I bought this about a month ago.  I used it for a lot of cookie baking initially.  I found the timing needed for my cookie recipes was a bit different than my former oven.  The racks fit so tightly in the oven that they are actually scraping the sides of the oven when moving them.  The other issue is you most definitely need to keep the oven locked when not in use because it has been accidentally turned on several times, once causing a plate that was sitting on the stovetop to break.
