get a repairman to me for 2-3 weeks. This Christmas time!!. I need an oven that I can rely on. Yes I am disappointed in this product.
