Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
One whitelisted tester covers this exact model with hands-on measurements: Wirecutter names the Panasonic NN-SN686S its top-pick microwave, measuring the fewest hot and cold spots and the most accurate sensors of any model tested. Consumer Reports (non-whitelisted) and Reviewed's brief, undated product capsule were the only other coverage found. (1 sourced review, 1 lab-tested.)
Praised: Most even, precise heating — fewest hot and cold spots of any model tested; Large, responsive door-open button rated easiest and most pleasant to use; Accurate sensor-reheat plus 12 sensor-cook modes that worked well.
Flagged: No instant-start express settings (must enter time/power then press start); Repair requires shipping to a service center or finding a certified shop; Frequently out of stock.
Only one whitelisted tester, Digital Trends, published hands-on prose on this exact model, and it is a pre-launch first-look, not a lab test, so no measured benchmarks exist. It praises the quiet soft-close door, easy LCD controls, and reliable results across a dozen recipes. Reviewed and TechGearLab tested different Breville microwaves, not the Combi Wave. (1 sourced review.)
Praised: Quiet operation, with a soft-close door that pulls itself shut almost silently; Easy to operate via the LCD menu, six function buttons and two main dials; Reliable, successful cooking across varied recipes (air fries, panko shrimp, banana bread, brownies) with no failures.
Flagged: Some foods (air fries, banana bread) needed the 'A Bit More' button for extra time; Coverage is a qualitative pre-launch first-look with no lab measurements (noise, wattage, defrost, etc.).
