This Panasonic Genius Prestige Microwave is smaller than the other unit but the reviews are just as positive. Great Cooking Performance, Sturdy Construction and Clever Design Choices (like the dial controls) made this a real well-reviewed appliance. Customers were very satisfied with this model to point of calling it "perfect". A great choice for a mid-size model.

Pros: Great Cooking Performance, Sturdy Construction and Clever Design Choices

Wheres's the recall?

By  from Abbotsford, BC, Canada
Overall Rating: ☆☆☆☆☆ ★★★★★ 1

Obviously after reading other reviews there is a problem with the door latch/sensors. I have an expense piece of kitchen art instead of a working appliance. How has Panasonic not recalled these?

Like apparently every other consumer who trusted the Panasonic brand, I have a broken door latch and a non functioning microwave after a few short years. Hoping Panasonic will offer to remedy its design shortcomings. No one budgets for having to replace a basic core kitchen appliance which has had light use every 4 years....

Poorly Designed... on my second one

By  from Texas
Overall Rating: ☆☆☆☆☆ ★★★★★ 2

Unfortunately I need to replace my existing Panasonic built-in with another, or I wouldn't have bought my second unit. My other microwave "broke" because the door locking mechanism attaches to a rather flexible piece of sheet metal that isn't supported. With continued usage, the metal flexes and the door mechanism stops working. Constant readjustment further weakens the metal. All Panasonic had to do was provide a small piece of support, or even an extra bend in the metal. Instead, I get to buy a new Panasonic Microwave every few years to overcome their quality design problems. I like the features and functionality. I just don't like having to replace an appliance due to design problems.

Great while in operation, very poor durability

By  from Vancouver, BC
Overall Rating: ☆☆☆☆☆ ★★★★★ 1

This is the third Panasonic microwave oven we've owned over the past four years. The first failed very quickly with a broken door latch mechanism. It was replaced by our local appliance dealer under warranty. The second failed almost a month to the day after the warranty expired. Reason: broken door latch mechanism. Our dealer provided us this new Inverter equipped Panasonic. It lasted the longest - approximately 2 years - until, you guessed it, the door latch mechanism broke. We have quite a few Panasonic products in our home including a 55" Plasma TV. We will no longer purchase Panasonic microwave ovens until they eliminate the frail push-button door latch mechanism.

Door Switch Failure

By  from Auburn, CA
Overall Rating: ☆☆☆☆☆ ★★★★★ 2

Bought in 2012 and in December of 2014 it's failing as manu others I've read. Have to slam the door to MAYBE get it to work. Bad design. I'm now looking at a Breville model for replacement.

Inverter Impressed

By  from Reston Viginia
Overall Rating: ☆☆☆☆☆ ★★★★★ 5

Recommended Product:

I recently bought the inverter technology for my home and I only wonder what took me so long to make the change. I like the cook bacon wrapped in paper towels to make them crispy and remove a lot of the fat. The problem has always been that the outer bacon often got burned while the inner was not yet crispy. Not so with the inverter. The bacon is as crispy in the middle as in the outer portion and it is all crispy without being burnt and taking a lot less time to cook. Popcorn and prepared foods are also in perfect balance. The only negative is it took me so long to make the change. Great device at a great price with the best cooking results I have ever experienced in a micro wave.

Bitten by the Door Latch Issue

By  from Oregon
Overall Rating: ☆☆☆☆☆ ★★★★★ 2

Sadly, our NN-SD797S Panasonic microwave is dead-by-door switch. We've had it less than 2 years now and clearly many here have the same issue with this model. Normally I'd make a change but we did the built in kit and it was more expensive than the microwave itself. :( Now the hard choice... buy another and know it's a throw away or bite the bullet and go to a different brand/model and have to do the built in kit for it. No good choices it seems.

Door latch is of poor quality and design

By  from Montclair, NJ
Overall Rating: ☆☆☆☆☆ ★★★★★ 1

We bought a Panasonic NN-SD797S microwave back in October 2011 and it has completely stopped working after moderate use. From the beginning the door had required a hard push to close which was quite annoying. However, now the door mechanism has completely failed( July 2013.) My wife called couple of local appliance repair shops, and they all said don't bother repairing this unit. I searched the Internet, and just as other reviewers have noticed, door latch problem appears on multiple Panasonic models. When I opened the microwave to see what the issue was, it simply appears to be bad design and poor quality parts. I certainly would not recommend this product to anyone, and will be quite reluctant to buy/recommend any Panasonic products in future.
