Spec of this microwave looked good so I bought it. It is cheaply made with very thin stainless steel sheeting making up the shell. Also, the unit I purchased did not sit firmly on its four rubber feet just like a wobbly chair or table. So now it has a Heath Robinson wedge under one corner. Not very satisfactory in terms of design and construction. However, functionality is sound and it works well but does get hotter than other microwaves I've used. I have other Panasonic products which are very well put together but it seems that their microwaves are not in the same class.
