This is the only countertop microwave we tested that clearly outperformed the mass of cheaper models, and it’s not too expensive, either. Otherwise, the features and controls are pretty similar.

Consumer Reports

CR’s take: For the price, you can’t go wrong with the midsized Panasonic NN-SN67HS. Speed of heating and defrosting evenness are both superb—the model notches Excellent ratings on both those tests. It evenly heats a dish of cold mashed potatoes, and our testers find it easy to operate without reading the manual. (We assess that because most people don’t check the instructions.) It’s a bit noisy when running on high, but typically you run your microwave in such short bursts that it might not bother you.

The Panasonic left the competition in the dust on our Heat Map test, which measures consistent and even heating of foods and earned the top score on heating overall.
