The Westinghouse WMB4425DSC is a built-in dark stainless combination microwave with convection and grill functions. Westinghouse lists a 44L capacity and 900W microwave output; CHOICE lists 39L as usable volume. Those figures describe different labels, and the available listings do not explain how they were measured. The key practical checks are whether the appliance fits your cabinet and whether its hardwired connection suits your installation.
What the WMB4425DSC offers
Westinghouse NZ describes the WMB4425DSC as a “44L built-in Dark Stainless steel combination microwave with convection and grill functionality.” It is designed for built-in installation, rather than as a countertop microwave.

- Microwave: 900W output, according to Westinghouse.
- Convection and grill: The manufacturer lists convection cooking and a radiant grill. Its fact sheet also identifies a grill rack.
- Combination cooking: Westinghouse lists three combination modes.
- Automatic programs: The product page lists 13 Auto Cook programs, Auto Defrost, and 10 programmed functions. These are the labels Westinghouse uses; the available information does not establish that “programmed functions” and Auto Cook programs are the same count.
- Controls and safety: The page lists touch controls, child safety, and 10 power levels.
- Interior: Westinghouse lists a stainless steel interior.
Westinghouse says the predefined combination modes can brown, crisp, and flavor food in less time than a conventional oven. That is a manufacturer claim, not an independently verified result. Its category description says convection microwaves combine microwave functions with an oven’s grill function to help produce crisper results than a traditional microwave; that, too, is Westinghouse’s characterization.

Capacity: 44L listed, 39L usable
Westinghouse NZ gives the appliance a 44L capacity. CHOICE’s exact-model listing gives a 39L usable volume, a usable cavity measuring 22 × 42 × 42 cm, and a usable shelf diameter of 34 cm. The sources do not provide a shared measurement method or reconcile the capacity figures, so treat 44L and 39L as separately attributed figures rather than assuming one corrects the other.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
For day-to-day planning, the usable shelf diameter and cavity dimensions may be more useful than the headline capacity: check that your usual dishes fit. CHOICE lists a 34 cm usable shelf diameter.
Will it fit, and how is it connected?
Westinghouse NZ lists overall dimensions of 595 mm wide × 568 mm deep × 454 mm high. CHOICE’s listing gives claimed external dimensions of 45 × 60 × 60 cm, which do not match the manufacturer’s figures. The listings do not explain the discrepancy; use the current manufacturer dimension sheet and confirm the relevant dimensions for your installation before ordering.

The Westinghouse page says the unit is hardwired. Because it is both built-in and hardwired, do not rely on exterior dimensions alone to decide whether it will fit. Verify the specified cabinet cutout, clearances, ventilation, and site electrical requirements against current installation documentation, and consult a qualified installer. The available product information does not establish cutout measurements or make a claim about installation difficulty.

What the available review evidence shows
Westinghouse NZ displayed a rating of 4.1 from 71 customer reviews on its product page when accessed in 2026. This is a user-review aggregate, not a controlled comparison of cooking performance.
CHOICE’s public exact-model listing includes specifications and indicates that its Expert Rating is available to members. The rating itself is not visible in the public listing information available here, so no CHOICE score can be reported. There is also no hands-on testing evidence here for cooking speed, evenness, noise, cleaning, usability, or reliability. Those qualities should not be inferred from the feature list or customer-review average.

WMB4425DSC versus WMB4425SC
The model suffix matters: WMB4425DSC is the dark stainless version, while WMB4425SC is the stainless-steel version. Confirm the full model code on a retailer listing and on the appliance documentation so that finish and specifications are not mixed across the two models.
