After the previous Panasonic microwaves interior became unhygienic (due to blistering of paint and rust, it was over 20 years old though) I didn't hesitate to get another Panasonic. What a disappointing product this new one is. For some reason, it seems like the Panasonic door is sealed and if cooking vegetables, the interior is saturated with water. Every surface is wet to the point water drips everywhere. I have to now wipe firstly with a dishcloth and then dry with a tea towel after every use. It very high maintenance. The interior is starting to mark and the cynic in me would say its designed this way, so you need to buy a new one (Which means more electrical items into landfill). I will get a new one sooner rather than later but it won't be another Panasonic.
