    • He Thought I Was Crazy—Now We Both Love It!
Review Image by Maryjane07
My partner thought I was crazy for spending this much on a microwave, but now we both absolutely love it! It heats food quickly and evenly, and the sensor-reheat button is my favorite feature. It measures the food and automatically determines how long it needs to cook—and honestly, it works better than the instructions on most food packages. Everything comes out heated perfectly without having to guess or keep adding more time. It also looks sleek and modern in our kitchen. Definitely worth the money! ... show more

    • Forget complicated settings; ‘Sensor Reheat’ works well.
Innovative design, features the first real advances in 50 years of microwave ovens. It doesn’t have a turntable, but it doesn’t need one, and its absence lets it be considerably smaller. The “Sensor Reheat” function works well. The few times I tried to second-guess it, I was wrong, and it was right. It is somewhat of a relief to not have to guess how long it will take to reheat leftovers — just put them on a plate, put them in the oven, and press the button. My partner tried using it to defrost something and he said it came out perfectly. Temperature sensors are relatively cheap these days, so to have a microwave oven actually measure the temperature across 64 points and figure out when “hot” is “hot enough” is just a great advance. There are two things to be aware of: 1. Because it looks at the food to determine the temperature, you CANNOT use a cover. I used to use a cover to help prevents spills and splatters….well, without a turntable, it’s just a nice flat cube that’s easy to wipe down. 2. They aren’t kidding when they say that all-cheese on the surface will mislead the sensors. So, don’t cover something with cheese and expect to work correctly. It’s expensive, yes, but the whole “push the button for forget it” factor _really_ makes up for that, plus the reclaimed counter space. So, overall, I really recommend this unit. Best improvement in a microwave since Amana first put them in kitchens more than a half-century ago (my mother had one, I was there). ... show more

    • Best Microwave Ever!
Though it came with a dent, we chose not to return it as the space for it did not show the dent. It is by far the best microwave we have ever owed! No hot spots/cold spots when heating foods. Super easy to use, but very different than any conventional microwaves. We were a bit unsure on the drop down door but it is THE BEST! ... show more

Day one this thing was incredible right out the box. I am not a big fan of microwaves, but this is more than a microwave. I made dinner in record time thanks to the reheat sensors, and I didn’t have to think about it - at all. It’s insane how efficient the cooking is, and how even everything came out. 1200 watts of power (🎵 roadrunner roadrunner 🎵…) plus the hidden technology make this thing worth every penny. I love the dial - when setting times or cranking the power settings for the sensor cooking, it works great. When you put in a mug of liquid (tonight I reheated fish broth), you hit beverage and it brings it up to the right temp, then stops. When you put in a plate of food, you just hit start and it reheats it evenly to the right temperature and then stops. It’s the perfectly automated microwave, yet you still have manual control for items that need a cook time, power settings, etc. It looks cool, and the drawer and no-turntable design make this thing a total winner. I did try defrosting ground beef with the automatic settings - but that’s not how it’s recommended to be done in the manual, which brings me to my final point: Because this thing is an advanced piece of technology, you really wanna crack open the manual and get familiar with the different settings, their use, and what works and doesn’t work with the automatic sensor functions. I kinda wish it had a built-in air fryer like its counterparts in Japan, but hey, I’m just stoked to be stoked on owning a microwave. ... show more

    • Get it if you're willing to pay for the looks.
This is a great microwave, but there's a Panasonic 1.2 cu. ft inverter microwave that's less than 1/3 of the price of this one. So the question is whether this Genius 2.0 sensor and cyclonic inverter worth 3x? The sensor works amazingly well for certain foods - solid and fairly homogenous items work well. Bread, or cooked, meat-filled buns reheated really well, whether they came out of the fridge or freezer, with the single press reheat feature. Spaghetti with tomato sauce however, always seems to overheat, and always splatters all over the place and requires a wipedown. I think the vision is great, a single button/dial is really nice when it works - you put in your food, press the button/dial to start, and turn it to adjust how hot you want the food. But the "how hot" has pretty inconsistent results depending on the food, and often the lowest setting may still be very hot. The other buttons on the front give you an idea of where the "Genius" needs help. The "Microwave" button is a fallback to the classic time-based microwave interface, you turn the dial to set the time. The "Defrost" mode lets the microwave know to stop when the food is defrosted, instead of making it hot. It would have been great if the normal reheat mode just let you dial down the temperature to "Defrost". There's a "Beverage" mode, which suggests the normal "reheat" gets confused by liquids. A "Popcorn" button exists specifically for popcorn - probably because Japanese love their popcorn. And finally the "Quick 30" button to show how Panasonic has had the dumbest 30-second button for decades (For most other microwaves, it's a convenient single press to run the unit for 30 seconds, but Panasonic has always required the user to press Start after). It would have been really easy for the "Microwave" button to default to 30 sec instead of 0, and not need this button. For a premium priced product, it only works great sometimes, and the interface is aggravating. The best part of this microwave is the looks. It does look better than any other single-function microwave out there. The oven-door design has the effect of making the cavity wider, but shorter than traditional designs with the control panel and electronics on the side. This works great for most meals, where your dish and food tend to be much wider than they are tall. The downside to this is that this was really designed for counter height use. Put this higher and it's awkward to get a plate over the door. Put it too low, and the controls on the bottom are hard to see and reach for. ... show more

    • Totally worth it - 3 months of use so far
Excellent value for someone who takes atleast minimal care of their equipment. Put the food, press the button and never worry about overheating, underheating, splatter, spill, just the perfect amount of heat which is again adjustable with a knob anytime during the operation. It has made my meals so much more enjoyable. Basically a massive time saver in the long run and perfectly heated food to eat ... show more

    • New microwave; poor QC? Didn't work from the start.
At the time of writing this review, all of the other reviews are all for a free product. I’m one of the first (on Amazon) to purchase the microwave on my own. I liked the look, liked the specs and jargon, and hoped for the best. It arrived, I set it up, and it... wouldn't function. No matter the setting, it would start cooking for 0.5 seconds, then shut down and show the cooling fan symbol. What?? It's brand new! Ok, let's talk to Panasonic help. Panasonic says it's likely an internal issue, probably something with the inverter. They want me to send it in for repair/replacement... no, no I don't think I will. It's a BRAND NEW microwave, I'll return it to Amazon. Why does your $400+ microwave require repair upon arrival? It does look nice, but the dial on mine was extremely poor quality. You would expect a nice, heavy duty metal dial with solid click feedback, but instead, the dial that I received on mine was cheap, plastic, and had no distinct movement or clicks. It seemed like it could have used some lubrication or something. I don't know how the other reviews don't mention the dial, mine is really bad. It might be a good microwave, when it actually functions from the factory. To be honest, even though it looks nice, it does not seem like a $400+ value microwave just from the plastic finish and poor dial alone. So, it looks good, it might function well when it does work, but the finishes and dial quality don't feel high end. ... show more
