Black+Decker EM031MB11 Review
This larger product did decently well but we don't think it quite matches the performance of the top-tier models
Even though it couldn't match some of the top products, this product scored quite well in our evaluations.

Our Verdict
The Black+Decker EM031MB11 scored pretty well in the bulk of our tests, earning an above-average overall score in our best microwaves review. It delivered respectable performances in our heating and frozen foods tests and scored well in our user-friendliness metric. However, we were unimpressed by its defrosting performance, and overall we weren't impressed enough for this model to earn a spot in our kitchen.

| Bottom Line | While this appliance did alright in our rankings, it just didn't match the performance of some of the better models | A full-size microwave that makes a delicious frozen burrito and quickly heats tasty leftovers | This appliance is a fantastic choice for anyone predominantly heating up frozen foods and seeking a larger model | A no-frills, compact, and affordable microwave that will take a little longer to cook your food | Ideal for those on a budget or with limited space, but this model falls short in terms of premium build quality and high-level performance across our evaluated metrics |

Our Analysis and Test Results
At 1.1 cubic feet, this model boasts a fairly large capacity. It also has one of the lower retail prices of the larger options, making it a decent choice if you want a full-sized microwave and are shopping on a reduced budget.

This microwave evenly heated up the potatoes and green beans on our plate of leftovers to within 5°F of each other, although the sausages came out just a bit warmer. The canned soup and the two slices of pizza came out nice and hot, consistently heated to the correct serving temperature.

The Black+Decker EM031MB11 also scored high in our tests of the manufactured frozen foods, impressing us most with frozen burritos and Hot Pockets. This appliance heated up the burrito's left, right, and center zones to within an average difference of 9°F of each other. It performed identically with the Hot Pocket, with our thermometers showing the same average difference.
There was just a bit of a cool spot in the center but all three regions were well above serving temperature with the Black+Decker. Credit: Laura Casner
We appreciate ease of use in our kitchen appliances, and this model had many of the convenience features we like. It has quick start features and a +30 seconds button that automatically starts the microwave. It also has decent internal lighting, and the preset functions seem to work very well.

We used the popcorn function, which popped nearly all the kernels without burning any.

Dislikes
Our biggest complaint about the Black+Decker EM031MB11 is its poor showing in our defrosting test. This microwave alerted us to flip the meat partway through the process, but it only managed to defrost just under 7 ounces of meat. It didn't cook any of the parts, but the remaining turkey was still relatively frozen and couldn't be broken up easily after we scraped away the completely defrosted parts.
The Black+Decker EM031MB11 also didn't score very well in our heat map test, leaving the outer ring of marshmallow fluff almost completely raw, while the middle ring was darkened considerably.
This product only gave lackluster results when heating up the individual serving of pre-made lasagna. The temperatures varied considerably amongst the six different digital thermometers we used, with the most significant temperature gap being 47°F between regions.
This model can be a decent bargain option as well. Credit: Laura Casner
Should You Buy the Black+Decker EM031MB11?
If you're hoping for a full-size microwave without a full-size price tag, this could be a good bet. However, performance-wise, we think that there are better options out there.

What Other Microwaves Should You Consider?
The Black+Decker EM031MB11 is a solid microwave, but it scored squarely in the middle of our tests. If you're looking for one of the best full-sized microwaves out there, we recommend checking out the Toshiba EM131A5C.
