Toshiba MS3-STQ20SA-BK Convection Oven Review
Our verdict
A mid-range countertop convection oven from Toshiba with solid wattage and a clean knob-control design. The 0.7 cubic foot interior is on the smaller side for the price, but the 1,800-watt output and 445 degree maximum temperature give it real cooking muscle for its footprint.

Overview
The Toshiba MS3-STQ20SA-BK is a countertop convection oven priced at $319. It draws 1,800 watts and tops out at 445 degrees F, putting it at the higher end of wattage for countertop models in this category. The interior measures 0.7 cubic feet, which is adequate for a couple of chicken breasts, a small roast, or a personal pizza, but tight for anything larger.
The body is metal with a painted black finish and knob controls, measuring 16.4 x 16.1 x 12.8 inches. That footprint is compact, making it practical for smaller kitchens where counter real estate matters. Toshiba is an established name in countertop appliances with a proven quality record across their oven lineup, which adds a layer of confidence the newer or budget brands cannot match.
With only 41 reviews at a 4.1 rating, the sample size is limited. Early buyers are generally positive, noting even heat distribution and a solid build feel. At $319 it sits in a competitive bracket where alternatives like the Cosori CS130-CFH offer larger capacity at a similar price, so the buying decision comes down to brand preference and whether that compact footprint is an advantage or a limitation for your kitchen.
Pros
- 1,800 watts delivers fast preheat and consistent high heat
- Reaches 445 degrees F, suitable for baking, roasting, and broiling
- Compact 16.4 x 16.1 x 12.8 inch footprint fits smaller counters
- Toshiba brand with an established track record in countertop ovens
- Metal construction feels more durable than plastic-heavy alternatives
Cons
- 0.7 cu ft interior is small for the $319 price, limiting batch size
- Only 41 reviews, so long-term reliability data is limited
- Knob controls only, no digital display or preset cooking modes

Performance notes
At 1,800 watts the MS3-STQ20SA-BK heats up quickly and holds temperature steadily, which is where convection really shines for even browning without hot spots. The 445 degree ceiling covers everything from cookies and casseroles to roasted vegetables and chicken pieces. The 0.7 cu ft chamber means air circulates around food efficiently in that smaller space, which can actually improve results on smaller cuts compared to oversized cavities where food sits too far from the elements. The painted metal exterior holds up to everyday kitchen use, though it will show fingerprints and minor scuffs more readily than a brushed stainless finish.
What buyers say
Early reviewers praise the build quality and how evenly it cooks compared to standard toaster ovens they replaced. A few buyers note the interior is smaller than they expected based on the external dimensions. With 41 reviews the data is thin, but there are no patterns of early failures or major complaints about heating consistency. Sentiment at 4.1 stars is solid for a newer listing.

Frequently asked questions
Will a 9-inch round cake pan fit inside the Toshiba MS3-STQ20SA-BK?
With a 0.7 cu ft interior, a 9-inch round pan is close to the limit. Fit depends on the pan height and depth of the oven cavity. It is worth measuring against the 16.1 x 12.8 inch external base before buying if cake pans are a regular use case.
How does the MS3-STQ20SA-BK compare to other Toshiba convection ovens?
Toshiba's AC25CEW-SS is their high-volume model with over 13,000 reviews at a much lower price point. The MS3-STQ20SA-BK is a newer, higher-wattage option aimed at buyers who want more power and a cleaner modern look, though it costs significantly more.
Does the knob control include a built-in timer?
The knob controls on this model handle temperature and time settings. For specific timer functionality details, check the product listing, as the available spec data confirms knob-control operation but does not detail the exact timer mechanism.
