Summary: First of all, I love Panasonic products. This was to replace a 9 year old model that worked fine until I snapped the latch off with a bulky sweatshirt. There are two parts to this review. How it was shipped and the product itself. Purchased this from Amazon directly and with Prime shipping. The product supplier link has changed twice in 3 weeks and is no longer from Amazon.
Summary: This gizmo requires a branched 120vac circuit because it pulls 14amps while running, Most household circuits running around the walls are 15amp plugins total & usually have 3-5 plugins, Without a branched circuit & plugging this thing in to the existing 15a circuit only leaves 1amp to run everything else that's plugged in if the gizmo is running, Bottom Line: circuit brkr pops.
Summary: This is the third Panasonic microwave that we've owned. All three the same model and they have all lasted about the same amount of time, about two years. The inverter is the part that goes on them and It's almost as much money for the part as to replace the whole unit. In defense of Panasonic it appears that the inverter technology is common to the microwave industry and all brands seem to have the same problem.
Changes from last model have improved this product some

Summary: I wrote a review on the model that preceded this one. See way below. Improvements: 1) This item is heavier, so there is no longer an issue with sliding. 2) Along with heavier came larger, taller and roomier. Love it for that! 2) The button that opens the microwave requires a great deal less pressure to open. 3) It doesn't require as much pressure to close. 4) The knob is quite useful to me. It is much easier than punching buttons (Panasonic buttons are a bit stiff).
Summary: Nice, seemingly well built Microwave oven. The Inverter technology allows good modulation of the power instead of just cycling full power on and off. Very roomy cavity with lots of headroom. Very attractive & easy to clean. The sensor modes work about as well as can be expected, as they simply monitor steam emitted from the food in order to determine that a food is cooked. The encoder dial (instead of a numeric keypad) is no real advantage.
