Our take
The Rival RGST902 manual identifies a 0.9-cu.-ft. countertop microwave with 900-W output and separate 1,350-W consumption at 120 V / 60 Hz. It lists a 19 x 14 5/16 x 11 1/16-in. body and controls for quick cooking, weight-based cooking and defrost, two-stage cycles and +30-second start. The manual also says the microwave is not designed for commercial or laboratory use. It shows a turntable system but gives no diameter. Finish, sensor controls and trim-kit compatibility remain unconfirmed. This review describes the manual, not personal testing or buyer reviews.
Consider RGST902 for a standard counter routine that needs more space than a 0.7-cu.-ft. model but not a large sensor cavity. Measure its 19 x 14 5/16 x 11 1/16-in. footprint, check the grounded 120-V / 60-Hz circuit and preserve ventilation clearances. The manual excludes commercial/laboratory use..
Choose a larger or more powerful model if you require at least 1.2 cu. ft., a 1,000-W output threshold, a documented sensor feature, a known tray diameter or commercial-foodservice qualification.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manual gives 0.9 cu. ft., 900-W output and a complete 120-V / 60-Hz supply rating.
- Quick-cook buttons, cook/defrost by weight, two-stage programming and +30-second start cover several routine tasks.
- Its dimensions and noncommercial restriction are explicit in the exact model manual.
What to weigh up
- The 0.9-cu.-ft. cavity is smaller than the 1.2- and 1.6-cu.-ft. household options in the catalog.
- The manual does not state turntable diameter or document sensor cooking or a trim-kit route.
- The model is expressly not designed for commercial or laboratory use, so it cannot meet a foodservice-duty requirement.
The key details
| Model covered | RGST902 |
|---|---|
| Capacity | The Rival manual lists 0.9 cu. ft. capacity and 900 W output; 1,350 W is the separate power-consumption figure. |
| Microwave output | The manual specifies 120 V / 60 Hz and exterior dimensions of 19 W x 14 5/16 D x 11 1/16 H in. |
| Cooking approach | Controls include quick-cook buttons, weight cooking/defrost, power adjustment, two-stage cooking and +30-second start. |
| Installation options | The manual describes a turntable system without a stated tray diameter and says the appliance is not designed for commercial or laboratory use. |
| Finish and turntable | Finish, sensor controls, trim-kit compatibility and historical Amazon mapping are not confirmed. |

What the features mean for you
A step above the smallest cavity, below a medium-size threshold
Rival rates RGST902 at 0.9 cu. ft., between compact .7-cu.-ft. models and 1.2-cu.-ft. medium options. That can suit routine bowls and plates when a small microwave is too limiting, but it does not meet the finder's 1.2-cu.-ft. preference threshold. The outside measures 19 inches wide, 14 5/16 deep and 11 1/16 high. Measure actual dishes and available counter space; the manual's turntable system has no stated diameter, so the model cannot satisfy a hard tray-size requirement from this evidence alone.
Keep 900-W output apart from the 1,350-W draw
The specification page lists 900 W output and 1,350 W power consumption, plus a 120-V / 60-Hz supply. Use the 900-W value for the finder's output preference and the input line for electrical planning. A higher input number does not make the cooking output 1,350 W. Verify the rating plate, grounding and circuit instructions. Output is a documented rating rather than a measured speed or guarantee that two foods will heat alike.
Quick controls support simple manual routines
The manual documents quick-cook buttons, weight-based cooking and defrost, power adjustment, two-stage programming and a +30-second start. These options allow a user to select a preset time or set sequential stages without requiring a sensor feature. The manual does not establish sensor cooking, so that value stays unknown rather than being set false based on a missing mention. For a shopper who specifically wants humidity-sensor programs, compare with Panasonic NN-SN736W or NN-SN77HS, whose documents name sensor functions.
Use household classification as a firm boundary
The exact RGST902 manual says the appliance is not designed for commercial or laboratory use. This supports commercialDuty=false and excludes it from the professional foodservice case. That statement is stronger than a seller's generic office or break-room wording. If the microwave will be used in a restaurant, shared kitchen or high-volume workplace, select a model the manufacturer identifies for that duty and confirm the site's electrical requirements. Household convenience programs do not turn a residential unit into commercial equipment.
Leave finish and installation accessories unresolved
The manual's exact model code and turntable diagram support the core identity, but the saved sources do not establish a finish, tray diameter or trim-kit option. Keep those fields unknown. The manual describes countertop clearances and ventilation; that is not proof that a built-in kit exists or that another Rival model's accessory fits. Check the exact model label and cabinet opening before planning a permanent installation. If finish is important, rely on a directly verified offer page rather than inferring it from RGST902 or a shared control-panel photograph.
Search for the exact Rival code
The historical ASIN did not prove a current exact-model offer. The affiliate destination searches Rival RGST902 and carries buyershortlists-20. Verify the code, condition, included glass tray and the installation guide in any result. This search route avoids claiming present stock or seller identity. If the seller advertises a different brand or shares a capacity/output combination, do not merge that listing without an exact model crosswalk.
What else to compare
Danby DMW7700BLDB is smaller at 0.7 cu. ft. and 700 W, while Panasonic NN-SN736W provides 1.6 cu. ft., 1,250 W and sensor cooking. Both alternatives have their own tray/installation unknowns. RGST902 sits between them with a documented 0.9-cu.-ft. cavity and 900-W output, but its manual excludes commercial service.
Before you buy
What capacity and output does RGST902 have?
The manual lists 0.9 cu. ft. and 900 W output, separate from 1,350 W power consumption.
What electrical supply does Rival specify?
The manual lists 120 V / 60 Hz and says to use a properly grounded connection.
Is RGST902 suitable for commercial foodservice?
No. Its exact manual says the microwave is not designed for commercial or laboratory use.
Does it have sensor cooking?
The reviewed manual does not establish sensor cooking, so the profile leaves that feature unknown.
How large is the turntable?
The manual shows a turntable system but does not give a diameter for the exact model.
