Summary: I purchased mine 3yrs. ago. I chose Panasonic because of the inverter technology. It does a great job warming and cooking at half power. There is not the popping and spitting you still get with a non-inverter microwave running at a 50% duty cycle. My problem, like many others, was the door.
Summary: The door latch design is ridiculous. After 12 months, the door refuses to open. There's something with the latch system that prevents the it from releasing to open. You have to wrestle with the push mechanism to get it open. Equally as bad, it doesn't fully close.
Summary: I bought the microwave back in the Summer of 2013. For the most part the microwave cooks food really well. Plenty of power and options. But this Fall, we started having a problem with it. When we close the door to cook food, the microwave still thinks the door is open.
Summary: Originally, I simply adored this microwave. I have had it for three years now, and it is no longer serviceable in any way. The sad part is, I don't even use the microwave that much...just reheating occasional leftovers or making hot water. So what happened?
Summary: This is a well designed unit electrically and it's control system is excellent. After two years, the metal bracket which holds the door latch became distorted and the door was having trouble closing properly.
