Our Verdict

The Black+Decker EM720CB7 earned one of the lowest scores out of our lineup of the best microwaves, struggling in quite a few of our tests. It did very well in our defrosting test with the ground turkey, but that is far from enough to redeem its multiple poor showings in other tests. All in all, we generally think you could probably find better options out there for your kitchen.
REASONS TO BUY
Did well at defrosting
Fairly inexpensive
REASONS TO AVOID
Struggled with some frozen foods
So-so heating results

Pros Did well at defrosting, fairly inexpensiveGood at defrosting meatEasy to use, relatively inexpensive, excellent with prepared frozen itemsGood at reheating, does well with premade frozen foodsStylish retro look, available eco mode
Cons Struggled with some frozen foods, so-so heating resultsNot the most convenient to use, heating performance could be betterStruggled to defrost the ground turkeyDidn't defrost frozen turkey wellDial for timer interface, uneven heating
Bottom Line This product failed to impress us too much, ranking close to the bottom of the overallThis product pairs average results with an average price, failing to stand out from the competitionThis product had mixed results overall, failing to distinguish it all that much from other productsThis larger product did decently well but we don't think it quite matches the performance of the top-tier modelsThis product is great if you value the retro look more than overall performance

Our Analysis and Test Results

Aside from its exceptional result at defrosting the one-pound brick of ground turkey, there was very little about this microwave's performance that made it stand out from the best microwaves. Even then, other models still outperformed this model, making it difficult for us to find a reason to recommend this appliance above others.

Likes


As we said before, the main thing we like about the EM720CB7 is how well it did in our defrosting metric. For this test, we used a one pound square of frozen ground turkey. Following the manufacturer's directions for defrosting, we were able to defrost 12 ounces of the turkey at the end of the microwave's defrost cycle. None of the meat was cooked through, and the remaining 4 ounces of turkey was easily broken apart — enough that we wouldn't think twice about tossing it all in a pan to start browning it.

The Black+Decker also did decently well at reheating the canned soup, but this isn't rare; nearly every model we tested did a good job with this test. It got the soup to the perfect serving temperature following the heating directions for this microwave's power rating. In the heat map and speed tests, this model delivered average results. We used marshmallow cream spread out on parchment paper to make a map of heating intensity. This microwave evenly burned the center and middle rings. The outer ring was just getting toasted with a few completely uncooked spots.

The top of the heat map looked much more consistent.

For the speed test, we heated 125 mL of water for 45 seconds and measured the temperature increase to determine scores. This microwave raised the temperature of the water by 73.4°F — fairly typical results.

The Black+Decker EM720CB7 also did well quite well with the Hot Pocket, heating the left, right, and center areas within a few degrees of each other.

Dislikes


The EM720CB7, unfortunately, delivered poor results in our other two heating tests. Neither the plate of leftovers nor the pizza were warm enough for serving, and both were heated very inconsistently.

The EM720CB7 also failed to properly and evenly heat the frozen burrito and the lasagna. After following the directions, the miniature lasagna was far from a satisfactory serving temperature, with an average temperature difference of 29°F between zones. The burrito had a similar variation between areas, with the middle failing to reach the recommended temperature.

We weren't thrilled with how much this product slides around during normal use, and it has so-so internal lighting. We also didn't find the presets to be super effective. We tried out the popcorn function, which left a lot of kernels unpopped. None were burned, at least.

Should You Buy the Black+Decker EM720CB7?


Though any of the microwaves in our test will get the job done (eventually), many people shopping for kitchen appliances want the best products available, and we don't think the Black+Decker EM720CB7 is that — particularly if you are seeking speed or uniformity in your microwave cooking endeavors.

What Other Microwaves Should You Consider?


Though this is a small, fairly affordable model that is suitable for small kitchens, we'd suggest the Toshiba EM131A5C for a full-size microwave that earns its keep as a premium model.
