Overview
This Breville is notably spec-rich for a 1.1 cu ft unit: 1400W wattage, 19 power levels, and a combined convection-and-electric heating method give it more precise cooking control than most competitors in its size and price range. The brushed stainless steel finish and built-in classification suggest it was originally designed for countertop or built-in use, at 20.5 inches wide and 34 lb. Button controls keep operation accessible.
At $334.95 as a certified refurbished unit, it undercuts new Breville combination models by a meaningful margin. The 4.3-star average from 50 reviews is encouraging but statistically thin. Refurbished small appliances tend to see bimodal feedback: buyers either report a seamless experience or encounter the issue that prompted the original return. With only 50 data points, both outcomes are plausible.
The 19 power levels stand out as unusual, most residential microwaves offer 5 to 11. For buyers who do precision work like defrosting protein without cooking edges or tempering chocolate, that granularity is genuinely useful. For buyers who mostly reheat, it is excess capability they will never use.

Performance notes
The 1400W microwave output is strong for this cavity size, meaning everyday reheating tasks complete quickly. Convection mode circulates hot air, enabling browning and baking in a space that measures 20.5 inches wide. The 19 power levels, unusual in this category, allow genuinely precise control over heating intensity, which matters for delicate tasks. Physical button controls at this size and weight are reliable for daily use. At 34 lb, the unit is heavier than basic 1.1 cu ft microwaves, consistent with the additional heating components needed for dual-mode operation.
What buyers say
Fifty reviews at 4.3 stars indicates that most buyers who received this refurbished unit were satisfied, but the sample is too small to draw strong conclusions about long-term reliability or consistency across units. Certified refurbished products typically pass a functional inspection before resale, but buyer experience varies based on the history of individual units.
What does certified refurbished mean for this Breville microwave?
Certified refurbished means the unit was returned, inspected, and restored to working condition by the seller or manufacturer before being relisted. The extent of the restoration and warranty coverage varies by seller. Buyers should confirm warranty terms and the return policy before purchasing, as refurbished small appliances carry more uncertainty than new units.
Why does this microwave have 19 power levels?
Nineteen power levels is a Breville design choice aimed at precision cooking. Most microwaves offer 5 to 11 levels, which cover common use cases. The additional levels let you dial into very specific power percentages for tasks like gently defrosting fish, tempering chocolate, or warming sauces without bringing them to a boil. Most users will settle into a handful of those levels in daily use.
How does the convection mode work in a countertop microwave?
Convection mode uses a heating element and a fan to circulate hot air inside the cavity, the same principle as a countertop convection oven. This allows food to brown and crisp on the surface, which microwave energy alone cannot achieve. In a unit like this, you can switch between microwave-only, convection-only, or a combination of both depending on what you are cooking.
