This review is for the NN-SN67KS. I was on the fence based on some of the reviews, but had to see for myself whether or not such a highly rated microwave was worth the trade-offs, price premium, and risk of failures. Was the inverter technology so life changing that I could put up with some of the negative points others brought up? Were the concerns even real? Here’s what I found.2.4GHz wifi interference: I was a bit skeptical, thinking there must have been something unique about the situations of reviewers that reported loss of wi-fi signal while this microwave was operating. Well, sure enough, while the microwave was running, here are some things I noticed. 1) my wireless IP security camera lost signal; 2) the video streaming to my google Chromecast got pixelated then paused and buffered; and 3) our wireless baby monitor (not network connected) lost signal. To be clear, these devices mentioned were all wirelessly connected via 2.4GHz. All devices that were connected via 5GHz (phone, iPad, etc.) were not affected at all. I can see this not being an issue at all If you only use fairly new devices and phones.Clock button: A couple users complained of having to set/re-enter the time every time they accidentally pressed the ‘clock’ button. Apparently, it was too easy to accidental hit the ‘clock’ button since it was right next to the ‘0’. This is a non-issue. If you accidentally hit the ‘clock’ button, you don’t have to re-enter the time. Just press ‘stop/reset’ button. This will cancel it and the time will show up again.Beep: It’s all perspective, but in my opinion, this had the least obtrusive and lowest volume “done cooking” beeps of all the microwaves I've ever heard. 5 short beeps. (long beeps always sound like they’re yelling at me). Note that opening the door will not stop the beeping. If you really wanted to, you can turn off all beeping sounds coming from this microwave, but you can only access this option when you first plug it in (or you can unplug and re-plug it in). Without pressing any other buttons first, press the ‘start’ button twice to access the option. Then the ‘timer’ button will allow you to cycle between on and off. Pg 11 of the manual covers this. Note that this will turn off all beeps including button presses.Light: In my opinion, it is on the dim side. The light itself is decently bright, but the problem is that it doesn’t cast a wide beam and there are defined shadowed sections where the light doesn’t hit. And while the dark grey interior gives it a modern look, it doesn’t reflect light like the more common white interiors, which makes matters worse. Not a deal breaker alone, but something that I had to get used to.Keypad buttons: - I found that this unit require noticeably harder keypad button presses. Coming from a unit with a more responsive keypad, it was a slight annoyance to have to pay attention to whether the keypress registered and whether I needed to shift my finger slightly or press harder.Other thoughts:- Of all the microwaves I’ve owned, this required the lightest touch to close the door. It follows that it also had the quietest latching sound. Overall, the mechanical build quality is top notch.- No one button start. Even the ‘Quick 30s’ button requires you to press the ‘start’ button. This was a big negative for me having come from a microwave that had one button start for 30sec as well as 1-6 minute cook times. But I knew this going in and thought it might be a small price to pay to have the inverter experience.- No flat plug. I used a 1ft flat plug “extension” cord since I needed it to sit against the wall with an outlet behind it. I posted a pic of the space behind the microwave. There are plastic standoffs that space the microwave a bit from the wall, but there’s zero chance the included straight plug will fit.- Another thing I noticed is that porcelain dinner plates and plastic splatter covers got much hotter (with the same temperature food) than with my previous microwave. I suspect this is related to the inverter technology. The thermal images in their marketing product pictures also seem to show a higher temperature mug, so probably not just my imagination.After 3 weeks of wanting to love it, ultimately, I ended up returning the unit. The little compromises just added up to be too much to put up with. After having to give up one button start, the additional trade offs of 1) the wifi interference, 2) keypad effort and 3) needing oven mitts to remove hot plates (a little exaggeration, but I certainly considered it on many occasions) was just a little too much. Who knows, maybe if I heated more frozen foods that tend to have cold spots (rather than just reheating refrigerated leftovers), perhaps the inverter technology would have been more life changing. Or maybe I'm missing the fact that it's all about the sensor cooking (which I didn't use) instead of the inverter technology. For whatever reason, people seem to love this microwave (Panasonics are also highest rated by Consumer Reports). But for me, it was just ok. In the end, this unit just made me realize what a major convenience it was to have one button start (specifically 1-6 minute). Anyway, good luck with your decision. I hope this review was helpful.
