Our take
Avanti MO8004MST is an exact-model countertop microwave with a documented 0.8-cu.-ft. cavity and 700 W microwave output. Its manual separately lists 1,050 W power consumption on 120-V/60-Hz power, so the input and output figures should not be mixed when planning an outlet. The controls include six food presets, weight-based cooking and defrost, speed defrost, a 12-hour clock and kitchen timer. The manual directs countertop placement on a flat, steady surface with five inches at both sides and space behind the unit. It includes a glass tray but gives no tray diameter. Office Depot corroborates the model and countertop form factor, while its exterior dimensions differ slightly from the manual. Sensor cooking, trim-kit compatibility and exact finish remain unknown. The historical Amazon ASIN did not load; the tagged exact-model search is used.
Avanti MO8004MST is a small countertop microwave for buyers whose first checks are a documented 0.8-cu.-ft. cavity, 700-W microwave output and a glass turntable. Its manual lists 1,050 W power consumption at 120 V/60 Hz, which must not be confused with output when considering the circuit. It calls for a grounded, exclusive 15-A, 120-V outlet, at least five inches from each sidewall and space away from the rear wall. Office Depot corroborates the exact model, countertop form factor and ten power levels. The manual lists automatic food presets, weight-based cook/defrost and speed defrost, but those menus alone do not prove sensor cooking. The available manual and listing differ slightly on exterior dimensions, so use neither as a precise fit guarantee. The frozen title's mirror-door detail is not independently confirmed, and the historical Amazon ASIN is unverified; the affiliate link searches the exact model..
Do not choose this microwave if you need a large cavity, higher documented output, a confirmed tray diameter, sensor cooking, built-in trim compatibility, or a precise footprint established consistently by the available sources.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The exact Avanti manual documents both cooking output and electrical consumption instead of conflating the two ratings.
- The manual lists the 0.8-cu.-ft. capacity, 120-V/60-Hz supply, grounded outlet and glass tray assembly.
- Cook-by-weight, defrost-by-weight, speed defrost, timer and six named food presets are documented controls.
- A second exact-model listing confirms countertop form factor, ten power levels and the Avanti model code.
What to weigh up
- The documented 0.8-cu.-ft. cavity and 700-W output are modest compared with larger ovens.
- The manual requires five inches at both sidewalls and space behind the oven for ventilation.
- The manual and retailer give slightly different exterior dimensions, and neither establishes the exact turntable diameter.
- Sensor cooking, trim-kit fit, mirror-finish detail and the historical Amazon ASIN remain unconfirmed.
The key details
| Model covered | MO8004MST |
|---|---|
| Capacity | Avanti's exact manual lists a 0.8-cu.-ft. cavity and outside dimensions of 10-5/16 × 17-13/16 × 14-3/16 inches; Office Depot's exact-model dimensions differ slightly, so verify a tight fit. |
| Microwave output | The manual lists 700 W microwave output separately from 1,050 W consumption at 120 V/60 Hz and requires a grounded exclusive 15-A, 120-V outlet. |
| Cooking approach | Controls include six auto-cook presets, cook-by-weight, defrost-by-weight, speed defrost, ten power levels, a 12-hour clock and timer. The documents do not confirm sensor cooking. |
| Installation options | Avanti directs flat, steady countertop placement, at least five inches from both sidewalls and away from the rear wall; keep vents clear. No exact compatible trim kit is documented. |
| Finish and turntable | The oven uses a glass tray with no published diameter. Finish is unconfirmed, and the manual/retailer footprints conflict. Historical ASIN B00HZ55ZIK failed; use the tagged exact-model search. |

What the features mean for you
The exact model is a countertop microwave
The frozen record names Avanti MO8004MST, and the Avanti-authored manual uses that same model code on its cover and parts page. It is an instruction manual for a microwave oven, not a microwave accessory or an unrelated small appliance. For placement, Avanti says to set the oven on a flat, steady surface; Office Depot separately identifies the exact MO8004MST as countertop form factor. That combination supports the in-category decision. The source title includes “Mirror Finish Door,” but the manual pages and model-specific listing reviewed here do not establish the finish. I leave finish out of the profile instead of treating the title wording or “MST” suffix as proof of material or color.
Keep the cooking output separate from input consumption
Avanti lists 700 W output and, on a separate line, 1,050 W power consumption at 120 V/60 Hz. Output describes the microwave's stated cooking energy; consumption is the electrical input rating. The manual also directs the owner to a grounded, exclusive outlet and specifies a standard 15-A, 120-V supply in its operating instructions. A shopper should use the input and outlet requirements for electrical planning, not the 700-W figure. The 0.8-cu.-ft. capacity and 700-W output are useful comparison filters, but they are not a promise about actual cook time or an outcome measured in testing.
Automatic presets are not proof of a cooking sensor
The manual lists presets for baked potato, popcorn, pizza, beverage, frozen dinner and reheat. It also names cook-by-weight, defrost-by-weight, speed defrost, a 12-hour clock and kitchen timer. Office Depot lists ten power levels. These features describe available controls; the documents do not state that the presets use humidity or temperature sensing. Sensor cooking therefore remains unknown rather than true or false. Buyers who need that function should use the manufacturer name and exact model code to request explicit confirmation. This careful distinction avoids upgrading an ordinary auto-menu list into an undocumented sensing feature.
Leave room at the sides and behind the unit
Avanti says to keep the oven at least five inches away from both sidewalls and away from the rear wall to provide ventilation. It also says not to block air vents and not to put anything on top. These instructions can affect shelf width and depth, especially in a compact kitchen where the microwave seems small enough to squeeze beside a wall. The manual does not specify an exact rear distance or a numeric top clearance in the reviewed page, so neither should be invented. Treat the five-inch side instruction and the rear-wall wording as setup requirements, then check the full manual and the actual installation space before use.
The glass tray is present, but its diameter is unknown
The manual lists a glass tray and roller assembly among the parts and says both the tray and roller guide must remain in place during cooking. That establishes a turntable-style rotating tray, but it does not give the tray diameter. If a platter's width is close to the usable interior, the published 0.8-cu.-ft. cavity volume is not a substitute for a tray measurement. Ask Avanti for a model-confirmed dimension rather than transferring a diameter from another 0.8-cu.-ft. model. The matching profile keeps turntableDiameterIn null because no source reviewed here establishes the number.
Do not rely on one source for the exact footprint or finish
The manual's external measurements are 10-5/16 × 17-13/16 × 14-3/16 inches in height, width and depth. Office Depot lists 10-1/4 × 18 × 14-1/4 inches. The difference is small, but a shelf opening can be tight, so neither figure is presented as a resolved exact footprint. The frozen title also claims a mirror-finish door, while the available exact manual and retailer listing do not verify that finish. Confirm the dimensions and appearance of the specific unit with Avanti or the seller if either detail decides fit. Neither question changes the verified model or countertop classification.
The manual describes household rather than industrial duty
Avanti says the microwave is designed to heat, cook or dry food and is not designed for industrial or laboratory use. It does not present MO8004MST as a foodservice oven; the profile therefore marks commercialDuty false. A buyer equipping a business kitchen should select a model with explicit commercial-duty documentation rather than assuming that a standard grounded household plug or a set of automatic menus establishes commercial suitability. Sensor cooking and optional built-in trim compatibility are also not named in the reviewed material and remain null.
Use an exact-model search instead of the historical ASIN
The frozen row associates ASIN B00HZ55ZIK with the MO8004MST title. When checked, that Amazon page returned an internal error and did not show model or variant details. The manual and Office Depot independently establish the product model, but they do not prove which ASIN Amazon currently uses for it. For that reason the affiliate destination searches the exact Avanti model and carries the buyershortlists-20 tag; B00HZ55ZIK is recorded only as the unverified historical route. The model is not dropped just because the ASIN mapping is unavailable.
What else to compare
If 0.8 cu. ft. or 700 W is below your requirement, compare countertop models whose exact manufacturer documents support a larger capacity or higher cooking-output threshold. Do not substitute a model's input consumption for its microwave output.

The decision
Avanti MO8004MST is a verified countertop microwave with 0.8 cu. ft. capacity and 700 W output, while its manual separately lists 1,050 W consumption at 120 V/60 Hz. The manual requires a grounded exclusive outlet, five inches at both sides and space behind the oven. It documents food presets and defrost controls, but not sensor cooking, trim-kit compatibility or tray diameter. The manual and retailer dimensions differ slightly, and the mirror-finish title detail is unconfirmed. Amazon B00HZ55ZIK could not be verified, so use the tagged exact-model search.
