Two of the 3 sheets were supplied with a little extra, namely traces of rust, it vobei possibly "only" dealing with rust, especially reassuring that still is not, however, the third sheet has bubbles / rough spots in the coating, let's see how long they holds (the coating).
The second criticism relates to the frame, it has a not inconsiderable gap back to, so we occupied the pizzas with vegetables that loses during the baking process fluid, etc., so that may well lead to a beautiful mess (and not just for Christmas) if the liquid runs over the edge and branding on the oven floor.
The frame is delivered disassembled, the connections are but solved plenty of unsatisfactory, the side panels each have a hook on the top and bottom of the rear frame member has a fix soldered eye and where the hooks of the side part has to be pushed in the side, but this is the eyelet aufzubiegen, and after the hook has found its place again bend back so that the frame is not immediately broken down by itself. But I hold before doubts whether a repeated open / Zubiegen and not sooner or later lead after each use at a fraction of the solder joints, so I'll keep the frame well in together laws state because it takes but then quite a lot of space and can not simply disappear with the sheets in one load.
