## 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. (1 sourced review.)

**Whirlpool WMH31017HS 1.7 Cu. Ft. Over-the-Range Microwave** — One whitelisted tester, NYT Wirecutter, hands-on tested this microwave, naming the Whirlpool WMH31017 (the HS is its stainless finish) its runner-up over-the-range pick. It heats evenly with a quieter fan than the GE top pick, but lacks express and sensor controls. No other whitelisted outlet had a hands-on review of this exact model. (1 sourced review.)
