Our take
The Sharp R-320HQ is a bisque 1.2-cu.-ft. countertop microwave with 1,200-W output, sensor functions and a 12 5/8-in. tray. It offers a sensor-focused alternative to Sharp's smaller convection R830BS; it does not document convection cooking.
Choose it for a bisque countertop microwave with sensor programs and a known tray size. Pick a convection model when browning or baking is the priority..
Avoid it if you need a convection oven, a trim-kit installation, or proof that an old Amazon ASIN still identifies this exact bisque variant.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The exact listing distinguishes R320HQ as the bisque, countertop member of the R-320H line.
- The product record lists a 12 5/8-in. turntable and 1.2-cu.-ft. capacity for measuring everyday cookware.
- Sensor cooking and sensor reheat are documented, along with multiple defrost options.
What to weigh up
- The exact listing says this model has no convection cooking and no optional built-in trim kit.
- Its 1,680-W AC power requirement is separate from its 1,200-W microwave output and needs circuit planning.
- The historic Amazon ASIN is not asserted to map to a current exact model or package.

What the features mean for you
Preserve the bisque HQ variant
The retailer's exact R320HQ record names the bisque finish, and the Sharp family operating manual groups the HQ code with related HW and HK versions. A separate saved record identifies R-320HW as white, so those suffixes are meaningful variant boundaries. Use the complete R-320HQ code in an Amazon search and check that a listing is bisque rather than substituting the white HW model or inferring a black HK model from the family manual. The historical ASIN is not used as an exact current offer link.
Compare the cavity and tray with your regular dishes
The exact R320HQ listing gives 1.2 cu. ft. and a 12 5/8-in. carousel turntable. The known diameter is useful when checking plates, but a dish also needs room to rotate inside the cavity. The family manual gives interior dimensions that can assist planning, while the exact retailer listing describes this as a mid-size countertop unit. Measure the dish base and the space around the tray rather than assuming a nominal cubic-foot figure guarantees fit. A larger serving dish may be better served by a roomy sensor model such as Whirlpool GT4175SPS or Toshiba ML-EM62P(SS).
Use sensor programs for the jobs the manual names
The exact listing and family manual identify sensor cooking, sensor reheating and defrost options. The product description says its sensor settings automate time and power for listed food types, which changes the routine from entering every time manually. It also includes ordinary timed cooking and multiple power levels. That control set can be more useful than a simple one-touch timer if you frequently use the documented menus, but it does not establish that every dish needs the same automatic program. If you want to bake or brown, select a model with convection instead; R320HQ is microwave-only.
Check the separate cooking and electrical ratings
The family manual lists 1,200 W microwave output and a 1,680-W AC power requirement, plus 120 V and 60 Hz. Output describes microwave cooking power; the AC requirement describes the electrical service and should not be replaced by the smaller output number when planning a circuit. Follow the individual model plate and instructions for current, grounding, plug and clearances. The exact model's U.S. voltage and frequency support its standard-supply profile, but this is not a substitute for checking the unit's full electrical label.
Keep its installation on the counter
The exact R320HQ record identifies countertop placement and says no optional built-in trim kit. Treat this as a counter appliance rather than a hidden cabinet insert. A countertop location still needs suitable airflow and access to the controls and door. The reviewed records do not establish a manufacturer commercial-duty class, so shared foodservice use should not be inferred from its sensor menus or wattage. Compare the required width and depth with the available counter, and choose a separately verified model if you need a built-in look.
