Our verdict

A stacked microwave and wall oven for a kitchen that already has the wiring and cabinet space, with air fry in both cavities. Cutout size and circuit rating are not in the listing, so read the install guide first.

Overview

Remodelers who want a microwave and a full wall oven stacked in one opening get both in this built-in electric combo from Cosmo. The upper microwave handles presets, sensor cooking and convection, while the lower oven adds gliding racks and a temperature probe.

Two cooking cavities in one built-in frame free up counter space and let a roast and a side cook together, with air fry and convection on top of baking. Installation is the hurdle: the unit is heavy, needs a high voltage circuit, and the listing leaves out cutout dimensions.

Who it's for

Kitchen remodels and cabinet wall replacements where a microwave and oven share one opening. Renters, or homes without a dedicated high voltage line, should look at freestanding options.

Pros and cons

Pros
  • Air fry function in both cavities
  • Convection for faster, lower temperature cooking
  • Temperature probe for roasts
  • Shabbat mode and timer built in
Cons
  • Needs a 240 volt circuit
  • Cutout dimensions not listed
  • Very heavy, plan for more than one installer
  • Limited warranty covers only one year

Performance notes

Convection circulates hot air, so dishes cook faster and at lower set temperatures, according to the description. The probe in the lower oven reads the food's internal heat, which takes guesswork out of roasts. On the microwave side, sensor cooking and presets handle timing while the turntable rotates the dish for even exposure.
