What reviewers say

Sourced tester consensus for each — the "what people who used it think" layer, not just specs.

Breville Combi Wave 3-in-1 (BMO870BSS)

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.).
