    Great Microwave. We love this microwave. It’s sleek and user friendly. It has the features that we were used to and at a great price. The inside light is a wonderful feature and quiet beeps that aren’t as bothersome as others. I didn’t think that I would like the front but it’s beautiful.

    Good at Reheat/Defrost, want “time defrost” option. The microwave does a good job of reheating, defrosting, etc. My only complaint is that from what I can tell it doesn’t allow you to select a time defrost and forces you to defrost based on weight and then doesn’t tell you how long the defrost will take once the weight is entered. With my old microwave I knew how long it took to defrost certain things like baked goods, etc. and I preferred the time method over by weight especially because often I’m guessing how much something weighs and it varies by item whether the weight is an accurate way to defrost.

    Sharp looking and easy to use. This is a great microwave for all essential needs. Not huge, but big enough for any large bowls I might want to put in. A 9×13 pan won’t fit, because of the rotation, but a 9″ square will be fine. The exterior is really sharp. Not just black glass, more like a mirror finish. Looks good in my contemporary kitchen. The controls are easy to use. I had a Panasonic years ago, and it was the best microwave I’ve ever had. Hoping this one will be just as good. Worth the money.

    Great, but… Great cooking performance except for two things;
    1) The gray numbers and writing on the controls are hard to read against a black background, especially in a dimly lit room. I don’t understand why they didn’t make the writing white.
    2) The hum of the motor is louder than other microwaves we’ve had in the past.

    Fantastic Compact Microwave with Plenty of Power. Reading reviews are a mixed bag. You see people that love the product, and others absolutely hate it. I must say in my experience, this is a great microwave. I picked it up to replace an aging Magic Chef and I have to say, it has been a great purchase. I mean if the company is good enough to reliably power my car, it’s good enough to cook my food – fast and evenly.

    The size is ideal for our needs. It fits nicely on a metal Inter Metro shelf that you get from the Container Store. The oven itself fits a dinner plate with room to spare. You can even silence it in case you want to press the buttons and hear nothing.

    I’ve read complaints about the microwave interfering with wireless technology but I’ve experienced none of it. And I live in a dense urban environment with hundreds of WiFi routers, 5G antennas and Bluetooth devices all around me. I may be glowing white, but no interference issues whatsoever with any of my devices while the oven is doing its thing.

    I’ve also read complaints that the oven light is too dim? Maybe some people bought the “bring your own light” model. Believe me, it’s not an issue.

    So with that, I encourage you to look no further and buy this great little microwave.

    Light ‘em up. Noisy! Loud! If, you are tall, it is hard to read the keys, therefore not designed for tall older folks. Positively, cooks to satisfaction. All keys should be lit up like the clock. And, the points, size of the print, should be increased. Otherwise, it’s difficult to read.

    Happy Customer. My existing Panasonic microwave stopped working on December 2, 2022
    After comparsion shopping online Walmart had the model of Panasonic Microwave I wanted such as table top model no NN-SN686S, wattage 1200 watt, 1.2 cu ft, with new functions on touchpads (popcorn with 3 options) and plus quick 30 along with turntable. Walmart had the best price than the other on line sites. Ordering online was easy, the price was a plus and delivery to my home with 2-3 days was appreciated. I received the microwave oven in 1 day on December 3rd. Thanks

    Excellent Microwave. This is a wonderful microwave. It is just the right size for me, the dimensions given are very accurate. The 1200 W rating is excellent. It heats things quickly and get things quite hot in a reasonable amount of time. The door opens and closes very smooth and easy. The touch pad is very responsive and needs only a light touch. This is a great microwave. Very glad I purchased it.
