## What reviewers say

**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.
