Microwave ovens come in a variety of styles to fit all your home decor needs. It doesn’t matter if we are talking about otr microwaves or countertop microwaves. Some are black stainless steel, others are shiny stainless steel finish for the modern kitchen. If you have retro decor, there is also a retro microwave for you. Many people prefer a stainless steel exterior. It is easy to find the right model that blends right into your kitchen and matches your, espresso machines, food processors, coffee makers, air fryers and other appliances. Many of today’s models can even work with other smart home devices if your home is a smart home.
A microwave’s wattage tells you how much power it has, and more wattage means your food will cook faster and more evenly. You’ll typically see microwaves between 500 and 1,200 watts. Be aware that microwaves with fewer than 700 watts are generally underpowered and add time to the cooking process. These models are a good option for people limited by a budget, looking to save space, or willing to wait a few extra minutes. If you want a fully functional microwave to cook meat and vegetables, look for models with 1,000 watts or more.
If you’re looking for a traditional microwave that won’t disappoint, this is our recommendation. It’s standard in visual design, and its 1.1 cubic feet internal capacity strikes a nice balance between conserving space and still fitting a reasonable amount of food. It won’t be the centerpiece of your kitchen; rather, it will simply blend in and do its job reliably well.

It still offers excellent capabilities like nine different menu buttons for specific foods, but the design makes things easy without the need to learn any new controls. The model also sports an interior, Teflon-like finish called EasyClean, which is designed to allow you to wipe down spills easily (although if you are wondering how to clean a microwave that’s truly dirty, we’ve got some more detailed information for you). The model also comes in both standard and black stainless steel, although the black stainless version is a little more expensive, so you may lose out on the excellent cost savings that come with this Kenmore if you go for that option instead. It has 10 power settings.
The Toshiba EM131A5C-BS handles all your basic tasks and balances counter space with a roomy capacity. Available in either black or silver stainless steel, this countertop microwave has an interior capacity of 1.2 cubic feet while measuring just over 20 inches wide and 17 inches long. Its 1,100 watts of power can be adjusted with 10 power settings, and customers agree that it cooks food evenly and quickly. The unit also is equipped with sensor cooking and two defrost settings, though some people found that not all of the pre-set cook modes worked as expected and the microwave defrosted too aggressively for some meats. Still, this Toshiba countertop microwave has a solid reputation for being easy to use and reliable.
This mistake can happen when buyers get a little too excited. When all you’re focused on is, “When did the microwave come out?” and “Does it have the latest features?”, then you’re ignoring how you currently use microwaves, which is just as important. If you don’t use any of those menu buttons or defrost features now, you probably won’t use them on a new microwave, either. Buy microwaves based on how you like to use them, not on the latest flashy features.
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.
It still offers excellent capabilities like nine different menu buttons for specific foods, but the design makes things easy without the need to learn any new controls. The model also sports an interior, Teflon-like finish called EasyClean, which is designed to allow you to wipe down spills easily (although if you are wondering how to clean a microwave that’s truly dirty, we’ve got some more detailed information for you).

The defrost options (varying by type or weight) are ideal if you want to warm something up with the microwave before cooking with the convection setting. If you have a busy kitchen and want multiple ways to cook foods (instead of just nuking the occasional popcorn bag), Cuisinart delivers. About the only thing that it’s missing is the ability to set power levels, but with all these other features, that’s a minor quibble to be had.
Countertop microwaves are some of the most popular models, and there are many options to choose from. They are quick and easy to install—just plug them in—and you can move them around as needed, making them a top choice for renters. The main downside of countertop microwaves is that they take up valuable counter space, which can be frustrating if you have a small kitchen. 
For our 2018 update, we ran a series of tests on 12 microwaves. First, we created our own version of a heat map by cutting a piece of parchment paper to fit the turntable of each model and completely covering it with a layer of plain mini marshmallows. Then we nuked it on high for 2 minutes until the marshmallows began to brown. By looking at the underside of each piece of parchment paper, we could see the pattern of browning and determine how evenly the microwaves generated heat (for more on how microwaves work, see above).

Next, we tried defrosting a 1-pound portion of frozen ground beef in each microwave, using the automatic defrost setting on the models that had this feature. Some units gave prompts to flip the meat, which we did. When the time was up, we broke apart each block of meat with a fork to see if it was completely defrosted. None of the microwaves were particularly great at this task. Every model at least slightly cooked the edges of the ground beef we attempted to defrost. (Best practice is to slowly thaw meat in the fridge, or relatively quickly under cold running water.)

Over the range microwaves are a different sort of beast – they typically have extra features like air flow fans underneath their base (used to clear smoke off stoves, which can add to the cost) and tend to be larger than other options. With 300 CFM of air flow and two speed fan controls, this GE model can handle over the range tasks as necessary. That spacious 1.6 cubic ft countertop microwave is also great for larger dishes.
For an over the range microwave, you need the right kind of airflow for your setup, and you may need additional features like the ability to control oven range lights. Over the range units are specifically designed for these tasks, but they vary from model to model, so don’t get complacent when buying. Know what you need to keep your stove clear of smoke first!
You’ve probably heard of a convection oven, but did you know that there are convection microwaves, too? These specialty appliances use the same technology as their oven counterparts: A fan blows and circulates hot air into the microwave, helping to cook food faster and more evenly. Convection microwaves can also brown or crisp food, similar to a traditional oven. 
The 1.2-cubic-foot Toshiba EM131A5C-BS is a great option for anyone who wants a slightly larger microwave with more express cooking options. Initially, we found these additional controls less intuitive to operate than our main pick, the Toshiba EM925A5A-BS, but after a few tries, we got the hang of it. Like our other pick, this Toshiba has a mute button for silencing the beeping. Its 12-inch-wide turntable is large enough to accomodate most dinner plates or a 9-inch square baking dish, but it’s too small to fit a 9-by-13-inch casserole dish. The 1.2-cubic-foot Toshiba comes in a stainless steel or black stainless steel exterior.
When you add in the competent wattage and the internal space, which is large enough for the bigger plates in your home, it’s tough to see what this Panasonic model doesn’t do right. This 2.2 cu ft microwave is a winner. Even the design is pleasantly modern and easy to clean in case of grease or stains. This microwave really does impress on every level…but it’s not an over the range model, which may limit your options.
All microwaves use this same core technology, but today, there are many models available that come with a variety of additional features. For instance, many products have pre-programmed settings to cook common foods, as well as various cooking methods, such as steaming and grilling. Depending on what size and features you want, you can spend anywhere from $20 to $2,000 on a new microwave. 
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.
This invention relates to heating systems for dielectric materials and the object of the invention is to heat such materials uniformly and substantially simultaneously throughout their mass. ... It has been proposed therefore to heat such materials simultaneously throughout their mass by means of the dielectric loss produced in them when they are subjected to a high voltage, high frequency field.
