Breville Combi Wave 3 in 1 (BMO870) review

The Breville Combi Wave 3 in 1 scores highest on quality but ranks fourth because of its $499.95 price. It is a microwave, convection oven and air fryer in one cabinet, so it can take the place of a toaster oven and a separate air fryer. Breville's Element IQ system steers power where it is needed, and the Power Smoothing Inverter delivers steady power for even reheating and gentle defrosting. There are 19 smart presets, including Smart Cook, Smart Reheat and Smart Defrost, plus a Fast Combi program that uses convection, grill and microwave together and a Cook from Frozen program that switches between them in stages. Breville says the soft close door is 80% quieter and operation is 50% quieter, and there is a mute button and child lock. A Combi Crisp Pan and trivet come in the box. The trade-offs are price and size: it needs 20.5 x 20.1 x 12.6 inches of space, and Breville's US page does not state capacity or wattage. We compared documented features and published prices and did not run cooking tests.
