Loved mine for its convenience and look, it feels very futuristic to just press the button and not having to set the time. Had it for few weeks and mostly been heating up leftovers and coffee/tea, defrosting works great too. Preset functions for cooking pasta and popcorn feel a bit gimmicky, and I haven't tried them. Microwave gets a bit moist after, so I have to wipe it off and keep slightly open to properly dry, but it's minor downside. Keeping mine and recommend it to anyone.

This review is for the Panasonic Japanese Microwave NN-SF57RM, 1.0 cu. ft., 1200W I ordered this because I just can't pass up a new innovation. I always like being quick to try something I've never used before, and this microwave really intrigued me. I already had a nice microwave, but it was so super small that I constantly had trouble fitting taller dishes inside. This one looked like it would still have a modest footprint on the counter while giving me more usable interior space because of the flatbed design. The feature I was most interested in was the Genius Sensor cooking. The idea of not having to guess how long to reheat something sounded wonderful. How many times have we all reheated leftovers, checked them, stirred them, put them back in, and repeated the process two or three times? I was hoping this would eliminate a lot of that. I purposely waited a while before writing this review so I could actually learn how most of the features work. What I've found is that I use the automatic sensor settings much more than I expected. My favorite is the beverage sensor. I used to microwave coffee and tea by time, but I've learned that different mugs, different amounts of liquid, and whether the drink starts out refrigerated or room temperature all make a difference so that the time is never predictable. With the beverage sensor, you simply choose one of five temperature levels. I personally like the second level because it gets my coffee hot without burning my lips. My husband, on the other hand, still prefers using the timer. That's perfectly fine too, but I notice he's still checking it and adding more time, while the sensor gets it right the first time for me. The reheating sensor for plates of food works the same way. You choose how warm you want the food, from lightly warmed to piping hot. I usually use the middle setting, and it's been working very well for leftovers. I still stir things up halfway through. There's a really cool progress bar that gives you a visual clue to where the halfway point is. The microwave also has popcorn, auto defrost, and other one touch cooking options, although I haven't had a chance to try all of those yet. One thing I wasn't expecting to enjoy so much is the pull down door. Instead of swinging out to the side, it opens downward like a wall oven. That means we were able to place the microwave right against a wall without needing clearance for a swinging door, which actually saved us counter space. I also like being able to set a plate or mug on the open door for a moment while I'm stirring or checking the food. It's a surprisingly practical design. The flatbed interior is another feature I appreciate. Without a turntable taking up space, taller and oddly shaped dishes fit much more comfortably, and it's soooooooo much easier to wipe clean. The only thing I've found myself wishing for is a dedicated butter softening button. I'm sure there's an easy way to do it manually, but it would have been a nice convenience. I'm really enjoying this microwave. The sensor cooking has turned out to be much more useful than I expected, and the pull down door and flatbed interior have both made everyday use more convenient than my old microwave.

Just when you think there is nothing new in microwaves, this one comes along and changes everything. It may not look a lot different, but the first thing you might notice is that the aspect is a bit different. I have been using a previous model of Panasonic inverter microwave for some years now. I have been very pleased with the higher power and how well it has worked. This new Panasonic model improves on that performance by changing the whole way it works. Gone is the turntable that on some models never seems to stay where it needs to be. There is a nice clear deck that's non slip so plates aren't going anywhere. It's not likely, as they never move during cooking. Instead, the larger lower area has the microwave assembly and that rotates to give the food overall coverage of cooking power so it's applied evenly. Add the active sensors and it monitors progress until it's done to completion. This technology applies to reheating a plate of food or your cup of coffee as there are specific settings for many various types of cooking requirements. It can all come down to a one touch solution in many cases. You aren't going to be trying to get a plate in around a side opening door, as the pull down door operation allows easy operation from any position. It's also a soft close with a very quiet catch mechanism which is a very welcome improvement. It does operate a little differently and a good read of the well written instruction manual is recommended. Keep it handy as you will probably need to refer to it for a while at least. Since this microwave requires less figuring of times and power settings in many cases, you will get used to how simple it actually is to operate. One feature I appreciate is Defrost, as I usually have some frozen fruit at breakfast and have seen how this microwave actually does a better job than my other one, automatically. I've also used it to cook a potato, which is a regular selection for me. After piercing several times as I usually have done, I spray the surface with The size being slightly taller but not as wide as most other microwaves allowed placement in a corner of the kitchen where a wider one would not fit. One thing you will notice is that the fan continues to operate for a little while after cooking to cool the microwave components which presumably provides better performance with longer service life. While this microwave offers a lot of automation in the sensor technology, it can also be operated in manual mode with the Microwave button - starting at full power with each press it goes down ten percent and then the dial controls the cooking time. There are probably a lot of new things I will find as I use this microwave more in the future, and there's a cookbook provided by Panasonic which has a lot of interesting recipes. Most people probably use a microwave to cook prepared foods, and these days it's become evident that processed foods may not be the best. This microwave offers a way to cook fresh food selections from scratch and be able to cook them properly but quickly. I look forward to trying some of these recipes and some things that I have made in the past with different methods. Even that popcorn button.

I wish I could give this oven 10 stars. I'm a microwave snob—for years I didn't own one (I like to cook the old fashioned way), and then when I had kids and needed to reheat things often, I got one BUT I hid it in the pantry. Microwaves have never been the object of great design—until now. Within days of receiving this, I had gotten rid of my Panasonic pantry microwave (yes, I'm a die hard Panasonic fan. Shout out the the FlashXpress toaster) and installed this very prominently in my kitchen. It opens like an actual oven—what a concept—which makes so much sense when you think about it. All other microwaves on the market (at least that I've seen, and I've seen a lot) have the hinge on the left side. If you need to store it with its right side to the wall, you'll be annoyed that it opens the "wrong" way. I also love that you don't have to press a huge button, just pull down on the large handle and it opens easily. A close second in terms of innovative features is the turntable-less design. I was skeptical about this but hopeful, as turntables are not only a pain in the ass, but they limit the amount of usable space to what can fit on them, leaving the corners unusable. With this, you could fit a large pyrex lasagna in it! And the best part is: it works. My food gets reheated evenly. Perfect. Now let's talk about the smart sensor. My previous Panasonic microwave had this feature too, version 1.0. To be honest, I didn't use it very often because it would often cause my food to splatter, so I took to using a plastic plate cover and manual settings. (The smart sensor doesn't work if your food is covered.) This baby comes with smart sensor 2.0 and it's really neat. I love that you can choose from 6 levels of heat. You put your food in, press the knob button, and then dial to your preferred level. Personally, I only use the lower 3-4 levels. The top ones will get your food/drink boiling (and yes, splattering). Did I mention the looks? This is the best looking microwave I've ever seen (except for uber-minimalist Muji or IKEA ones, but they are low end, simple machines). It looks like something from the future and yet it's reassuringly familiar as an oven. I love this microwave. It's expensive, yes. But is it worth it? Yes. Leave it to the Japanese to lead us into the future.

The chief innovation with this microwave oven is the removal of the turntable. Apparently, there is still a hidden turntable underneath. But it no longer rotates the food. Instead, it rotates the rays that are being emitted to cook the food. As my mom used to say, “It’s a new world!” Removing the turntable makes for a more modern and stylish look, for sure, but it also makes the interior of the unit much easier to clean. And, without actually making the microwave bigger, this flatbed feature greatly increases the useable capacity of the oven; you’re able to get much larger bakeware and food items in there. The other innovation is the use of Panasonic’s patented inverter technology to more evenly heat food and optimize the cooking process. How that works sounds like some serious Elroy Jetson mumbo jumbo to me and I don’t pretend to understand it all. But it does seem to work. I get an even cook on anything I put in there, from baked potatoes to lasagna to frozen pizza. And there are no unheated “cold” spots. Be aware that this unit features an unusual drop-down door. (In other words, rather than opening from the side, the door’s hinge is on the bottom, like a toaster oven.) I wasn’t sure I would like this and it does take some getting used to, but it’s neither here nor there. I don’t see any great advantage to it, but I don’t consider it a drawback, either. It’s just… different. The overall look is clean and compact and modern. I personally would have preferred a natural “silver” stainless steel finish instead of the cold grey that this comes in, but, hey, maybe that’s just me. (They describe it as “metallic grey,” but because of the dark glass door, the overall effect is black, so I’ve taken to calling this the “microwave of death.” I like it very much, but let’s face it: it’s a lot closer to the Death Star in appearance than the Starship Enterprise. This, too, will take some getting used to.) The unit is relatively quiet when it’s running and has an outstanding, but optional, “no beep” feature. If you choose, you can silence the audible beeps that occur in response to your button touches. I haven’t seen that feature before, but, then again, I haven’t updated my microwave oven in seven or eight years. For all I know, this is now a standard feature on all new microwaves. I like it and opted in... no beeps for me! This option is easy to select as part of the initial set up process, which should take no longer than a minute or two. The other customizable settings are a bit more complicated, but there are also several “one button touch” options, as well. This microwave oven has rapidly become an essential kitchen tool in my home, perfect for cooking, reheating and defrosting. It’s easy to use, with intuitive buttons and settings and… this was a shocker… a clock that actually seems to keep good time. With every microwave I’ve ever owned, the clock was always seemingly an afterthought. The clock would lose about a minute a week and would have to be constantly reset. The clock on this microwave appears to keep accurate time. And while there are a lot of other compelling reasons to get this unit, the fact that the clock works properly is a minor miracle and a cause for celebration!

Having owned and operated microwaves ever since they were first introduced back in my youth, I can confidently say I have seen the technology evolve over the decades. Yet, the Panasonic Japanese Microwave (Model NN-SF57RM) is a completely different beast than any microwave I have ever used in my life. It has officially redefined what a kitchen appliance can do, setting a massive new baseline for modern cooking. The most shocking change you will notice immediately is the complete absence of a traditional turning tray. For years, we’ve been told that a spinning glass plate is mandatory to ensure even cooking—but this model doesn't have one because it simply doesn't need it. Panasonic has engineered this unit with highly advanced dynamic sensor technology that actively scans the interior to detect hot and cold spots in real time. It then intelligently and automatically redirects the microwaves specifically to the precise areas that require the heat. This sensor-driven engineering is revolutionary in and of itself, but the real-world benefits in the kitchen are game-changing: Maximum Usable Footprint: Because there is no rotating carousel restricted to a central circle, the absolute entirety of the flat cooking surface is completely usable. You can utilize every single square inch from corner to corner. Simultaneous Mixed Cooking: You can place a variety of completely different food items into the microwave at the exact same time—things that would normally cook at wildly different rates—and rest comfortable knowing they will all finish cooking perfectly at the exact same time. The sensors balance the energy distribution flawlessly. Deceptive Interior Space: Do not let the spec sheet fool you. Despite having a relatively compact 1 cubic foot oven footprint on paper, the flatbed design means it actually has significantly more usable cooking space than traditional turntable microwaves twice or even three times its physical size. You can fit large, rectangular casserole dishes that would normally jam a spinning tray. The design departures don't stop with the interior. The door opens differently than almost any other countertop unit on the market, dropping downward like a traditional full-sized kitchen oven rather than swinging out to the side. This makes loading and unloading heavy dishes incredibly stable and ergonomic. One crucial piece of advice for anyone purchasing this model: it comes with a comprehensive user manual, and this is definitely not a booklet I would suggest ignoring or tossing in a drawer. You absolutely need to take a few minutes to educate yourself on the unique features and programming functions of this machine. Because it operates so differently from standard, old-school radiation boxes, it can cook a vast array of complex foods that you are likely not used to preparing in a microwave. Panasonic has truly engineered a masterpiece here. If you are ready to move past the 1980s turntable design and experience true, intelligent culinary technology, this model is worth every single penny. It is brilliant!

This is a panasonic microwave, which is a top brand. It has the inverter technology which helps to sense when food has heated. This particular miocrowave has a pull down door, which in an online search is called a Japanese style?? Anyway, this microwave is taller and more narrow than my other Panasonic Microwaves, which gives me more counter space. BUT, the pull down door gives me less prep counterspace directly in front of the microwave. The instructions say to prep inside the cavity of the microwave. Hmmm. Not sure that is convenient. The outside buttons and dial are simple. A big problem with the latest Panasonic microwaves that I have seen is that the labeling on the front is in small no-contrast lettering. Sleek, but illegible without a direct flashlight shining on on the labels, other than the start dial and timer. ugh. Also, the inside light, while happily in a Panasonic brand non-toxic environment, is grey, and the lighting does not light the entire cavity. I have seen this lighting problem on the newer Panasonics. But, the heating of the food is great. This particular microwave has a fan noise that continues after cooking. Not too loud, but not my preference. But you can program to turn off the beep when you press buttons. There is also a child lock, if you need that. There is no turntable as in other microwaves. But you do not need this as this technology is carried out in another way. Thus, you have more room inside the microwave to put your food and rectangular continers, and it is now easier to clean. The programing buttons are all on the bottom of the fold down door, so you have to shut the door in order to program your foods. It is an attractive, sleek microwave. I like the one buttonn inverter so I don't have to figure out how much to heat something. If you put cardboard browner around a burrito, this feature will not work because the cardboard is in the way, fyi.

For almost $430, whether this microwave is a good value or not depends on your budget; however, it is an excellent microwave with technology more complex than I understand which works amazingly well. This microwave doesn't have a regular plate that spins; there aren't any visibly moving parts to it, aside from the door you can open. Despite that, it heats even better than most any microwave that does, because it has a 'hidden turntable' (which actually means the antenna under the surface rotates, not the food), sensors, and an inverter that helps make sure food gets heated evenly throughout the whole volume. The door swings open on the front like a toaster oven, which is surprising at first, but is highly preferable, it's easy to use the whole microwave without needing to clear out a wide swath of counterspace around it. It has tons of features, which I can't even try to list all of, but all of them rely on a mix of temperature and humidity sensors. You don't have to use them, and you can just input your time and strength setting, but all of the ones I've had food to try them on work very well. It's fully possible to just put your food in a microwave-safe bowl, put it in the microwave, select how hot you want it to be, and hit go; the temperature sensors do a good job of making sure the food reaches about the same temperature based on the setting you pick. I really appreciate the setting that lets you turn off the beep noise, that's great if you appreciate the quiet. Speaking of which, the microwave itself is pretty quiet when running, it only really sounds like a small fan is on, at most. The fact that there's no turntable also makes it easy to clean, you can just wipe off the inside of the microwave whenever needed. As for downsides... It's very expensive; if you're looking for a dorm room microwave, this almost certainly won't do it for you unless your budget is very high. * I only review things that I personally use myself and keep using often. * I always give my full, honest, unbiased and unfiltered opinion on everything I review. * I will not hold back or avoid describing any issues I have with a product. * I write exactly what I think about things - the good, the bad, and everything in between. * If I get multiple of something it's because I regularly use and need both of them. * And, I update my review if something breaks, stops working as intended, or otherwise doesn't hold up as expected.
