Rated 1 out of 5 by from Save yourself from the agrivation I wish that I had went to this site and seen the reviews for this microwave before buying at a local store. The reviews on the door latch breaking are so true. After only owning it for a few months the door latch stopped working right. We had to slam the door to get it to latch then that even didn't work. My husband was able to look at it and fix it by bending the metal piece back in place and using some wire to secure it all . Well that part is still working but however now the top plastic door latch has broke off. The microwave will not start up now. I used to think panasonic was a great brand. I will not be getting another panasonic microwave.

Rated 1 out of 5 by from Bad Door Latch When closing the door, you have to push very hard, and the "boom" is very loud. Even after that, you are still not sure if the door is closed properly or not. Very often either the light does go off, of the microwave does not start to work, or both. A lot of microwave sold for lower price work better than this one.

Rated 2 out of 5 by from Door Latch Broken Had this for a couple for a couple of years and in the last few days the door latch doesn't work properly. You have to push the top and bottom of door together for light to go off. Now the timer has broken - when it gets to zero in the count down it resets itself and starts the cooking time over again!!! Have always thought Panasonic a good brand but will NOT be buying another. Not worth repairing. Wish I'd read all these reviews about the door latch

Rated 4 out of 5 by from Perfect Popcorn! :) I just bought this microwave after my children killed my old one. I love that this one has actual buttons, not just a flat surface. I decided to test this one with the one food that most microwaves have the most difficulty with: popcorn. This one had no trouble AT ALL! I next tried frozen macaroni and cheese; typically one has to keep a close watch to avoid the 'burned on the outside, frozen on the inside' fiasco. Not the case with this model. I am very impressed and happy with my purchase.
