The retained reference is $2,549 current U.S. recommended retail price. Cabinet, electrical, delivery, installation and matching-oven work are separate. Have the seller and qualified installer confirm model, cutout, trim, door, ventilation, nameplate, circuit, outlet or junction and accessories before payment.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
Cabinet, electrical, delivery, installation and matching-oven work are separate. Confirm stock, authorized U.S. support, tax, return terms and exact installation scope.
MB30WS suits a Masterpiece stack that values a flush drop door and local microwave simplicity without paying for a convection speed-oven circuit and mode set.

Owner experience
Owner evidence is retained as a fit, circuit, cookware, controls, cleaning and service checklist for Masterpiece 30-Inch Built-In Microwave, not a performance, leakage, failure or repair rate.
Reports are self-selected and span different cabinets, circuits, installers, cookware, food, modes, cleaning, accounts, firmware, climates and service regions. They cannot prove population speed, evenness, doneness, temperature, leakage, fire, electrical, reliability or repair outcomes.Self-selected exact-model discussions surface cabinet-fit surprises, door clearance, outlet or junction access, turntable and pan fit, control behavior, fan sound, cleaning, app setup, parts and service. Cabinets, circuits, cookware, food, modes, cleaning and service regions differ, so these reports do not establish speed, doneness, temperature, leakage, failure or repair rates.
Choose microwave-only simplicity only if the installed-price premium and stack alignment remain worthwhile
