The TOSHIBA ML2-STC13SAIT(SS) is a premium 1.3 cu ft convection microwave with 1100W output, smart home compatibility, and a 13.58-inch turntable at $479.99. Its convection heating mode and spacious cavity position it as a serious oven replacement for smaller kitchens.
Cooks who want a single appliance that can both microwave and bake via convection, and who have the counter space for a 21.8-inch-wide unit. Smart home users and those needing a large 1.3 cu ft cavity for bigger dishes will find this the most capable unit in this group.

Buyers on a budget, at $479.99 this costs three to four times more than the other microwaves in this set. Those who only need basic reheating will not use the convection feature and would overpay significantly. The 21.8-inch width also rules it out for compact kitchens.

Overview
The ML2-STC13SAIT(SS) is the clear premium outlier in this product set. At 1.3 cubic feet, 1100W, and with convection heating, it operates more like a compact countertop oven that also happens to microwave than a traditional microwave. The 13.58-inch turntable is the largest in this group and accommodates most standard pizza pans, roasting dishes, and 12-inch plates with ease.
Convection heating recirculates hot air around food, allowing this unit to bake, roast, and brown in ways a standard microwave cannot. That makes it useful for crisping reheated foods, baking small batches of cookies, or finishing a casserole with a browned top. The 1100W base power and 5 power levels reflect a simplified control set compared to 10-level budget units, but for convection use, time and temperature matter more than power level count.
Smart home compatibility adds voice-control and app-integration options uncommon at this size. The touchscreen-only interface is clean and modern, matching the silver finish. At $479.99, buyers are paying for the convection capability, the larger cavity, and the smart integration, not just basic microwave function.
Pros
Convection heating enables baking, roasting, and crisping beyond standard microwave function
1.3 cu ft / 1100W is the largest cavity and highest wattage in this group
13.58-in turntable accommodates 12-in dishes, pizza pans, and oval containers
Smart home compatible with touchscreen controls
4.3 stars from 224 reviews for a premium-positioned product
Cons
At $479.99 it costs 3-4x more than most other units reviewed here
5 power levels is notably fewer than the 10-11 levels on budget models
21.8-in width requires substantial counter space
Low monthly purchase volume (2 units) means limited real-world demand signal

Performance notes
At 1100W, this is the highest-wattage unit in this group, and convection mode adds a separate heating dimension entirely. In microwave mode, 1100W heats food roughly 20 percent faster than a 900W unit. In convection mode, the recirculated air can achieve browning and crisping that standard microwaves cannot. The 13.58-inch turntable and 1.3 cu ft cavity are the spacious interior specs. The 5-power-level control is simplified but sufficient for convection-combo cooking where temperature selection dominates over power-level granularity. Dimensions of 19.4 x 21.8 x 12.8 inches require careful counter measurement.
What buyers say
With 224 reviews at 4.3 stars, buyer sentiment is positive for a premium appliance that has a smaller and more deliberate buyer pool. The 4.3-star average is expected for a product at this price, buyers have high expectations and review critically. The low monthly purchase volume (2 units) reflects the niche appeal of a near-$500 countertop microwave with convection. Most positive feedback likely centers on the convection capability and spacious interior.
What is the difference between convection and standard microwave heating?
A standard microwave uses electromagnetic waves to heat food from the inside out, which warms food quickly but does not brown or crisp surfaces. Convection mode uses a fan to circulate heated air around the food, similar to a conventional oven. The ML2-STC13SAIT(SS) can use both methods, microwave for speed, convection for browning, or both together for speed plus texture.
Is $479.99 reasonable for a countertop microwave?
For a basic microwave, no. For a 1.3 cu ft convection microwave with smart home integration and 1100W output, the price reflects the added functionality. If you plan to use convection regularly for baking or crisping, this is effectively a compact oven plus microwave in one unit. If you mainly need standard reheating, far less expensive options exist in this guide.
What smart home systems is this compatible with?
The product is listed as Smart Home Compatible. Specific platform compatibility (Alexa, Google Home, etc.) is not confirmed in the published specs, verify with Toshiba's product page or documentation for the exact smart home ecosystem this unit supports before purchasing.
