Japan's Sharp Corporation began manufacturing microwave ovens in 1961. Between 1964 and 1966, Sharp introduced the first microwave oven with a turntable, a feature that promotes convenient even heating of food.[16] In 1965, Raytheon acquired Amana. In 1967, they introduced the first popular home model, the countertop Radarange, at a price of US$495 ($4,000 in 2018 dollars).
Its high-tech capabilities don’t seem to cause complications, and reviewers find it easy to set up. A visually impaired reviewer writes: “I’m always hesitant when I buy something that needs to be paired with something else in order to get the full benefit of it. Sometimes, something on the screen needs to be entered which we can’t see. There might be on-screen prompts or whatnot. This microwave had none of that. It was a cinch to set up and works beautifully.” Others love its small size. “We have a VERY small kitchen with barely any counter space so I was very pleased with how compact it is,” writes one commenter.
Food and cookware taken out of a microwave oven are rarely much hotter than 100 °C (212 °F). Cookware used in a microwave oven is often much cooler than the food because the cookware is transparent to microwaves; the microwaves heat the food directly and the cookware is indirectly heated by the food. Food and cookware from a conventional oven, on the other hand, are the same temperature as the rest of the oven; a typical cooking temperature is 180 °C (356 °F). That means that conventional stoves and ovens can cause more serious burns.
The Breville’s accuracy and customizability were unmatched in testing. Because microwave heat conducts from the outside in, you’ll usually get rubbery edges if you don’t lower power to allow the heat to seep in further. But with the Breville, if something starts boiling over, you can use its power level and time dials in the midst of cooking and let the heat penetrate.
Our microwave buying guide has everything you need to make the right choice for your kitchen, but if you buy on Amazon, check out every Amazon reviewer for your favorite models and see what they had to say. After all, they have already purchased it. To see it in person, go to a store like Home Depot and get a first-hand look at all of their microwave ovens, overtherange microwave
Not Measuring Before You Buy: We can not reiterate this enough: always measure and compare your space with the dimensions of the microwave you plan to buy beforehand. This is absolutely necessary if you have a cabinet or space specifically for a microwave, but it’s also important if you are buying a counter microwave. The best cheap microwave in the world isn’t going to you much good if it doesn’t fit in that corner when you’re short of kitchen space.
Adoption has been slower in less-developed countries, as households with disposable income concentrate on more important household appliances like refrigerators and ovens. In India, for example, only about 5% of households owned a microwave in 2013, well behind refrigerators at 31% ownership.[24] However, microwave ovens are gaining popularity. In Russia, for example, the number of households with a microwave grew from almost 24% in 2002 to almost 40% in 2008.[25] Almost twice as many households in South Africa owned microwaves in 2008 (38.7%) as in 2002 (19.8%).[25] Microwave ownership in Vietnam was at 16% of households in 2008—versus 30% ownership of refrigerators; this rate was up significantly from 6.7% microwave ownership in 2002, with 14% ownership for refrigerators that year.[25]
This microwave’s voice-control integration with the Amazon Echo is a big selling point among reviewers. Hundreds of people mention Alexa in their reviews, and commenters use it in some unique ways: “It’s great and has some unexpected uses besides the coolness factor. For example, sometimes I’ll reheat a cup of coffee while working at home and forget about it. The Echo alarm in my room lets me know the microwave is done. If I forget about it, I can just say, ‘Alexa, reheat for one minute,’ and it goes. Verbal confirmation from the Echo is a great feature.” Another reviewer shares, “Surprisingly, the voice command is more fluid to use even than using the buttons we all are so used to.”

Toshiba makes microwaves in other sizes too: 1.2, 1.5, and 1.6 cubic foot, all of which have slightly different internal parts and control panels. However, after testing the 0.9 and 1.2 cubic foot models for this guide, we think the former is the best for most people because it’s simpler to use and takes up less space. You can’t fit a 9-by-13-inch casserole dish in the cavity of the 0.9-cubic-foot unit, but its 10.5-inch turntable is still wide enough to fit an 11-inch dinner plate or a 9-inch square casserole dish. At 900 watts, the 0.9-cubic-foot Toshiba also packs a lot of power for its size. It measures 19.1 by 16.1 by 11.5 inches, so it’s a nice midsize option that falls in between the two other microwaves we recommend. And while we realize the control panel looks straight out of the ’90s, the microwave is available in a stainless steel or black stainless steel exterior, so it will fit the aesthetic of most kitchens.
In our experience, sensors and other smart features make microwaves more useful than they’ve been in the past. Technology that can detect the moisture in your food or note the size of what you’re cooking – and making cooking decisions for you based on that data – is almost always worthwhile. Just remember to give those sensor cooking features a try instead of ignoring them! It might make your baked potatoes perfect.

Our microwave oven tests found big differences in overall performance among models. To test heating we warm up mashed potatoes, and we use frozen ground beef to test defrosting. We also test speed of heating, noise, and ease of use. We measure usable capacity, too. (Manufacturers often include space you can't use.) Plus we test how well the over-the-range models vent.
The Breville also makes it simple to customize based on the size, weight, and nature of the food you’re cooking. There’s even a reheat option for pizza. Alternatively, you can leave it up to the Breville’s sensor to detect moisture and temperature and accurately reheat. When we tried this in our testing of beverages and with our own lunches, it was surprisingly accurate.

In the 1960s,[specify] Litton bought Studebaker's Franklin Manufacturing assets, which had been manufacturing magnetrons and building and selling microwave ovens similar to the Radarange. Litton then developed a new configuration of the microwave: the short, wide shape that is now common. The magnetron feed was also unique. This resulted in an oven that could survive a no-load condition: an empty microwave oven where there is nothing to absorb the microwaves. The new oven was shown at a trade show in Chicago,[citation needed] and helped begin a rapid growth of the market for home microwave ovens. Sales volume of 40,000 units for the U.S. industry in 1970 grew to one million by 1975. Market penetration was faster in Japan, due to a re-engineered magnetron allowing for less expensive units. Several other companies joined in the market, and for a time most systems were built by defense contractors, who were most familiar with the magnetron. Litton was particularly well known in the restaurant business.
