I have had two convection ovens. The first one was electric and the current one is gas. I use the convection setting for nearly everything I bake or roast, and have never had a problem with a hot spot anywhere in either one. I typically have upwards of 20 people at my house for Thanksgiving dinner. Baking a minimum of 4 pies, and sometimes as many as 6, that oven with its 3 racks is a godsend. And it also does a great job on the turkey, with nice crispy skin. I've not found any problems with Christmas cookies, either. It sounds to me like the problems noted may be with certain makes and models, and not with others. Either that or it's hit-or-miss from one oven to the next.
