What to Look for in a 3-in-1 Countertop Appliance

Cooking Versatility: More Than Just a Microwave

A true 3-in-1 should handle microwave reheating, air frying, and convection baking without compromising any function. The Breville Combi Wave uses an Element iQ system that distributes power intelligently across these modes. Look for presets that cover common tasks like melting chocolate or reheating pizza, as well as combination cooking that uses microwave and convection together to speed up meals. The Smart Cook, Smart Reheat, and Smart Defrost presets take the guesswork out of daily use.

For those who want maximum flexibility, the Ninja Foodi 10-in-1 reviews show another approach with even more cooking functions, though it occupies a different footprint.

Performance and Speed: How Fast Does It Cook?

Speed matters, especially when you are hungry. The Breville Fast Combi function combines convection, grilling, and microwave to cook dishes faster than a traditional oven. Its Cook from Frozen setting lets you skip thawing and still get evenly cooked results. In our evaluation, the microwave reheated leftovers in minutes without drying edges, while the air fryer produced golden fries in about 15 minutes. The inverter technology ensures smooth, even power delivery for consistent results.

Ease of Use and Cleaning

Daily usability can make or break an appliance. The Breville features a soft-close door that operates quietly, and a mute button to silence beeps. The interior is nonstick and the included Combi Crisp Pan simplifies cleanup. Smart presets like Smart Cook and Smart Reheat take the guesswork out of settings. If you value intuitive controls, this model stands out. The child lock adds safety for families.

Size and Design: Will It Fit Your Counter?

At roughly 21 inches wide and 16 inches deep, the Breville Combi Wave is substantial but not oversized for a 3-in-1. Its brushed stainless steel finish blends with most kitchens. Consider your available space and whether you will need to move it frequently. The unit weight is manageable, but you will want a dedicated spot.

Final Thoughts

After thoroughly assessing the Breville Combi Wave 3-in-1, we believe it successfully merges three kitchen workhorses into one capable device. Its air fryer delivers crispy results, the convection oven bakes evenly, and the inverter microwave handles reheating and defrosting with precision. If you want to reclaim counter space without sacrificing performance, the Breville BMO870BSS Combi Wave 3-in-1 is a top contender. For those who prefer a separate air fryer and microwave, the Breville BMO870BSS Combi Wave 3-in-1 still offers excellent value as a standalone oven.
