Rated 3.8 out of 5 by 12 reviewers.
Rated 5 out of 5 by Pleasantly surprised with appearance, ease of use, inside space and the quietness of the product when functioning. Great product. July 2, 2015
Rated 5 out of 5 by Replacement This is my second purchase of an NN-989. After 4 years, the first one I owned, had a major malfunction. Initially tried replacing the original, however, there were none available anywhere in the USA, so I ended up purchasing another brand which was not as user friendly. As soon as the NN-989 became available again I made the purchase. Great oven! Ease of use is the key reason why I to have this Convection Microwave oven and no other. May 18, 2015
Rated 5 out of 5 by Love it!!! Have only had my microwave/convection oven for a month, so far so good. My favorite features are the Sensor Reheat, Popcorn & Quick minute. The bagged popcorn comes out perfect, 3.5 for the larger bag. I also like the inverter defrost, sometimes you have to guess at the weight but it does a very good job of defrosting quickly without cooking. My last Panasonic micro/conv, oven lasted 29 years, before it gave up the ghost. This is a replacement for that one, 29 year later upgrade from my original. If this one lasts half as long as the other one, I will be pleased. Will reserve more judgment for later. April 7, 2015
Rated 4 out of 5 by good micorwave this is a nice puchase. a little more than i expected to pau but it gets the job done. family loves it March 23, 2015
Rated 5 out of 5 by Pleasantly surprised This is a successor model to our previous Panasonic convection microwave. Changes in technology since we purchased the original unit had us concerned about our ability to use it effectively, but we decided to stay with Panasonic and quickly discovered it was a wise choice. It is well constructed, works very well, reliable time, temperature and ancillary data, automatic functions are perfect and the unit is easier to use than our previous one. July 30, 2014
Rated 5 out of 5 by Not only is it a microwave, but its also an oven! This microwave / convection oven is very easy to use. For most of the features, all it takes is three easy steps. 1. Push the function (microwave, broil, bake, sensor reheat, combination, defrost, etc.). 2. Turn the knob for temperature or time / weight. 3. Push start The most convenient feature is their one-touch sensor cooking and reheat. I’ve reheated multiple items and found it to be fairly accurate. This feature was able to consistently reheat items to an acceptably warm but not hot temperature. Only thing a bit strange is that the fan stays on for a bit after the microwave is done. However, that’s only a minor nit. For the microwave, broil, bake features, it works just as well as any microwave and convection oven. Very simple to use. What really stands out is the combination feature. This feature does indeed speed up the baking process without overly drying out the food. Only bad thing on this feature is that you can only select 4 predetermined oven temperatures (275F, 300F, 325F, and 375F). For most of the items I want to bake, the temperatures are close enough. However, just beware of these preset temperatures...and it doesn't specify the temperatures on the oven...only in the user manual. Also, its tough to guess how much shorter to reduce the oven time. I been reducing the cook time by 1/3 and seem to overcook items a bit. A few other features that I rarely use but have found that they perform well: defrost and keep warm functions. I’ve defrosted a few items and found that the items become less frozen but are not completely thawed out yet - just enough. In addition, I’ve found the keep warm function an interesting feature. It seems to microwave the items for a long period of time (at a low setting?) to keep the food warm. Overall, the microwave / convection oven seems sturdy and well bit with nice stainless steel surface and solid buttons. I haven’t had this long enough to attest to the durability over the long term. Besides a few shortcomings I’ve mentioned, this unit seems to work as advertised. I would recommend this device to anyone that is looking for a dual microwave / oven (or want a microware and a second oven). Just be aware that this unit is a pretty large and will take up quite a bit of counter space - make sure you measure out the space before ordering. February 6, 2014
Rated 4 out of 5 by Great easy to use microwave This microwave makes things easier and faster in the kitchen. It's super easy to use. It's sleek elegant appearance matches my appliances in the kitchen. I really like that it's a convection oven and microwave in one. I broil my food now and my pizza and pies taste delicious as it would be done in the oven except now it's easier and faster. Heats up and defrosts my food in to time especially when I am in a rush. My favorite option is the keep warm option which let's me keep my food warm until the moment I serve it. The menu option is also pretty useful, gives me instructions on how to cook what I need.

Rated 5 out of 5 by Great Convection/Microwave Read the instructions or use the onscreen display directions (that can be turned off)....broils nicely and perfectly. Convection bakes great~Combination cooking is perfection. I had another brand (expensive, well known one) that only lasted 4 years and this Panasonic is much better quality. It even cleans up better after use than my old one. The unit does build up a lot of heat on top, so my cabinet above does get hot, but it did with our old unit, too. The door does not get so hot you can't touch it like another review said though. All in all this is a great design and works as stated by Panasonic. September 7, 2013
