Panasonic NN-SD997S microwave

The Good The Panasonic NN-SD997S's impressive internal capacity will feed a large family and the sensor functions generally deliver. Also, its high wattage yields quick results.

The Bad The inverter technology claims to make "delicate foods" like eggs and fish better than its non-inverter competition. It didn't.

The Bottom Line If you're interested in the inverter tech angle, you may be disappointed. But if you don't expect to get artisanal omelets from a microwave, it's still a solid choice for a large, midprice countertop model.

Review

Midprice microwave boasts high-end features

I tested the $300 Panasonic NN-SD997S with inverter technology against three other countertop microwaves: the $290 Sharp Convection Grill R-820JS, the $279 Whirlpool WMC50522AS, and the $219 Amana AMC2166AS. As the most expensive of the four models, it was the microwave to beat.

To test it, I popped popcorn, baked potatoes, heated lasagna and macaroni-and-cheese frozen dinners, reheated pizza, defrosted chicken, boiled water, cooked burgers, and made omelets -- all in this microwave. It also means I endured a lot of taste tests (with varying levels of deliciousness) to deliver you a comprehensive review. You're welcome.

For the most part, I am really happy with this microwave. It looks sleek and professional and it's a good deal -- $300 for 2.2 cubic feet of capacity and 1,250 watts. You're definitely getting a powerful, capable appliance for a midrange countertop price. The inverter technology and sensor modes disappointed on occasion, but I'm going to make a bold statement about microwave functionality: every single model is going to require some trial and error; the tech for flawless moisture sensors and perfect default settings just isn't there yet. Fortunately, this particular model didn't require much tweaking, so I consider that a relative success.
