Panasonic NN-SN686SR Inverter Microwave vs Toshiba EM131A5C-BS
Which should you buy? Our verdict on both, pulled from our full The Best Countertop Microwaves: 4 Compared (and One to Skip) comparison.
The Panasonic's inverter and reliable sensor make it the most consistent everyday heater at a fair price. The Toshiba is the value runner-up, giving up some evenness but very little else for meaningfully less money.

Panasonic NN-SN686SR Inverter Microwave
Buy itThe most consistent heater of the group, thanks to genuine inverter power and a reliable sensor.
- Inverter delivers steady low power instead of pulsing full-blast, so reviewers report fewer rubbery edges and cold centers
- Genius humidity sensor reheats and defrosts with little guesswork
- Mid-size cavity that reviewers say fits most dinner plates and casserole dishes
- Owner reports skew strongly positive on long-term reliability
- Mirror-finish door and keypad show fingerprints
- Beeps are loud and owners report no full mute

Toshiba EM131A5C-BS
Buy itThe value pick: a well-sized sensor microwave that does the basics well for budget money.
- Humidity sensor and one-touch presets that independent testing found genuinely useful
- Strong defrosting performance in hands-on tests, with evenly thawed edges
- Owners report a mute function for the beeps
- Removable, easy-clean interior and a generous turntable
- Standard magnetron (no inverter), so heating can be less even than the Panasonic
- A minority of owners report an unresponsive touch panel or clock drift over time
