Our take
Sharp R-120DB is a blue 0.7-cu.-ft. countertop microwave with 600-W output and a 120-V/60-Hz rating. Half Pint is the product-line name; tray diameter, sensor cooking, trim compatibility, commercial duty and a current exact Amazon offer remain unverified.
Consider the blue R-120DB if a compact vintage countertop microwave and its documented 600-W output suit your use. The manual's 120-V/60-Hz supply and approximate 1,030-W/9-A consumption are distinct from cooking output. Check the actual model label, dimensions, cord condition and turntable fit before buying; the tagged search is for the precise blue R-120DB code, not a guarantee of current availability..
If you need more capacity or output, compare a larger model with an exact documented rating. If you want built-in trim or sensor controls, choose a microwave whose specific manual establishes that feature. R-120DB is distinctive for its blue finish, compact case and 600-W output.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The service manual lists 0.7 cu. ft., 600-W RF output and 120-V/60-Hz supply.
- The manual distinguishes microwave output from about 1,030-W/9-A consumption.
- Sharp's brochure maps the DB suffix to blue, and the manual names touch, Compu Cook and Express Defrost controls.
What to weigh up
- The compact cavity and 600-W output are limiting if larger dishes or higher output are priorities.
- Turntable diameter, sensor operation, trim route and commercial-duty classification remain unknown.
- The model is a legacy unit, and its historical ASIN does not establish current offer identity or condition.

What the features mean for you
Read Half Pint as a line name, not the oven volume
Sharp's service manual identifies R-120DB as a microwave in the Half Pint family, and its brochure maps the DB code to blue. The manual's actual cavity is 0.7 cu. ft.; the Half Pint name is a marketing label, not an instruction that the oven has a half-pint capacity. Keep R-120DB separate from Sharp's green, orange, purple and red models. The historical Amazon page did not verify that B00006WNRG currently resolves to this exact blue unit.
Use the compact capacity and case dimensions together
The manual lists a 0.7-cu.-ft. cavity and an outside case about 14 3/8 inches wide, 14 1/8 inches high and 14 inches deep. That compact footprint is a distinct fit advantage for a narrow counter, but it also signals limited dish volume relative to 0.9- or 1.2-cu.-ft. models. The service manual does not state a numeric turntable diameter. Measure cookware and verify clearance rather than assuming that the case size guarantees a particular plate will turn freely.
Keep 600-watt output separate from consumption
Sharp lists 600 W of RF microwave output under the IEC procedure and about 1,030 W/9 A of power consumption. Those numbers describe output and input draw, respectively; they should not be swapped in a comparison. The same service manual specifies 120 V/60 Hz. The lower output and compact size can help distinguish this older design from larger ovens, but they do not predict personal cooking results or establish current parts availability.
Describe the controls without calling them sensor cooking
The service manual lists a touch-control system with Compu Cook, Express Defrost, a popcorn pad, timer and other functions. The brochure calls the Half Pint line Auto-Touch. Those names document control features, but the reviewed exact model material does not confirm the sensor-cooking attribute used in this comparison. Leave it unknown rather than treating a preset or automatic control label as proof of a sensor. Follow the actual operation manual for its named food programs and use cases.
Keep the installation evidence limited to countertop use
Sears PartsDirect classifies R-120DB as a countertop microwave, consistent with Sharp's service manual and compact case. The reviewed sources do not identify an R-120DB trim kit, built-in opening or cabinet installation route. Do not place it in an enclosure by analogy with other Sharp models. Check ventilation and the appliance's own installation instructions; the small shape alone does not establish a safe cabinet option.
Verify condition and duty before using an older appliance
R-120DB is a legacy model, and the available evidence includes an archived Sharp brochure, a service-manual copy and a parts-catalog category. None of these sources establishes commercial foodservice classification. Leave duty unconfirmed and do not promote the unit for shared commercial use. For any old appliance, inspect the exact model label, door, seals, cord, turntable and manual before purchase; the tagged search link does not prove that a current result is the same variant or in any particular condition.
