To find the best microwave, we tested 10 microwaves in our Kitchen Appliances and Technology Lab, checking how well they melted cheese, "baked" potatoes, reheated food, defrosted frozen food, popped popcorn, and cooked vegetables. We also looked at their ease of use — controls, opening the doors, view-ability inside, cooking alerts, and cleaning. For models with convection and/or grill capabilities, we tested their ability to roast chicken, bake cake, and broil steak, then noted the surface temperatures. Based on our extensive tests, we've rounded up our top-rated microwaves:

There are two types of microwave vent systems: recirculating and external. Recirculating vents simply pull the air up into the appliance, run it through a filter to remove impurities, then push it back out into your kitchen. This type of ventilation system is ductless and easier to install, but it doesn’t perform as efficiently as external ventilation. 
The Toshiba EM131A5C-BS is best for anyone seeking out a slightly bigger, more powerful 1,100-watt microwave. It looks similar to our main pick, the Toshiba EM925A5A-BS, but offers a few more express controls for specific tasks like cooking bacon, defrosting frozen muffins, and making oatmeal. It also has a Soften/Melt button for butter, chocolate, cheese, and marshmallows. However, we found these additional controls less intuitive to operate than what our other pick offers, and we don’t think they’ll get used often. This Toshiba also boasts a cooking sensor that’s supposed to automatically determine when your pizza or potato is hot enough, but it didn’t perform any better than the 0.9-cubic-foot Toshiba, which lacks this feature. The 1.2-cubic-foot Toshiba has a larger 12-inch turntable, so it will fit most dinner plates and a 9-inch square casserole dish. Like our main pick, this model is available in a stainless steel or black stainless steel exterior.

The Quick Touch is a little expensive at $250. Amazon reviews also warn that the words printed on the buttons can wear off after years of use … but we actually liked the implication that this microwave will last long enough for some surface-level wear. If you’re going to pay more for an appliance it should be long-lasting and awe you with its usability and features — the Quick Touch did that for us.
In 1947, Raytheon built the "Radarange", the first commercially available microwave oven.[13] It was almost 1.8 metres (5 ft 11 in) tall, weighed 340 kilograms (750 lb) and cost about US$5,000 ($56,000 in 2018 dollars) each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. The name was the winning entry in an employee contest.[14] An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS Savannah. An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000 ($19,000 to $28,000 in 2018 dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952.[15] They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($12,000 in 2018 dollars), but it did not sell well.
Microwave ovens are a time-saving addition to the modern kitchen. From handy countertop microwaves to convenient over-the-range models, there’s a style for every space. For even better cooking results, opt for a convection microwave oven that combines fast cooking power with the browning and crisping ability of a traditional convection oven.
