Introduction to the Breville BMO870 3 in 1 Combi Wave
The Breville BMO870 3 in 1 Combi Wave is a premium countertop cooking appliance that combines a microwave, convection oven, and grill in one compact unit. Designed for users who want speed without sacrificing cooking quality, it is built to handle everyday reheating, baking, crisping, defrosting, and air-fry-style cooking with fewer appliances taking up space in the kitchen. This makes it a strong choice for busy households, apartment kitchens, and anyone looking for a versatile all-in-one microwave oven.
One of its biggest advantages is the combination cooking system, which allows faster cooking while delivering browning and crisp finishes that standard microwaves cannot provide. The Breville BMO870 3 in 1 Combi Wave also appeals to home cooks who want more control over texture and doneness, thanks to inverter technology, sensor cooking, and multiple preset functions. It is especially useful for families, meal preppers, and users who want to reheat leftovers without drying them out.
The unit is typically positioned in the premium price category, with market pricing commonly ranging from about $500 to $800 depending on retailer, finish, and region. Availability is generally strong through appliance stores, major online retailers, and the Breville product lineup, though pricing can vary by sales period. If you are comparing the Breville BMO870 3 in 1 Combi Wave with conventional microwaves, the main tradeoff is cost versus capability: you pay more, but you gain multiple cooking methods in one appliance.

For buyers comparing alternatives, the Breville BMO870 3 in 1 Combi Wave is best for households that want an all-purpose cooking solution rather than a simple microwave. It offers better versatility than budget combination ovens, but the premium pricing means it is not the most cost-effective option for minimal users.
Customer Reviews and Real-World Feedback on the Breville BMO870 3 in 1 Combi Wave
Customer feedback for the Breville BMO870 3 in 1 Combi Wave is generally positive, with many users praising its cooking versatility, modern design, and reliable reheating performance. Average ratings commonly fall in the strong 4-star range, with many owners highlighting the convenience of having a microwave, oven, and grill in a single machine. A frequent compliment is that food heats more evenly than in typical microwaves and that toasted, baked, and crisped results are noticeably better than expected from a countertop unit.
Common complaints usually focus on price, size, and the learning curve for selecting the best mode for each type of food. Some users also mention that the unit takes time to master if they are used to basic one-touch microwave controls. Typical testimonials describe it as “worth it for the convenience” and “a great space-saving upgrade,” while critical feedback often notes that it is expensive if used only for reheating.
Overall, the Breville BMO870 3 in 1 Combi Wave is recommended for cooks who want premium flexibility and are likely to use the full feature set. It is less suitable for buyers who want the cheapest microwave available.
