Pros
- 12 cooking functions including air fry, convection, broil, and sensor cooking for unmatched versatility.
- Sensor cooking detects food moisture and adjusts settings, eliminating guesswork.
- Stainless steel build is durable, rust-resistant, and matches modern kitchen decor.
- Full accessory set allows for dual-level cooking and drip-free grilling.
- Lifetime technical support and responsive customer service.
Cons
- Heavy weight (90 pounds) requires two people for installation and sturdy cabinetry.
- Higher price point compared to standard microwaves, justified by multi-function capability.
- No customer reviews yet, so long-term reliability is unverified.
The AAOBOSI 24-inch built-in microwave convection oven is a powerhouse of culinary versatility. Designed for families who want to maximize kitchen efficiency, this unit combines a microwave, air fryer, convection oven, broiler, and more into one sleek stainless steel package. With a spacious 1.6 cu ft capacity and 1000W microwave power, it handles everything from quick reheats to full meals.
Standout features include sensor cooking that automatically detects food moisture and adjusts time and power for perfect results every time. The air fry function offers 10 presets plus a manual DIY mode, letting you achieve crispy fries and chicken with minimal oil. The convection mode with 1700W ensures even baking, while the broil element adds a high-heat finish for steaks and casseroles.
Build quality is impressive: the stainless steel exterior resists fingerprints and scratches, and the coated metal interior makes cleanup a breeze. The drop-down door and glass touch panel feel premium, though the heavy unit requires sturdy cabinetry for built-in installation. Accessories are generous, including a turntable, ceramic tray, grill rack, grill pan, and wire mesh rack.
Potential drawbacks include the weight (90 pounds) and the need for a 20A circuit, which may require an electrician in older homes. As a new model with no reviews yet, long-term durability is unknown, but AAOBOSI offers lifetime technical support for peace of mind.
Overall, this is a top choice for anyone seeking a feature-rich, space-saving appliance that replaces multiple countertop devices. It excels in performance and design, making it a worthy investment for serious home cooks.

Buying Guide
Installation Flexibility
Not all built-in microwaves offer the same installation options. Some are designed to slide into a cabinet cutout, while others can go under the counter or even inside an island. The Sharp SMD2420MS 24-Inch Built-In Microwave Drawer excels here with its versatile drawer design that fits walls, islands, peninsulas, and under-counter spaces without extra hardware. The 24 in. Haven Collection 1.2 cu. ft. Built-in from COSMO is a standard built-in model, so measure your cabinet space carefully.

Capacity and Interior Space
If you often reheat large casserole dishes or platters, interior dimensions matter more than the cubic foot rating. The Sharp drawer offers a spacious 17 by 16 inch interior, ideal for oval platters. The COSMO model also provides 1.2 cubic feet of space, while the AAOBOSI 30 Inch Built-in Microwave Oven Air Fryer is larger at 30 inches, offering more room for multiple dishes or air frying baskets. Consider your typical cooking needs before deciding.
Cooking Technology and Presets
Modern built-in microwaves come with smart features that simplify cooking. The Sharp model uses Sensor Cook technology that automatically adjusts cooking time by detecting moisture levels. COSMO’s Haven Collection offers four automatic presets for melt, soften, popcorn, and beverage functions plus smart defrosting with weight or time options. The AAOBOSI combo unit adds air frying and convection capabilities, making it a versatile countertop replacement.

Ease of Use and Safety
Drawer style microwaves like the Sharp model offer effortless access with a button press and smooth close with a gentle nudge. Its angled touch control panel is easy to read, and the control lock prevents accidental use. The COSMO unit includes a defrosting rack and straightforward presets. The AAOBOSI unit is larger and may require more counter space, but it offers multiple cooking methods in one appliance. Prioritize features that match your daily routine.
Final Thoughts
After reviewing these three models, our recommendation depends on your kitchen layout and cooking habits. For maximum installation flexibility and a modern drawer design, choose the Sharp SMD2420MS 24-Inch Built-In Microwave Drawer, which offers exceptional convenience and sensor cooking. If you want a powerful built-in microwave with air frying and convection capabilities for versatile meal prep, the AAOBOSI 30 Inch Built-in Microwave Oven Air Fryer is a fantastic all-in-one solution. Both are top contenders among the best built in microwave brands this year.
Frequently Asked Questions
Can a built-in microwave be installed under the counter?
Yes, many built-in microwaves are designed for under-counter installation. The Sharp SMD2420MS drawer model is particularly well suited for this, as it requires no additional hardware and fits seamlessly beneath countertops. Always check the manufacturer’s specifications for your chosen model.
What is the difference between a built-in microwave and a countertop microwave?
A built-in microwave is designed to be installed into a cabinet or wall cutout, creating a flush, integrated look. Countertop models sit on the counter and are not meant for enclosed installation. Built-in units often have better ventilation and trim kits for a professional finish. For more comparisons, see our breville smart oven air fryer vs cuisinart article.
Do built-in microwaves come with a trim kit?
Some built-in microwaves include a trim kit, but many require a separate purchase. The models we reviewed from Sharp and COSMO are designed for built-in use and may need a trim kit for a seamless installation. Check the product details or contact the manufacturer to confirm what is included.
How much space do I need for a 30 inch built-in microwave?
A 30 inch built-in microwave like the AAOBOSI model requires a cabinet cutout that matches its width, typically 30 inches wide by about 18 to 20 inches tall. Measure your available space carefully and consult the installation manual for exact dimensions. This larger size is ideal for households that cook frequently or need extra capacity.
