The ones we've seen look rather cheaply made. We're pretty sure our relatively new (~6 mo. old) oven is not heating properly.
Recipes that turned out fine when baked in our previous oven need lots of extra time and still often get done on the outside but are soupy/raw on the inside.
We received some new cookbooks as gifts recently and want to try them out but hate to waste ingredients or have negative first impressions because of the oven.
